Ripe Banana: Choose bananas with yellow peels and a few brown spots for optimal flavor and texture.
Butter: It helps to achieve a crispy, golden-brown exterior when grilled.
Drizzle of Honey or Sprinkle of Cinnamon Sugar (Optional): Honey provides additional sweetness, while cinnamon sugar creates a crunchy, caramelized crust.

How to Make a Grilled Peanut Butter and Banana Sandwich

Follow these easy steps to make it:

Spread the peanut butter. Spread a generous amount of peanut butter on one side of each slice of bread. Cover it from edge to edge.
Add the banana slices. Arrange the banana slices evenly over the peanut butter on one of the bread slices. Optionally, drizzle a little honey over the bananas for extra sweetness.
Close the sandwich. Top with the remaining slice of bread, peanut butter side down, to form a sandwich.
Butter the bread. Spread the softened butter on the outside of both slices of bread.
Grill the sandwich. Heat a skillet or griddle over medium heat. Place the sandwich on the hot surface and cook for 2-3 minutes per side. Cook until the bread is toasted to a golden brown color and the peanut butter is melty.
Cool and garnish. Remove from heat and let cool for a minute before slicing in half diagonally.
Serve and enjoy. Serve warm and enjoy the gooey, crispy, sweet, and nutty combination!

Tips for the Best Grilled Peanut Butter and Banana Sandwich

These tried-and-true tips make this sandwich even better:

The thicker, the better. Apply a thick layer of peanut butter on both slices of bread to ensure a creamy, flavorful sandwich.
Be even with the bananas. Cut the banana into even, 1/4-inch slices for optimal distribution and easier grilling.
Have fun with add-ins. Try sprinkling granola, mini chocolate chips, or shredded coconut for added crunch and flavor.
Try tasty variations. Swap peanut butter for almond or cashew butter. Drizzle with honey, or sprinkle with cinnamon sugar for tasty twists on the classic.
Work some panini perfection: Grilling it in a panini press gives it those classic grill lines.
