Ingredients You’ll Need

You only need three simple ingredients:

Bananas (very ripe—the spottier, the better!)
Almond butter (or any nut or seed butter—peanut butter is delicious)
Cocoa or cacao powder

Optional Add-Ins

Want to elevate the flavor? Try adding:

Dark or unsweetened chocolate chips
Pure vanilla extract
Maple syrup or raw honey (for extra sweetness)
Salt (to enhance the chocolate flavor)

Favorite Chocolate Brands

I use dairy-free and refined sugar-free chocolate in my recipes and specifically love using brands like Hu Kitchen and Navitas. Many other brands now make dairy-free, refined sugar-free chocolate as well, which is amazing!

How to Make These Brownies Nut-Free

To make this recipe completely nut-free, simply swap the almond butter for a seed-based alternative. The best option is sunflower seed butter, which has a similar texture and works as a 1:1 replacement.

Nut-free options:

Sunflower seed butter (best overall substitute)
Tahini (for a slightly more savory flavor)
Pumpkin seed butter

Keep in mind that sunflower seed butter can sometimes react with cocoa powder and turn slightly green as it bakes—this is completely harmless and doesn’t affect the taste!

If your seed butter is unsweetened, you may want to add a little maple syrup or honey to maintain the brownies’ natural sweetness.

Recipe Steps

This is just an overview, you can find the full recipe below.

Mash the ripe bananas in a bowl until smooth.
Stir in the almond butter and cocoa powder until fully combined.
Mix in any optional add-ins, if using.
Pour the batter into the pan and spread evenly. Bake until set.
Let cool completely before slicing and serving.
