Why You’ll Love Protein Brownies

These Protein Brownies are the perfect treat—healthy, free of added sugar, yet rich and satisfying. Keep in mind that these brownies are not as sweet as regular brownies, so don’t expect the same sugar rush you’re used to 🫨. The sweetness comes solely from the bananas 🍌, which makes these brownies a guilt-free delicious option, far from those overly “healthy” treats you dodge at a potluck. More importantly, the added protein is undetectable, so you don’t have to worry about a gritty or grainy texture. Trust me, unlike your ex, these Protein Brownies will have you weak in the knees for all the right reasons 😜.

How to Prepare

🌡️ Preheat oven to 350F (175C).

🍌 Add the peeled, ripe bananas to a mixing bowl and mash with a fork.

🥜 Add in the nut (or seed) butter and stir.

🍫 Then add in the unsweetened cacao and protein powder and stir together.

🤎 Pour batter into a parchment paper-lined 8×8 baking dish. (Optionally, top with chocolate chips before baking).

😋 Bake for 15-20 minutes, cool, slice and enjoy!

Nonna’s Tip 🍌

If your bananas are super ripe, I find that this recipe doesn’t need any added sweetener at all!

Variations and Substitutions for Protein Brownies

  1. Experiment with a different 🥜 nut or seed butters like almond butter, cashew butter, or sunflower seed butter.
  2. For a sweeter brownie, you could add sweeteners such as 🍯 honey, maple syrup, or agave syrup.
  3. Change up the flavor of your Protein Brownies with spices like cinnamon, nutmeg, or even a pinch of 🧂 salt.
  4. Have fun with some toppings: chocolate chips (white or dark), 🥥 coconut flakes, or even chopped candy canes for a holiday treat.
  5. For a soft and gooey consistency, feel free to under-bake it a bit!

Nutritional Highlights

These Protein Brownies seriously feel like an ooey, gooey indulgent brownie, but they’re sooooo not. Each brownie has 7 grams of protein thanks to the protein powder and nut butter, PLUS, there’s absolutely no refined sugar: just super ripe and sweet bananas and optionally maple syrup if you need a little more. These are also only 137 calories per square (which are pretty generously-sized IMO!), and are gluten- and dairy-free.

This is the perfect little bite when you need a pick-me-up in the afternoon but do not want to lose sight of your goals for the day. Satisfying, guilt-free, and really delicious!

Best Served With

  • Serve by Protein Brownies for dessert with a scoop of vanilla 🍨 ice cream or my delicious Cottage Cheese Ice Cream.
  • A dollop of whipped cream.
  • Some fresh fruit such as strawberries, raspberries, or 🫐 blueberries.
  • A glass of 🥛 milk.

Common Questions

do I have to use maple syrup in this protein brownies recipe?

Not at all! If you’d like to add a little sweetness you can add it in (or honey or agave syrup instead), otherwise totally omit it.

can I use frozen bananas in this recipe?

Yes, you can use frozen bananas. Just make sure to thaw and drain any excess liquid before mashing them.

Can I use a baking dish of another size instead of 8×8?

Yes, you can use something smaller for thicker brownies, but you may have to extend the cooking time.

how can I tell if the brownies are cooked?

Insert a toothpick into the center of the brownies and then if it comes out clean or with a few moist crumbs, they are done. If it comes out with wet batter, they need more time.

what if I don’t have parchment paper?

You can grease the pan with butter or cooking spray, but parchment paper helps to prevent sticking and makes cleanup easier.

Hi! I'm Sneji. Nice to meet you!

I am more commonly known as “The Modern Nonna” on social media where I create easy home cooked meals with a modern twist. I was born and raised in Sofia, Bulgaria and learned how to cook at the best culinary school in the world – my grandma’s kitchen. I lived in Greece on the Island of Crete with my parents for a while and then moved to Toronto, Canada when I was in grade 5. I started to really cook and experiment with food 11 years ago when I was 21 years old. Everything I currently know is a reflection of some part of my life…
