Grilled Peanut Butter Banana Sandwich with Golden Crust

There is something so nostalgic and comforting about a warm grilled peanut butter banana sandwich. This recipe has saved breakfast more than once in my home and it always hits the spot as a sweet snack or even a quick dessert. The combo of creamy peanut butter and perfectly ripe bananas tucked between golden crisp bread with a surprise mayonnaise twist truly elevates a simple childhood classic.

My favorite part of this sandwich is the crunch you get from grilling the mayo side. The first time I tried it was with my grandmother who swore by mayo instead of butter for every grilled bread situation. It is now my absolute go to whenever I want a golden crust.

Ingredients

Thick white bread: for structure and a plush bite look for fresh or bakery loaves with a soft crumb
Mayonnaise: to crisp and brown the bread even better than butter and to add a subtle savory richness choose a good quality full fat version for best results
Smooth peanut butter: for irresistibly creamy texture make sure to stir well if using natural peanut butter to avoid oil separation
Banana: sliced thin for maximum caramelization and flavor use ripe bananas with some spots for the sweetest result

Instructions

Prep the Bread:: Smooth a thin even layer of mayonnaise on one side of each slice of bread. This step ensures a crispy flavorful crust. Use the back of a spoon or an offset spatula for even coverage.
Peanut Butter Layer:: Spread peanut butter on the plain side of all four slices of bread. Be generous so every bite is creamy and nutty. Try to reach the edges for full coverage.
Add the Banana:: Arrange banana slices in a single layer on top of the peanut butter on two slices of bread. Slightly overlapping is okay as they will soften and meld together when grilled.
Assemble the Sandwich:: Take the prepared slices with banana and layer them with the two remaining slices peanut butter side down and mayonnaise side up so the outside will crisp up on the griddle.
Grill the Sandwich:: Place sandwiches on a preheated griddle set to medium-high heat with the mayonnaise side touching the surface. Cook for about two minutes until deep golden and crisp. Flip carefully with a spatula and cook the second side for an additional two minutes. Both sides should be golden and the peanut butter warm and melty.
Enjoy Warm:: Let sandwiches rest for a brief minute before slicing—this lets the filling set just enough and prevents burns. Enjoy straight off the griddle for best texture and flavor.

Storage Tips

If you have leftovers allow sandwiches to cool completely. Wrap tightly in foil and store in the refrigerator for up to a day. Reheat in a toaster oven or skillet to bring back the crisp texture.

Ingredient Substitutions

Try whole wheat or sourdough bread for a nutty flavor. Replace peanut butter with almond or cashew butter. Use honey instead of banana for a sweet twist but do not skip the creamy spread for texture.

Serving Suggestions

Serve with hot chocolate or coffee for a comforting breakfast. Add a sprinkle of cinnamon on the banana before grilling for warmth. Cut into strips for a kid friendly snack or pack for school lunches.

Cultural Context

Grilled peanut butter sandwiches have roots in American comfort food but got popular thanks to Elvis Presley who adored the peanut butter and banana combo. The mayonnaise on the outside is a Southern chef secret for extra crunch.

Seasonal Adaptations

Add sliced strawberries in spring for a fresher take Try apple slices and a touch of cinnamon in autumn Use thick cut whole grain bread in winter for extra fiber
