Key element — grease the pan well
A bundt pan has lots of corners. Grease every ridge thoroughly (or use a baking spray with flour) so the cake releases cleanly.
Ingredients
Cake batter
- 2 cups almond flour
- ½ cup unsweetened cocoa powder
- ½ cup chocolate or unflavored protein powder
- ½–⅔ cup powdered sugar-free sweetener
- 2 tsp baking powder
- ½ tsp salt
- 4 large eggs
- ½ cup melted butter or coconut oil
- ½ cup unsweetened almond milk or cream
- 1 tsp vanilla extract
- Optional: ¼ cup sugar-free chocolate chips
Chocolate glaze
- 3 oz sugar-free dark chocolate, melted
- 2–3 Tbsp heavy cream or coconut cream
- Optional: 1 tsp powdered sweetener
Swaps
- Higher protein: Add an extra scoop of protein powder and a splash more milk if needed.
- Dairy-free: Use coconut oil, almond milk, and dairy-free chocolate.
- No bundt pan: Bake in a loaf pan or 8-inch round (adjust bake time).
- Extra chocolate: Fold in sugar-free chips or drizzle extra glaze.
Instructions
| 1 | Preheat and prep. Preheat oven to 350°F (175°C). Thoroughly grease a 8–10 cup bundt pan, getting into every ridge. |
| 2 | Mix dry ingredients. In a large bowl, whisk together almond flour, cocoa powder, protein powder, powdered sweetener, baking powder, and salt. |
| 3 | Add wet ingredients. Stir in the eggs, melted butter or oil, almond milk or cream, and vanilla until just combined. Fold in chocolate chips if using. Do not overmix. |
| 4 | Bake. Spoon the batter into the prepared pan and smooth the top. Bake 40–50 minutes until a toothpick inserted in the center comes out with a few moist crumbs. Cool in the pan 15 minutes, then invert onto a rack and cool completely. |
| 5 | Glaze. Melt the sugar-free chocolate with cream until smooth. Spoon or drizzle over the cooled cake and let it set before slicing. |
Pro tips
- Grease the bundt pan thoroughly so the cake releases in one piece.
- Don’t overbake — a few moist crumbs on the toothpick keep the crumb tender.
- Cool completely before glazing so the chocolate doesn’t slide off.
- Use powdered sweetener for a smoother cake texture.
- This cake slices cleaner after it has fully cooled or chilled slightly.
