Melt-In-Your-Mouth Apple “Pie” Cake
This viral, melt-in-your-mouth apple bake bridges the gap between a classic pie, a dense cake, and a rich custard. Rather than fussing with rolling out pie dough, this recipe utilizes a thin, crepe-like batter that is poured directly over heavily diced apples in a square baking pan. As it bakes, the batter transforms into a sweet, custardy binder that holds the soft, juicy apple pieces together. Because the apples are left unpeeled, they add beautiful little pops of red color and texture throughout the soft squares. Finished with a dusting of powdered sugar, it is an incredibly simple, elegant, and crowd-pleasing dessert.

The Ingredients
The Apples:
-
4 medium apples (approx. 500 g), chopped into small dice, unpeeled (Gala, Fuji, or Honeycrisp work beautifully)
The Custard Batter:
-
3 large eggs
-
180 ml (3/4 cup) milk (whole milk preferred)
-
150 g (3/4 cup) granulated sugar
-
60 g (1/4 cup) unsalted butter, melted and slightly cooled
-
1 tsp vanilla extract
-
150 g (1 1/4 cups) all-purpose flour
-
1 tbsp (15 g) baking powder
-
A pinch of salt
-
Powdered sugar for dusting
Step-by-Step Instructions
-
Prep the Oven and Pan: Preheat your oven to 350°F (180°C). Grease an 8×8-inch square springform pan or baking dish and line the bottom with parchment paper.
-
Mix the Wet Ingredients: In a large mixing bowl, vigorously whisk the eggs, granulated sugar, and salt together for about 2 minutes until pale and frothy. Whisk in the milk, melted butter, and vanilla extract until completely combined.
-
Add the Dry Ingredients: Sift the all-purpose flour and baking powder directly into the wet mixture. Gently whisk until the batter is smooth and free of any large lumps. The batter will be quite thin, similar to pancake batter.
-
Fold in the Apples: Add the diced, unpeeled apples directly into the batter. Use a rubber spatula to fold them in until every apple piece is coated.
-
Pour and Bake: Pour the entire mixture into your prepared square baking pan, using your spatula to gently press the apples down into an even layer.
-
Bake: Bake in the center of the oven for 40 to 45 minutes, or until the top is deeply golden brown and a toothpick inserted into the center comes out clean.
-
Cool and Garnish: Let the cake cool in the pan for at least 20 minutes before releasing the springform clasp or slicing. Dust generously with powdered sugar just before serving.
Pro Tips for the Best Results
-
The Cut Matters: Dice your apples relatively small (about 1/2-inch pieces) as seen in the batter. If the chunks are too large, the cake will not hold its shape when sliced, and the texture won’t be as melt-in-your-mouth soft.
-
Don’t Overmix: Once you add the flour, whisk just until the streaks of flour disappear. Overmixing will develop the gluten and make the custardy base rubbery instead of tender.
-
Serve Warm or Chilled: This dessert is fantastic served slightly warm with a scoop of vanilla bean ice cream, but it is equally delicious served chilled straight from the fridge the next day, as the custard sets up even more firmly.
Recipe Notes
-
Pan Size: A square pan yields the beautiful, thick geometric slices shown in the finished bake. If you only have a 9-inch round pan, you can use it, but the slices will be slightly thinner wedge shapes.
-
Storage: Because of the high moisture content and custardy texture, store any leftovers in an airtight container in the refrigerator for up to 4 days.

Health & Dietary Benefits
-
High Apple-to-Batter Ratio: This recipe uses a massive amount of fresh fruit relative to the amount of flour and sugar, making it significantly lighter than a traditional butter-heavy pie crust or dense pound cake.
-
Fiber and Nutrients: By leaving the skins on the diced apples, you retain the majority of the fruit’s natural fiber, vitamins, and antioxidants, which are concentrated in the peel.
-
Calcium and Protein: The addition of whole milk and three whole eggs provides a modest but helpful boost of calcium and satiating protein.
Frequently Asked Questions (Q&A)
Can I peel the apples if I prefer? Yes. While leaving the skins on provides a lovely red color contrast and saves prep time, you can absolutely peel the apples if you prefer an entirely uniform, ultra-soft texture throughout the cake.
Why is my batter so liquidy? Do not panic! The batter for this specific type of cake is supposed to be very thin. It is designed to seep into all the crevices between the diced apples. As it bakes, the flour and eggs will set up into a soft, firm custard that binds the fruit perfectly.
Can I add spices to this recipe?
Absolutely. While the vanilla highlights the pure, buttery apple flavor, adding 1 teaspoon of ground cinnamon and a dash of nutmeg to the dry ingredients will give this dessert a classic, cozy, warm autumn flavor profile.
