Step-by-Step Instructions
Step 1: Preheat and Prep

Step 2: Blend the Base
In a blender, combine oats, banana, egg, milk, peanut butter, cocoa powder, maple syrup, baking powder, vanilla, and salt.

Step 3: Add Chocolate
Pour the mixture into your baking dish. Stir in chocolate chips, saving a few to sprinkle on top.
Step 4: Bake
Bake for 20–25 minutes until the top is set and a toothpick comes out mostly clean (a few moist crumbs are perfect).
Step 5: Serve
Let cool for 5 minutes. Top with a drizzle of peanut butter, extra chocolate chips, or mini peanut butter cups. Enjoy warm!
