Banana Pudding Cake
Southern Banana Pudding Cake
Low-Carb • Sugar-Free • Keto-Friendly
Soft vanilla cake is layered with silky sugar-free custard and crunchy homemade keto wafers for a classic banana-pudding-inspired dessert without the added sugar.
🍰 Cake
Ingredients
- 1½ cups almond flour
- ¼ cup coconut flour
- ½ cup monk fruit/allulose sweetener
- 1½ tsp baking powder
- ¼ tsp salt
- 4 large eggs
- ½ cup unsalted butter, melted
- ½ cup unsweetened almond milk
- 2 tsp vanilla extract
- ½ tsp banana extract, optional
Directions
- Preheat oven to 175°C / 350°F. Line an 8-inch square baking pan with parchment and lightly grease it.
- Whisk almond flour, coconut flour, baking powder, sweetener, and salt.
- In another bowl, whisk eggs, melted butter, almond milk, vanilla, and banana extract.
- Combine the wet and dry ingredients until a smooth batter forms. Let it sit for 2–3 minutes so the coconut flour can absorb some moisture.
- Spread evenly in the pan.
- Bake for 20–25 minutes, or until the center is set and a toothpick comes out clean.
- Cool completely before assembling.
🍮 Sugar-Free Vanilla Custard
Ingredients
- 2 cups unsweetened almond milk
- 3 large egg yolks
- ¼ cup monk fruit/allulose sweetener
- 2 tbsp cornstarch for a lower-carb version, use 1½ tbsp xanthan gum-free keto pudding thickener or a suitable low-carb pudding mix
- 1 tbsp butter
- 2 tsp vanilla extract
- Pinch of salt
Directions
- Whisk egg yolks, sweetener, and thickener in a bowl.
- Heat almond milk in a saucepan over medium heat until steaming but not boiling.
- Slowly whisk some warm milk into the egg mixture to temper it.
- Pour everything back into the saucepan.
- Cook over medium-low heat, whisking constantly, until thick and creamy.
- Remove from heat and stir in butter, vanilla, and salt.
- Cover the surface directly with plastic wrap and chill until completely cool.
🍪 Homemade Keto Vanilla Wafers
Ingredients
- ½ cup almond flour
- 2 tbsp coconut flour
- 2 tbsp powdered monk fruit/allulose
- 1 tbsp melted butter
- 1 egg white
- ½ tsp vanilla extract
- ¼ tsp baking powder
- Pinch of salt
Directions
- Heat oven to 175°C / 350°F.
- Mix all ingredients into a soft dough.
- Roll or press the dough very thin between two sheets of parchment.
- Cut into small circles or squares.
- Bake for 7–10 minutes, watching carefully because the wafers are thin.
- Cool completely; they will become crisp as they cool.
🍌 Optional Banana Layer
For a strict keto version, skip real banana and use banana extract in the cake and custard.
For a less strict low-carb version, add a very thin layer of sliced banana between the cake and custard.
🥄 Assembly
- Cut the cooled cake into small squares.
- Place half of the cake pieces in the bottom of a serving dish.
- Spread over half of the chilled vanilla custard.
- Add a layer of keto wafers.
- Repeat with the remaining cake and custard.
- Crush a few extra wafers over the top.
- Refrigerate for at least 3–4 hours, preferably overnight, so the cake can absorb some of the creamy custard.
- Serve chilled.
✨ Optional Topping
Top with:
- Sugar-free whipped cream
- A sprinkle of crushed keto wafers
- A tiny drizzle of sugar-free caramel sauce
Storage: Refrigerate covered for up to 3 days. Keep the wafers separate if you want them to stay extra crunchy.
Note: For a truly keto version, use a low-carb thickener rather than regular cornstarch and omit the real banana. Monk fruit/allulose is especially useful here because allulose helps the custard and cake stay softer.
