Why use mayonnaise instead of butter?

Mayonnaise is the recipe's exterior cooking fat. Its thin layer spreads easily and helps all four outside bread faces brown evenly.

Which side gets the peanut butter?

Spread peanut butter on the non-mayonnaise side of all four slices so it faces inward around the banana.

How ripe should the banana be?

Use one banana that is ripe and sweet but still firm enough to cut into tidy thin rounds.

How many sandwiches does the recipe make?

Four bread slices make exactly two sandwiches, listed as two servings, in 10 minutes total.

Grilled Peanut Butter Banana Ingredients

Four thick white bread slices, mayonnaise, creamy peanut butter, and one ripe banana | Recipes by Clare

Gather exactly 4 slices thick white bread, 2 tablespoons mayonnaise, 4 tablespoons creamy peanut butter, and 1 ripe banana sliced thin. Those four ingredients make two complete sandwiches; nothing else is required.

Choose a banana that is ripe enough to be sweet but still firm enough to slice cleanly. Thick bread supports the warm filling, while creamy peanut butter spreads evenly and softens as the sandwiches heat.
