Grilled Peanut Butter Banana Sandwich

Some mornings and afternoons just call for a little nostalgia and comfort and nothing hits the spot like a Grilled Peanut Butter Banana Sandwich. This recipe gives the classic peanut butter and banana pairing a crispy twist that turns ordinary bread into a golden and gooey treat with minimal ingredients. It is the snack I make when I want to feel like a kid again but with a bit of grownup-savvy flavor.

The first time I made this with mayonnaise instead of butter I could not believe how perfectly golden and crisp the bread turned out. Now it is my go to trick whenever I make any sweet or savory grilled sandwich.

Ingredients

• Thick white bread: gives a sturdy base and crisps up nicely on the griddle. Look for fresh bakery-style bread for the best texture.
• Mayonnaise: helps the bread brown and adds a subtle richness that elevates the whole sandwich. Use a high quality real mayonnaise for the crispiest crust.
• Smooth peanut butter: spreads evenly and melts perfectly. Choose one with a hint of salt for the best balance.
• Banana: brings sweetness and moisture. Pick a just ripe banana that yields gently to pressure but is not mushy for ideal sliceability.

Instructions

Smooth the Slices:

Gently spread a thin layer of mayonnaise on one side of each slice of bread making sure to coat edge to edge for even crisping

Spread the Peanut Butter:

Flip the bread so the dry side faces up and evenly spread peanut butter across two slices reserving the mayo-coated sides for grilling

Add the Banana:

Layer thin rounds of banana right over the peanut butter pressing lightly so they stick and do not slide out when cooking

Assemble the Sandwich:

Lay two slices of bread mayonnaise side down and peanut butter side up onto a preheated griddle or skillet Arrange the remaining slices on top peanut butter side down so the mayonnaise is on the outside

Grill to Perfection:

Cook over medium-high heat for about two minutes until the underside is golden and crisp Gently flip and cook the other side for another two minutes The sandwich is ready once both sides are deeply golden the peanut butter is warm and a little oozing

Save it

I have a real soft spot for peanut butter sandwiches of any kind but this combo is special. My youngest requested peanut butter and banana for weeks on end when she was a toddler and now it has become our family’s favorite rainy day snack tradition.

Storage Tips

This sandwich is definitely best hot and fresh with the bread at its crispiest but if you want to make ahead or save leftovers wrap tightly in foil and keep in the fridge up to twenty four hours. Reheat in a toaster oven or skillet so the bread re-crisps. Avoid microwaving since it can make everything soggy.

Ingredient Substitutions

Switch out the white bread for whole wheat or sourdough for a different flavor profile. Crunchy peanut butter works just as well for extra texture. You can use almond or sunflower seed butter for a nut free version and swap the banana for sliced strawberries or even a dollop of jam for a new twist.

Serving Suggestions

I love to cut this sandwich into triangles and sprinkle with a pinch of cinnamon or a dusting of powdered sugar for a dessert feel. Pair it with a glass of cold milk or a cup of coffee for grownups. If you want extra indulgence serve with a scoop of vanilla ice cream on the side.

Cultural Note

The grilled peanut butter and banana sandwich was famously beloved by Elvis Presley who added bacon to his version. While this recipe is lighter it keeps the spirit of classic diner comfort food alive with its gooey center and crispy crust.

Save it

This sandwich is simple but packed with comfort and fun. Try it the next time you want both nostalgia and a little grown up twist.
