Ingredients:
For the filling:
- 2 cups fresh or frozen blueberries
- 1 tbsp lemon juice
- 2 tbsp powdered erythritol (or your favorite keto sweetener)
- 1/2 tsp xanthan gum (for thickening – optional)
For the topping:
- 3/4 cup almond flour
- 2 tbsp coconut flour
- 1/4 cup powdered erythritol
- 1 tsp baking powder
- 1/4 tsp salt
- 1/4 cup melted butter
- 1 egg
- 1/2 tsp vanilla extract
🔪 Instructions:
- Preheat oven to 350°F (175°C).
- Prepare filling: In a mixing bowl, toss blueberries with lemon juice, sweetener, and xanthan gum (if using). Spread evenly in a greased 8×8 baking dish or small oven-safe skillet.
- Make the topping: In another bowl, mix almond flour, coconut flour, erythritol, baking powder, and salt. Stir in melted butter, egg, and vanilla until a thick batter forms.
- Assemble: Drop spoonfuls of topping over the blueberries. It doesn’t need to cover fully – it’ll spread as it bakes.
- Bake for 25–30 minutes or until the top is golden and the berries are bubbly.
- Cool slightly before serving. Enjoy warm—great with a scoop of keto vanilla ice cream or whipped cream!
