This easy grilled peanut butter banana sandwich delivers a perfect mix of crispiness and gooey sweetness, making it my go-to when I want a comforting breakfast or snack that comes together in minutes. Thick slices of bread, creamy peanut butter, and perfectly ripe bananas meet the magic of the griddle. A swipe of mayo on the outside gives the crust a perfectly golden crunch that beats ordinary butter. Whether it is a school morning or just a busy weekday, this sandwich hits the spot every time with minimal prep.

I first made this when I had overripe bananas and no time. My kids now ask for it almost every Saturday morning.

Ingredients

  • Thick white bread: adds structure and turns golden when grilled
  • Mayonnaise: gives a golden crust with rich flavor instead of butter

Ingredients

→ Bread

01 4 slices thick white bread

→ Spreads

02 2 tablespoons smooth peanut butter
03 2 tablespoons mayonnaise

→ Fruit

04 1 ripe banana, thinly sliced

Steps

Step 01

Spread a thin layer of mayonnaise on one side of each bread slice to ensure a golden, crispy crust when grilled.

Step 02

Flip the bread slices and spread peanut butter evenly on the side that will face inward in the sandwich.

Step 03

Distribute thin slices of ripe banana evenly over the peanut butter on two of the bread slices.

Step 04

Place two bread slices mayo side down on a preheated griddle or non-stick frying pan, then top with the remaining two slices peanut butter side down, so mayo faces outward.

Step 05

Cook over medium heat for 2 to 3 minutes until the bread bottoms are golden and crispy, then flip carefully and grill the other side similarly until both sides are golden and filling is warm.

Notes

  1. Use mayonnaise instead of butter for an evenly golden crust. Press gently with a spatula during grilling for improved contact. Let the sandwich rest for one minute before slicing to allow the filling to set.
  2. Leftover sandwiches can be stored wrapped in foil in the refrigerator for up to one day and reheated in a pan to restore crispiness.
