🛒 Ingredients (Makes 12–14 cookies)
-
1 box (about 18 oz / 500 g) brownie mix
-
1 scoop (25–30 g) chocolate or vanilla protein powder
-
2 large eggs
-
¼ cup (60 ml) oil or melted butter
-
2–3 tablespoons milk (as needed)
Optional add-ins:
-
¼ cup dark chocolate chips
-
2 tablespoons peanut butter
-
Chopped walnuts
👩🍳 Instructions
1️⃣ Preheat
Preheat oven to 350°F (175°C). Line a baking sheet with parchment paper.
2️⃣ Mix the Dough
In a large bowl:
-
Combine brownie mix and protein powder.
-
Add eggs and oil.
-
Mix until thick and glossy.
If the dough feels too dry (protein powder can thicken it), add 1–2 tablespoons milk until it reaches a thick cookie-dough consistency.
3️⃣ Shape
Scoop tablespoon-sized portions onto the baking sheet.
Leave space between cookies — they will spread slightly.
For thicker cookies, gently press the tops flat.
4️⃣ Bake
Bake for 9–11 minutes.
The centers should look slightly soft — they will firm up as they cool.
5️⃣ Cool
Let cookies cool on the tray for 5 minutes before transferring to a rack.
They become perfectly chewy as they set.
🍫 Texture Tips
-
Underbake slightly for fudgier cookies.
-
For cakier texture, bake 1–2 minutes longer.
-
Use whey-casein blend protein for best texture.
Avoid using only plant protein unless you add a little extra moisture.
