Keto Butter Sponge Cake (Square Pan Style)
📝 Ingredients
Dry Ingredients
2 cups almond flour
2 tbsp coconut flour
2 tsp baking powder
¼ tsp salt
Wet Ingredients
½ cup unsalted butter (melted, cooled slightly)
4 large eggs (room temperature, separated)
½ cup erythritol or monk fruit sweetener
1 tsp vanilla extract
½ cup unsweetened almond milk
👩🍳 Instructions
1. Prep the Pan
Preheat oven to 350°F (175°C).
Grease and line an 8-inch square cake pan with parchment paper.
2. Mix Dry Ingredients
In a bowl, whisk almond flour, coconut flour, baking powder, and salt.
3. Prepare Egg Yolks Mixture
In another bowl, whisk egg yolks with melted butter, sweetener, vanilla, and almond milk until smooth.
Add the dry ingredients and mix until combined.
4. Whip Egg Whites
In a separate clean bowl, beat egg whites with a pinch of salt until stiff peaks form.
Gently fold the egg whites into the batter to keep it airy and sponge-like.
5. Bake
Pour batter into the prepared square pan and smooth the top.
Bake for 25–30 minutes, or until a toothpick comes out clean.
Let cool completely before slicing.
