Ingredients
Method
- Preheat oven to 350°F (175°C). Grease and flour a 9x13 inch baking pan.
- Whisk together almond flour, coconut flour, whey protein powder, baking powder, and salt in a medium bowl.
- Cream softened butter and granular sweetener in a large bowl until light and fluffy (3-4 minutes). Beat in eggs one at a time, then stir in vanilla extract.
- Gradually add dry ingredients to wet, mixing until just combined. Gently fold in whipping cream.
- Pour batter into the prepared pan and bake for 30-35 minutes, or until a skewer comes out clean.
- While cake bakes, prepare the glaze: melt 1/2 cup butter with 1/2 cup granular sweetener and 1/4 cup water. Simmer for 2 minutes, then stir in 1 tsp vanilla extract.
- Immediately poke holes in the warm cake with a skewer. Pour hot glaze evenly over the cake and let it soak in. Cool completely before serving.
Notes
- For the moistest keto butter cake, ensure your butter and eggs are at room temperature before mixing. This helps create a smooth, emulsified batter that bakes evenly.
- Don't overmix the batter once the dry ingredients are added; mix until just combined to prevent a tough cake.
- When poking holes in the warm cake for the glaze, make them deep enough to allow the butter mixture to penetrate fully, but not so wide that the cake crumbles. Aim for a skewer or chopstick size. - Store leftover cake covered at room temperature for up to 3 days, or refrigerate for up to a week. For longer storage, freeze individual slices for up to 2 months. Nutrition information is an estimate, calculated automatically. Values vary with brands, substitutions and portion sizes.
