Ingredients You’ll Need
These ingredients are wonderfully simple but each one plays a vital role in creating the perfect grilled peanut butter banana sandwich. From the creamy peanut butter that adds richness to the sweet banana slices that give every bite a fresh burst of flavor, each component is thoughtfully chosen to harmonize beautifully.
- 1 medium banana, cut into thin rounds: Choose a ripe but firm banana for the ideal balance of sweetness and texture.
- 4 tablespoons creamy peanut butter: Use your favorite smooth peanut butter for a rich, silky spread that melts beautifully.

- 4 slices thick white sandwich bread: Thick slices hold up to grilling and provide the perfect crispy crunch you crave.
How to Make Grilled Peanut Butter Banana Sandwich Recipe
Step 1: Prepare the Bread
Start by laying out your bread slices. You’re about to create a crispy exterior, so it’s important to work with fresh, thick-cut white bread that crisps up beautifully without getting soggy. This will be the wonderful base of your sandwich.
Step 2: Spread the Mayonnaise
Spread a thin, even layer of mayonnaise on just one side of each slice of bread. This clever ingredient ensures your sandwich grills up golden and crispy, adding a subtle tanginess that perfectly balances the peanut butter and banana sweetness.
Step 3: Apply the Peanut Butter
On the sides of the bread without mayo, slather the creamy peanut butter generously. Be sure to cover the entire surface from edge to edge to get pockets of gooey peanut butter in every single bite.
Step 4: Add Banana Slices
Lay out the banana rounds evenly on two slices of the peanut butter-coated bread. The bananas add a natural sweetness and softness that pairs beautifully with the crunchy bread and creamy peanut butter layers.
Step 5: Assemble the Sandwich
Take the remaining peanut butter bread slices and flip them peanut butter side down onto the banana-topped slices, creating two perfect sandwiches. The peanut butter on both sides helps keep the bananas nestled safely in the middle.
Step 6: Grill the Sandwiches
Heat a pan or griddle over medium heat. Place the sandwiches down mayo-side first so that crispy magic begins right away. Let each side grill until it’s a beautiful golden brown, about two minutes, then carefully flip and repeat. Once both sides are crispy and the filling is warmed through, your sandwiches are ready to delight!
How to Serve Grilled Peanut Butter Banana Sandwich Recipe
Garnishes
For a fun twist, sprinkle a little cinnamon or a drizzle of honey on top just before serving. Chopped nuts like walnuts or pecans add a crunchy contrast that elevates the texture, making every bite even more satisfying.
Side Dishes
Serve alongside a fresh fruit salad for a refreshing burst or some crunchy veggie sticks to balance the richness. A cold glass of milk or your favorite coffee completes this snack with classic comfort vibes.
Creative Ways to Present
Cut your sandwich into small triangles for bite-sized party snacks, or try stacking multiple layers with added sliced strawberries or a smear of Nutella for an indulgent twist. Wrapping them in parchment paper and adding a fun toothpick makes for a charming picnic treat.
Make Ahead and Storage
Storing Leftovers
If you have any leftover grilled peanut butter banana sandwiches, wrap them tightly in plastic wrap and store in the fridge for up to 2 days. This keeps the bread from drying out and preserves the flavors nicely.
Freezing
To freeze, wrap each sandwich in foil or airtight wrap and place in a freezer-safe bag. Frozen sandwiches keep well for up to one month, making them a great option for quick snacks whenever you need a comforting bite.
Reheating
Warm leftovers in a toaster oven or on a skillet over low heat to regain that crispy crunch. Avoid microwaving if possible, as it can result in a soggy exterior. A few minutes turning gently on each side will bring your sandwich back to life perfectly.
FAQs
Can I use crunchy peanut butter instead of creamy?
Absolutely! Crunchy peanut butter will add delightful texture with little nutty bits in every bite, though creamy peanut butter tends to meld more smoothly with the banana.
Why is mayonnaise used in this recipe?
Mayonnaise helps create a beautifully golden and crisp crust when cooking the sandwich. It might seem unusual, but it’s a secret trick to enhance the texture without adding a mayonnaise taste.
What kind of bread works best for this sandwich?
Thick white sandwich bread is ideal because it crisps up nicely while holding the fillings without falling apart. You can experiment with other breads, but avoid super thin or very dense loaves.
Can I add other toppings or spreads?
Definitely! Sliced strawberries, a drizzle of honey, or even a sprinkle of cinnamon all work wonderfully to complement the peanut butter and banana flavors.
Is this sandwich suitable for kids?
Yes, it’s a kid-friendly recipe packed with familiar, comforting flavors. Just be sure to slice the sandwich into manageable pieces, especially for younger children.
