Ingredients
- Cinnamon Filling:
- 3 tablespoons granulated sweetener (erythritol or allulose)
- 2 teaspoons ground cinnamon
- Cake:
- 3 cups almond flour (336 g)
- 1/2 cup erythritol sweetener (100 g)
- 1/4 cup unflavored whey protein powder (27 g)
- 2 teaspoons baking powder
- 1/2 teaspoon salt
- 3 large eggs
- 1/2 cup melted butter (113.5 g)
- 1/2 teaspoon vanilla extract
- 1/2 cup almond milk or water (118.29 ml)
- 1 tablespoon melted butter (for brushing top)
- Cream Cheese Frosting:
- 1 1/2 ounces softened cream cheese (44.13 g)
- 2 tablespoons powdered sweetener (erythritol or allulose)
- 1 tablespoon heavy whipping cream
- 1/2 teaspoon vanilla extract
Instructions
- In a small bowl, mix the cinnamon and granulated sweetener. Set aside.
- Preheat oven to 325ºF and grease a 9×9-inch baking pan.
- In a medium bowl, whisk together the almond flour, erythritol, protein powder, baking powder, and salt.
- Stir in the eggs, melted butter, and vanilla extract. Add almond milk or water, mixing until smooth.
- Spread half the batter into the prepared pan. Sprinkle two-thirds of the cinnamon mixture over the batter.
- Spread the remaining batter on top and smooth with a spatula.
- Bake for 25–30 minutes, or until the top is golden and firm to the touch.
- Remove from oven, brush with melted butter, and sprinkle with the remaining cinnamon mixture. Let cool completely.
- To make the frosting, beat the softened cream cheese until smooth. Add powdered sweetener, heavy cream, and vanilla extract, and beat until well combined.
- Pipe or drizzle the frosting over the cooled cake before serving.
Notes
- Store leftovers in an airtight container in the fridge for up to 5 days.
- For a dairy-free version, substitute butter and cream cheese with plant-based alternatives.
- Let the cake cool completely before frosting to prevent melting.
- Use a sugar-free maple glaze instead of cream cheese for variation.
