Key element — don’t overbake
Pull the brownies when the center is just set. Overbaking dries them out and makes them cakey instead of fudgy.
Ingredients
Brownies
- 1 cup almond flour
- ⅓ cup unsweetened cocoa powder
- ⅓ cup chocolate or unflavored protein powder
- ½ cup powdered sugar-free sweetener
- 1 tsp baking powder
- ¼ tsp salt
- 2 large eggs
- ⅓ cup melted butter or coconut oil
- ¼ cup unsweetened almond milk
- 1 tsp vanilla extract
- ½ cup chopped walnuts, plus extra for topping
Chocolate glaze
- ⅓ cup sugar-free chocolate chips
- 1 Tbsp butter or coconut oil
- 1–2 Tbsp heavy cream (as needed)
- Extra chopped walnuts for garnish
Swaps
- Nut-free: Use sunflower seed flour and skip the walnuts.
- Higher protein: Add an extra tablespoon of protein powder and a splash more milk.
- Pecan brownies: Swap walnuts for pecans.
- Extra fudgy: Stir in 2 Tbsp cream cheese with the wet ingredients.
Instructions
| 1 | Preheat and prep. Preheat oven to 350°F (175°C). Line an 8×8-inch pan with parchment. |
| 2 | Mix the dry ingredients. Whisk almond flour, cocoa, protein powder, sweetener, baking powder, and salt in a bowl. |
| 3 | Add the wet ingredients. Stir in eggs, melted butter, almond milk, and vanilla until a thick batter forms. Fold in the chopped walnuts. |
| 4 | Bake. Spread the batter in the pan. Bake 20–25 minutes until the center is just set. Cool completely in the pan. |
| 5 | Glaze and slice. Melt chocolate chips with butter and a splash of cream until smooth. Spread over the cooled brownies, sprinkle with walnuts, and let the glaze set. Cut into 12 squares. |
Pro tips
- Don’t overbake — fudgy brownies come out when the center is just set.
- Cool completely before glazing so the chocolate doesn’t melt off.
- A warm knife makes cleaner slices.
- If the batter is too thick, add a splash more almond milk.
- These taste even better the next day after the texture settles.
