Why These 3 Ingredient Banana Brownies Work So Well

Each ingredient plays a critical role in the final texture and flavor.

Ripe bananas act as both the sweetener and moisture source. Their natural sugars enhance the chocolate flavor while their soft texture helps bind the batter together.

Peanut butter replaces traditional structural ingredients like flour and eggs. Its natural oils and proteins help the brownies hold their shape while creating a dense, fudgy consistency.

Cocoa powder provides pure chocolate intensity without needing melted chocolate. It blends easily into the batter and creates the rich flavor expected from traditional brownies.

This combination creates healthy banana brownies with 3 ingredients that feel indulgent while using only simple whole-food ingredients.

Step-by-Step Instructions

1. Prepare the pan

Preheat your oven to 350°F (175°C). Line a small baking pan with parchment paper.

2. Mash the bananas

In a bowl, mash the bananas until smooth. Small lumps are fine, but the mixture should be mostly uniform.

3. Mix in the peanut butter

Add peanut butter and stir until fully combined. The mixture will become thick and creamy.

4. Add cocoa powder

Mix in cocoa powder slowly, folding until the batter becomes smooth and evenly chocolate-colored.

5. Transfer and bake

Spread the batter evenly in your prepared pan. Add chocolate chips on top if desired.

Bake for 18–22 minutes, until the edges are set and the center is slightly soft.

6. Cool before slicing

Allow the brownies to cool for at least 15 minutes. This helps them firm up and improves texture.

These 3 ingredient banana peanut butter brownies come together quickly using only one bowl.

Texture: What to Expect

These brownies have a dense, fudgy interior rather than a cake-like crumb.

Why Peanut Butter Makes These Brownies Better

Peanut butter plays a critical structural role in these banana peanut butter brownies with 3 ingredients.

It provides:

• binding strength
• creamy consistency
• healthy fats and protein that help improve texture and structure
• improved texture
• enhanced flavor depth

Without peanut butter, the brownies would lack stability and richness.

Both natural and regular peanut butter work, but smooth varieties produce the best texture.

Common Mistakes to Avoid
