Preheat your waffle iron and let it get nice and toasty.
Now, toss all your ingredients into the blender—oat flour, banana, eggs, peanut butter, cinnamon, vanilla extract, and baking powder—and give it a good mix until it’s well blended.
Grab your avocado oil and lightly coat the waffle iron to prevent sticking.
Spread the batter evenly, close the lid, and cook for about 3 minutes.
Once they’re done, carefully lift the waffles out of the iron and onto your plate. Serve them warm and enjoy!
