Mulberry Basque Cheesecake (Air Fryer Version) – Overnight Breakfast for Two

Steps

1. 1

   Step 1

   Important notes to remember: 1. Do not whip the heavy cream — use it liquid straight from the carton. 2. Do not vigorously beat the eggs or batter. Fewer bubbles = fewer cracks. 3. Do not mash or purée the mulberries — only dice them. 4. Soft, thin mulberry stems can stay; hard, thick stems must be removed. 5. Frozen shredded cheese goes in straight — no need to thaw. 6. Make it tonight, refrigerate overnight, and enjoy the best texture at breakfast tomorrow.

   ✅ Done when: Important notes to remember: 1. Do not whip the heavy cream — use it liquid straight from the carton. 2. Do no. Finished: Heat the pan or oil to about 180 C before adding the mixture; the surface should sizzle gently on contact.

   Watch out: Treating these notes as optional — whipping the cream, mashing the berries, or beating the batter will each cause a specific failure (weeping, sinking, or a cracked top), so read them before you start.

   If The finished cake weeps liquid and develops a watery layer at the bottom.:

   Pour the heavy cream straight from the carton in its liquid state; never whip it.

   If The baked cake has a cracked, uneven top.:

   Stir gently and slowly with a spatula; fold rather than whisk so minimal air is incorporated.

   Step 210 min

   

   Mulberry prep (key to preventing a watery, sunken cake): 1. Wash all mulberries and pat dry. 2. Remove any hard, thick, or dry black stems; keep the soft thin ones. 3. Divide into two portions — one for the filling (diced into small pieces) and one for decoration (left whole). 4. Sprinkle a small spoonful of sugar over the diced pieces, mix gently, and let sit for 10 minutes to draw out excess moisture. 5. After macerating, gently pour off the released sugary liquid (this is crucial to prevent the cake from weeping and collapsing).

   Watch out: Skipping the 10-minute sugar maceration or forgetting to pour off the released juice — leftover berry liquid is the main cause of a watery, sunken cake.

   If The cake turns out watery, weeps juice, and sinks in the middle after baking.:

   Sprinkle sugar over the diced berries, rest for 10 minutes, then gently pour off all the released liquid before folding them in.

   If Chewy, fibrous, unpleasant bits throughout the finished cake.:

   Remove every hard or thick stem before dicing; only soft, thin stems may stay.

   Step 3

   1. Cheese & butter base (melt over a water bath): Tear 4 cheese slices into small pieces and add the butter to a clean, dry, oil-free bowl. Place the bowl over warm (not hot) water and stir gently until the cheese and butter are completely melted and smooth. ❌ Do NOT use boiling water — high heat causes the cheese to clump and separate. ❌ Do NOT add the frozen shredded cheese at this stage. Speed tips for melting cheese: - Tear the slices into fingernail-sized pieces and cut the butter into small cubes — smaller pieces melt faster. - Use warm water (~50 °C / comfortably hot to touch) instead of boiling water for more stable, even melting. - Rest the bowl on the rim of the pot, not directly on the bottom, to avoid localized overheating. - In a rush? Microwave on low/defrost in 10-second bursts, stirring between each, 2–3 rounds total. (Never use high power — it will scorch the cheese.)

   ✅ Done when: 1. Cheese & butter base (melt over a water bath): Tear 4 cheese slices into small pieces and add the butter to. Finished: Heat the pan or oil to about 180 C before adding the mixture; the surface should sizzle gently on contact.

   Watch out: Using boiling water (or high microwave power) — overheating makes the cheese clump, separate, or scorch. Keep the water warm, around 50 F/120 F equivalent of comfortably hot to the touch.

   If The cheese and butter turn grainy, clumpy, or split into an oily mess.:

   Melt over warm water around 120°F (comfortably hot to the touch) with the bowl resting on the pot rim, or microwave on defrost in 10-second bursts, stirring between each round.

   If The base seizes with half-melted shreds and will not smooth out.:

   Keep the shredded cheese out of the water bath and fold it in only at the end, straight from the freezer.

   2. Add sugar & heavy cream: Pour in all 25–30 g of caster sugar and stir until fully dissolved. Add the heavy cream in small increments, stirring gently each time. ❌ Do NOT pour all the cream in at once — it can cause uneven mixing and separation.

   ✅ Done when: 2. Add sugar & heavy cream: Pour in all 25–30 g of caster sugar and stir until fully dissolved. Add the heavy. Finished: Heat the pan or oil to about 180 C before adding the mixture; the surface should sizzle gently on contact.

   Watch out: Pouring all the heavy cream in at once — it can cause uneven mixing and separation. Add it in small increments, stirring gently after each addition.

   If The mixture looks curdled, with streaks of fat and liquid that will not blend.:

   Add the cream in small increments, stirring gently after each addition until fully absorbed.

   If A grainy, gritty texture in the finished cake.:

   Stir until the sugar crystals are completely dissolved and the mixture feels smooth before adding the cream.

   3. Add thick yogurt: Pour in 70 g of thick yogurt and fold gently until just combined. ⚠️ You must use thick yogurt — runny yogurt will make the batter too thin and the cake will not set properly.

   ✅ Done when: 3. Add thick yogurt: Pour in 70 g of thick yogurt and fold gently until just combined. ⚠️ You must use thick y. Finished: Heat the pan or oil to about 180 C before adding the mixture; the surface should sizzle gently on contact.

   Watch out: Using runny yogurt — thin yogurt waters down the batter and the cake will never set properly. Stick with a thick, spoonable yogurt.

   If The batter is thin and the cake never sets, staying runny even after chilling.:

   Use a thick, spoonable yogurt (Greek-style or strained); if only runny yogurt is available, strain it through cheesecloth first to remove the whey.

   If Small bubbles in the batter and a slightly cracked top after baking.:

   Fold gently just until the yogurt is incorporated, then stop.

   4. Add eggs one at a time (key to preventing cracks): Add the eggs one by one. Stir the first egg until fully incorporated (no visible streaks) before adding the second. Fold gently and slowly throughout — never whisk vigorously or beat. ❌ The harder you stir, the more bubbles form, and the more the surface will crack during baking.

   ✅ Done when: 4. Add eggs one at a time (key to preventing cracks): Add the eggs one by one. Stir the first egg until fully. Finished: Heat the pan or oil to about 180 C before adding the mixture; the surface should sizzle gently on contact.

   Watch out: Adding both eggs at once or stirring vigorously — extra bubbles from hard beating are what crack the surface during baking.

   If The cake surface cracks during baking.:

   Add the eggs one at a time, stirring the first until no streaks remain before adding the second, and keep the stirring slow and gentle.

   If Yellow egg streaks or uneven pockets in the baked crumb.:

   Wait until the first egg is completely blended with no visible streaks before adding the next.

   5. Sift in dry ingredients (cornstarch + cake flour): Mix 6 g cornstarch and 2 g cake flour, then sift into the batter. Fold gently just until no dry streaks remain, then stop immediately. ❌ Over-mixing develops gluten and makes the cake dense and tough instead of silky.

   ✅ Done when: 5. Sift in dry ingredients (cornstarch + cake flour): Mix 6 g cornstarch and 2 g cake flour, then sift into th. Finished: Heat the pan or oil to about 180 C before adding the mixture; the surface should sizzle gently on contact.

   Watch out: Over-mixing after sifting — once the cornstarch and cake flour are in, extra stirring develops gluten and turns the cake dense and tough instead of silky.

   If The cake is dense, tough, and chewy instead of silky.:

   Sift the dry ingredients in, fold just until no dry streaks remain, and stop immediately.

   If Small dry lumps or white specks in the baked cake.:

   Always sift the combined dry ingredients into the batter before folding.

   6. Add frozen shredded cheese: Add 30 g of frozen shredded cheese straight from the freezer — no need to thaw. Fold gently until the shreds are evenly dispersed. ❌ Do NOT stir hard or heat the shredded cheese — it can release oil and clump.

   ✅ Done when: 6. Add frozen shredded cheese: Add 30 g of frozen shredded cheese straight from the freezer — no need to thaw. Finished: Heat the pan or oil to about 180 C before adding the mixture; the surface should sizzle gently on contact.

   Watch out: Stirring hard or warming the shredded cheese — friction and heat make the shreds release oil and clump. Fold gently and keep them straight from the freezer.

   If Oily, clumped cheese pockets in the batter and baked cake.:

   Fold gently just until the shreds are evenly dispersed, and keep them frozen until the moment they go in.

   If Soggy, wet shreds that smear instead of staying distinct.:

   Add the shreds straight from the freezer with no thawing.

   7. Strain the entire batter (essential for a smooth texture): Pass the entire batter through a fine-mesh sieve. This removes air bubbles and small cheese lumps, giving you a smooth surface and silky texture.

   ✅ Done when: 7. Strain the entire batter (essential for a smooth texture): Pass the entire batter through a fine-mesh sieve. Finished: Heat the pan or oil to about 180 C before adding the mixture; the surface should sizzle gently on contact.

   Watch out: Skipping the sieve to save time — leftover cheese lumps and air bubbles are what ruin the smooth top and silky texture.

   If A pocked, lumpy surface and a less silky crumb.:

   Pass the entire batter through a fine-mesh sieve before folding in the berries.

   If Cheese lumps are still visible in the strained batter.:

   Let the batter flow through gently, tapping the sieve; scrape off and discard any lumps left behind.

    8. Fold in the mulberry pieces: Add the macerated, drained mulberry dice. Fold just 2–3 times — do not mash the fruit.

    ✅ Done when: 8. Fold in the mulberry pieces: Add the macerated, drained mulberry dice. Fold just 2–3 times — do not mash th. Finished: Heat the pan or oil to about 180 C before adding the mixture; the surface should sizzle gently on contact.

    Watch out: Mashing the berries or folding more than a few times — crushed fruit bleeds purple juice and streaks the batter.

    If Purple streaks and bleeding juice marbling the batter and cake.:

    Fold just 2-3 gentle turns, stopping as soon as the berries are distributed.

    If The cake bakes up slightly flat and dense.:

    Keep folding to a minimum; a few turns is enough to distribute the berries.

    9. Pour into the mold and arrange: A 17 cm foil bowl is recommended. Lightly grease the inside with butter for easy release. Pour the batter to about 70% full. Gently arrange whole mulberries on the surface for decoration (don't press them in too deep).

    ✅ Done when: 9. Pour into the mold and arrange: A 17 cm foil bowl is recommended. Lightly grease the inside with butter for. Finished: Heat the pan or oil to about 180 C before adding the mixture; the surface should sizzle gently on contact.

    Watch out: Overfilling the mold or pressing the whole mulberries in deep — batter above 70% can overflow, and buried berries sink as the cake bakes.

    If Batter overflows and drips into the air fryer while baking.:

    Fill the greased 17 cm foil bowl only to about 70% full.

    If The decorative mulberries sink below the surface and disappear.:

    Gently rest the whole mulberries on the surface without pushing them in.

    10. Air fryer baking: Temperature: 155 °C (310 °F) Time: 22–25 minutes ✅ Doneness test: The edges should be set and lightly golden; the center should have a gentle, jiggly wobble. ❌ Do NOT bake until the center is firm — the cake will turn dry and overcooked.

    ✅ Done when: 10. Air fryer baking: Temperature: 155 °C (310 °F) Time: 22–25 minutes ✅ Doneness test: The edges should be se. Finished: Heat the pan or oil to about 180 C before adding the mixture; the surface should sizzle gently on contact.

    Watch out: Baking until the center is firm — that overcooks and dries the cake. Also note air fryers run hot and uneven, so start checking at the 22-minute mark.

    If The cake is dry and overcooked.:

    Start checking at the 22-minute mark; remove the cake when the edges are set and lightly golden but the center still jiggles softly.

    If A burnt top with an underbaked, liquid center.:

    Verify the temperature with a separate thermometer, rotate the mold partway through baking, and tent with foil if the top browns too fast.

    Step 13

    11. Cool completely at room temperature. (Putting a hot cake straight into the fridge will cause it to collapse.)

    ✅ Done when: 11. Cool completely at room temperature. (Putting a hot cake straight into the fridge will cause it to collaps. Finished: Heat the pan or oil to about 180 C before adding the mixture; the surface should sizzle gently on contact.

    Watch out: Refrigerating the cake while it is still hot — the sudden temperature change traps steam and causes the cake to collapse.

    If The cake collapses or sinks dramatically.:

    Let the cake cool completely at room temperature before chilling.

    If The cake continues to cook and dries out after baking.:

    Remove the cake from the air fryer as soon as it is done and cool it on a wire rack.

    Step 14

    12. Cover tightly with plastic wrap and refrigerate.

    ✅ Done when: 12. Cover tightly with plastic wrap and refrigerate. Finished: Heat the pan or oil to about 180 C before adding the mixture; the surface should sizzle gently on contact.

    Watch out: Covering loosely — an unsealed wrap lets the surface dry out, form a skin, and pick up fridge odors.

    If A dry, leathery skin forms on the surface and the cake picks up fridge odors.:

    Press the wrap directly against the surface or seal the container tightly before refrigerating.

    If Condensation droplets make the top wet and sticky.:

    Confirm the cake is fully at room temperature before covering it.

    13. Slice and enjoy after overnight chilling — that's when you get the dense, gooey, authentic Basque cheesecake texture.

    ✅ Done when: 13. Slice and enjoy after overnight chilling — that's when you get the dense, gooey, authentic Basque cheeseca. Finished: Heat the pan or oil to about 180 C before adding the mixture; the surface should sizzle gently on contact.

    Watch out: Slicing before the overnight chill is complete — a warm or barely chilled cake will be runny and messy instead of dense and gooey.

    If Slices are runny and messy instead of dense and gooey.:

    Refrigerate overnight (at least 8 hours) before slicing.

    If Ragged, crumbly slices with berry smear on the edges.:

    Slice with a sharp knife, wiping the blade clean between cuts; a slightly warm blade gives the cleanest edges.
