Ingredients
Instructions
- Preheat and prep. Preheat oven to 350°F (175°C). Line an 8×8-inch pan with parchment.
- Mix the dry ingredients. Whisk almond flour, cocoa, protein powder, sweetener, baking powder, and salt in a bowl.
- Add the wet ingredients. Stir in eggs, melted butter, almond milk, and vanilla until a thick batter forms. Fold in the chopped walnuts.
- Bake. Spread the batter in the pan. Bake 20–25 minutes until the center is just set. Cool completely in the pan.
- 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.
Notes & 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.
Variations & serving ideas
- 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.
- Peanut butter swirl: Drop spoonfuls of sugar-free peanut butter on the batter and swirl before baking.
- Espresso walnut: Add 1 tsp espresso powder to the dry ingredients for a deeper chocolate flavor.
- Double chocolate: Fold extra sugar-free chocolate chips into the batter.
- Frosted squares: Skip the glaze and frost with a cream cheese chocolate frosting instead.
Storage

Frequently asked questions
Are these brownies keto-friendly?
Yes. At only 5g net carbs per brownie they fit most keto and low-carb plans.
Why are my brownies dry?
They were overbaked. Pull them when the center is just set so they stay fudgy.
Can I skip the protein powder?
Yes. Replace it with extra almond flour. The brownies will be a little lower in protein.
Do I have to glaze them?
No. They are still good plain, but the glaze gives that bakery-style finish.
Can I freeze them?
Yes. Freeze cut squares for up to 2 months and thaw in the refrigerator.
What protein powder works best?
A chocolate whey or whey-casein blend gives the fudgiest texture. Plant protein can make them a bit drier.
