Ingredients
- Thick white bread: Brings sturdy structure and crisps up beautifully Choose bakery fresh slices for best texture
- Mayonnaise: Adds a perfectly browned crust and extra flavor Choose real egg mayo for richness
- Smooth peanut butter: Provides creamy salty sweetness Go with your favorite brand just ensure it is easy to spread
- Banana: Offers mellow sweetness and creamy bite Use fully ripe bananas for maximum flavor
Step-by-Step Instructions
- Spread the Mayo:
- Smooth a thin even layer of mayonnaise on one side of each bread slice Use the back of a spoon for full coverage This step ensures golden color and flavor
- Add the Peanut Butter:
- Spread peanut butter on the inner sides of each bread slice Make sure to reach the edges for a satisfying bite every time
- Layer the Bananas:
- Cut your banana into thin uniform slices Arrange them gently over two of the peanut butter coated slices Cover the peanut butter fully but avoid overfilling
- Assemble the Sandwiches:
- Place the two banana topped slices mayo side out onto the griddle or pan Top each with the remaining slices keeping mayo side out and peanut butter on the inside
- Grill to Golden Perfection:
- Cook over medium high heat for about two minutes Check the underside for a rich golden brown color Carefully flip with a spatula and cook the second side for another two minutes or until both sides are evenly toasted and the peanut butter is just starting to melt

The peanut butter is my favorite part because it gets extra melty and coats the bananas in every bite I grew up watching cartoons with this sandwich and now my kids beg for it after weekend soccer games
