Flourless Fudgy Low-Calorie Brownies (Made with Bananas & Peanut Butter)

Every now and then you just need chocolate. Not a square. Not a bite. A proper fudgy brownie.

But if you're like me, you also want to enjoy dessert without feeling like you just derailed your entire week. That’s exactly how these brownies were born.

I was inspired by a few videos I came across online and decided to tweak the recipe slightly to better suit a larger family (because in this house, if I make a small batch… it disappears in 4.7 seconds).

These brownies are:

✔ Flourless ✔ Naturally sweetened mostly with bananas ✔ Rich and fudgy ✔ Simple ingredients ✔ Kid and family approved

Now listen — I’m not calling these flourless brownies the healthiest dessert on the planet. They’re still a treat. But they’re a lower-calorie, more wholesome option when you want something sweet without going overboard.

And the texture? Super moist. Deep chocolate flavor. Soft and fudgy inside. Honestly, we devoured them.

Flourless Fudgy Low-Calorie Brownies Ingredients

• 5 ripe bananas (the riper, the better — brown spots = more sweetness)

• 3/4 cup peanut butter(You can substitute with almond butter, cashew butter, or any nut/seed butter)

• 6½ tablespoons unsweetened cocoa powder

• 3/4 cup dark chocolate chips(You can reduce or omit for a lower sugar version)

Makes: 12 servings

Instructions

• Preheat oven to 350°F (175°C).

• Line a square baking pan (8x8 works well - you can opt for a larger pan for thinner brownies) with parchment paper

• In a large bowl, mash the bananas until smooth.

• Add the peanut butter and mix until fully combined.

• Stir in the unsweetened cocoa powder until the batter is rich and chocolatey.

• Fold in the dark chocolate chips.

• Pour the batter into your prepared pan and smooth the top.

• Bake for 30–35 minutes, or until set but still slightly soft in the center.

• Let cool before slicing — they firm up as they cool and get even fudgier.

Why These Flourless Brownies Are a Lighter Treat

Instead of flour, oil, and refined sugar, this recipe uses:

• Bananas for natural sweetness and moisture

• Nut butter for healthy fats and protein

• Cocoa powder for deep chocolate flavor without added sugar

You still get that indulgent brownie experience — just with more nutrient-dense ingredients. Tips & Variations

• Lower sugar: Reduce or skip the chocolate chips

• Nut-free: Use sunflower seed butter

• Extra indulgent: Sprinkle a few chips on top before baking

• Meal prep win: Store in the fridge — they get even fudgier the next day
  

These flourless brownies are perfect for when you want something sweet after dinner, to tuck into lunchboxes, or to have with a cup of tea when the craving hits. A treat you can enjoy without the full-on sugar crash? Yes please.

If you try them, let me know — because in this house, they’re already on repeat.
