Spread a thin, even layer of mayonnaise over one side of each bread slice, reaching all edges to ensure an even golden crust.
02 -
Flip each bread slice and spread a generous layer of peanut butter on the uncoated side, carrying the spread as close to the edges as possible.
03 -
Place banana slices in a single layer across the peanut butter on two of the slices. Press lightly so the banana adheres to the peanut butter.
04 -
Place the remaining two slices of bread on top of the banana-covered slices, mayonnaise side facing outward, to create sandwiches with peanut butter and banana inside.

Heat a nonstick skillet or griddle over medium-high. Place sandwiches mayo side down. Cook for about 2 minutes, or until golden and crisp. Use a spatula to check the undersides.
06 -
Carefully flip the sandwiches and continue grilling for another 2 minutes or until both sides are crisp and the filling is warm and creamy.

Remove from the skillet, let stand briefly, and slice in half for easier serving. Enjoy hot for best texture.
