Main ingredients and substitutions
Bananas give these vegan peanut butter blondies a moist texture and add sweetness. 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 and I don’t recommend substituting other flours. 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 agave if you prefer.
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 the blondies at 350 degrees Fahrenheit for 55minutes (or until they’re golden brown around the edges), then let cool before enjoying.
Optional addition
For some extra crunch, sprinkle 1/4 cup chopped peanuts on top of the batter before baking.
Storage
Store these vegan peanut butter blondies in an airtight container for up to five days or freeze them for up to six months.
