Peanut Butter Banana Blondies

These mouth-watering peanut butter banana blondies are vegan, gluten-free, and oil-free. They’re easy to make, freezer-friendly, and nutritious.

These treats are a delicious plant-based dessert or snack. You can make these in advance and store them in an airtight container for up to five days or freeze them for up to six months.

Main ingredients & substitutions

Bananas are the star ingredient of these vegan blondies. Be sure to choose bananas that have plenty of brown spots so you’ll know they’re ripe enough. If you use bananas that are under ripe the end results won’t be as sweet.

I used coconut flour in this recipe because I wanted these blondies to be grain-free and high fiber. Coconut flour is available at many grocery stores these days or you can order it online.

These blondies are sweetened with maple syrup, but you can substitute honey if you prefer (and if you don’t need these to be strictly vegan). I prefer to use maple syrup because it adds a relatively neutral sweetness that doesn’t overpower the flavor of the bananas in this recipe.

This recipe calls for natural smooth peanut butter. Be sure to use peanut butter that doesn’t contain any added sugar or salt. The only ingredient on the jar should be peanuts. You can also make your own peanut butter at home if you have a food processor or high powered blender.

For a peanut-free version of these banana blondies, you can substitute almond butter or cashew butter instead of peanut butter. Or to make these entirely nut-free you can use pumpkin seed butter or sunflower seed butter instead of peanut butter.

How to make them

Start by preheating the oven, then mash the bananas in a large mixing bowl. I like to use a potato masher to do this but you can use a fork if you don’t have a potato masher.

Once the bananas are mashed, add the maple syrup, peanut butter, vanilla extract, salt, and cinnamon. Mix well (I find it’s best to use a whisk).

Next you’ll add the coconut flour and mix once more before transferring the batter to a parchment paper lined 8 inch square baking dish. Be sure to spread the batter into an even layer before sprinkling the chopped dark chocolate on top (or you can substitute vegan chocolate chips if you prefer).

The last step is to bake them at 350 degrees Fahrenheit for 55minutes (or until they’re golden brown around the edges), then let cool before enjoying. Makes approximately twelve vegan peanut butter banana blondies.

Optional addition

For some extra crunch, sprinkle 1/4 cup chopped peanuts on top of the batter before baking.
