Can I make these brownie bars without protein powder?

Protein powder plays an important role in the recipe, so leaving it out will change the texture and protein content. You would likely need to adjust the dry and wet ingredients rather than simply omitting it.

Why are my protein brownies dry?

Overbaking is one of the most common reasons protein brownies turn out dry. Protein powder can also absorb quite a bit of moisture, and different brands behave differently. Start checking the brownies around 18 minutes and remove them when the edges are set but the center still looks slightly soft.

Can I use vanilla protein powder?

Yes. Vanilla protein powder can be used, although the chocolate flavor won't be quite as strong. I would add an extra tablespoon of unsweetened cocoa powder if you want a deeper chocolate taste.

Can I use cottage cheese instead of Greek yogurt?

You can experiment with blended cottage cheese, but it may produce a slightly different texture. Blend it until completely smooth before adding it to the wet ingredients.

How do I get cleaner brownie slices?

Cool the brownies completely first, then refrigerate them for at least 30 minutes. Use a sharp knife and wipe it clean between cuts.

Can I freeze high-protein brownie bars?

Yes. Wrap individual bars and freeze them in an airtight freezer-safe container for up to 2 months. Thaw them in the refrigerator before serving.

1 teaspoon baking powder
1/4 teaspoon salt

Instructions

Preheat the oven to 350°F. Line an 8-inch square baking pan with parchment paper.
Blend the oats until finely ground and similar in texture to flour.
Whisk the oat flour, protein powder, cocoa powder, baking powder, and salt together in a large bowl.
In another bowl, whisk the Greek yogurt, eggs, maple syrup, vanilla, and 2 tablespoons of milk until smooth.
Add the wet mixture to the dry ingredients and stir until just combined. Add the remaining tablespoon of milk only if the batter is too thick to spread easily.
Fold in most of the chocolate chips.
Spread the batter evenly into the prepared pan and sprinkle the remaining chocolate chips over the top.
Bake for 18–22 minutes, until the edges are set and the center remains slightly soft.
Cool completely in the pan. For firmer bars, refrigerate for at least 30 minutes before slicing.
Cut into 12 bars and serve.

Notes

Protein powders vary considerably in sweetness and liquid absorption. If your batter is unusually thick, add milk gradually rather than all at once.

Store the bars in an airtight container in the refrigerator for up to 5 days. They can also be individually wrapped and frozen for up to 2 months.

Nutrition information will vary depending on the brands, substitutions, and serving size used.

These high protein brownie bars are a practical way to keep a chocolate snack ready when you need one. Make a batch, let them cool completely, slice them into portions, and keep them refrigerated for an easy treat throughout the week.
