There I was, staring into the fridge like it held the secrets of the universe. The kids were bouncing off the walls, and I needed something sweet, fast.

Why You'll Love This Recipe
About the Ingredients
1 1/2 cups (180g) all-purpose flour
The base of the dessert. You can swap in whole wheat flour for a nuttier flavor, but the texture will be denser.
1 cup (200g) granulated sugar
Adds sweetness. Brown sugar works too, giving a deeper molasses note.
1/2 cup (120g) unsalted butter, melted
Use salted butter if that's all you have—just skip the added salt in the recipe.
1 large egg
Binds everything together. For a vegan version, use a flax egg (1 tbsp ground flax + 3 tbsp water).
1 teaspoon baking powder
Helps the dessert rise. Make sure it's fresh or it'll fall flat.
1/2 teaspoon salt
Balances the sweetness. If using salted butter, reduce to 1/4 tsp.
2 ripe bananas, mashed (about 1 cup)
Adds moisture and natural sweetness. The riper, the better—brown spots are perfect.
1/2 cup (120g) peanut butter
Creamy or chunky both work. Almond butter is a tasty swap.
1 teaspoon vanilla extract
Enhances flavor. Skip it if you're out, but it's worth the splash.
1/2 cup (60g) chopped nuts or chocolate chips (optional)
Adds crunch or melty goodness. Use whatever you have—walnuts, pecans, or dark chocolate chips.
Tips & Tricks
Don't overmix the batter
Overmixing develops gluten, making the dessert tough. Stir just until combined.
Use ripe bananas
The browner the better—they mash easier and add more sweetness.
Line your baking dish with parchment
This prevents sticking and makes cleanup a breeze.
Pro Tips
Step-by-Step Instructions
1. Preheat oven
Set your oven to 350°F (175°C). Grease an 8×8-inch baking dish or line with parchment paper.
2. Mix dry ingredients
In a medium bowl, whisk together flour, baking powder, and salt. Set aside.
3. Combine wet ingredients
In a large bowl, mix melted butter and sugar until smooth. Beat in the egg, then add mashed bananas, peanut butter, and vanilla. Stir until well combined.
4. Fold in dry ingredients
Gradually add the dry mixture to the wet, folding gently with a spatula. Stop as soon as no flour streaks remain.
5. Add optional extras
Fold in chopped nuts or chocolate chips if using. Reserve a few to sprinkle on top for looks.
6. Pour into dish
Transfer the batter to your prepared dish and spread evenly. Sprinkle the reserved nuts/chips on top.
7. Bake until golden
Bake at 350°F (175°C) for 25-30 minutes, or until the top is golden brown and a toothpick inserted in the center comes out clean. The edges should pull slightly from the sides.
8. Cool and serve
Let it cool in the pan on a wire rack for at least 10 minutes. Slice into squares and serve warm or at room temperature.
Delicious Variations
- Swap peanut butter for Nutella for a chocolate-hazelnut twist.

Frequently Asked Questions

Yes, use a 1:1 gluten-free flour blend. The texture will be slightly crumblier, but it works.
