HOW TO MAKE 3 INGREDIENT BROWNIES


Note: Please scroll to the full printable recipe card at the bottom for ingredient quantities and the method

Preheat your oven to 180°C / 350°F.

Mash the bananas in a bowl until smooth. The riper they are, the sweeter your brownies will be.

Stir in the peanut butter (or nut butter of choice) until fully combined.

Add the cocoa powder and mix until you have a smooth, thick batter.

Pour into a lined or greased baking tin.

Bake for 20 minutes, or until a skewer inserted in the center comes out clean.

Allow to cool before slicing (this helps them firm up).

ADD-IN IDEAS

🍫 Chocolate chips – Add ¼–½ cup to the batter or sprinkle on top before baking. Easiest and most effective option.

🍯 Honey or maple syrup drizzle – Drizzle over the top after baking for extra sweetness.

🍌 Extra ripe bananas – The darker and spottier, the sweeter your brownies.

🌴 Coconut sugar or granulated sugar (1–2 tbsp) – Mix into the batter for a sweeter, richer flavor.

For extra indulgence, stir in dark chocolate chips.

Almond butter or cashew butter works beautifully if you want a peanut-free option.

Let them cool completely for a fudgier texture.
