Ingredients You’ll Need
This recipe calls for just a handful of ingredients, each essential in creating the perfect balance of flavors and texture. They’re everyday pantry staples that come together to produce something extraordinarily comforting and tasty.
- Banana (medium, sliced): Adds natural sweetness and a creamy texture that softens beautifully when grilled.
- Creamy peanut butter (4 tablespoons): Offers a nutty, rich base with a smooth texture that complements the banana.
- Mayonnaise (2 tablespoons): An unexpected ingredient that crisps up the bread to golden perfection without overpowering the flavors.
- Thick white sandwich bread (4 slices): Sturdy enough to hold the filling and create that irresistible crunchy outside when grilled.
How to Make Grilled Peanut Butter Banana
Step 1: Prepare the Bread
Start by spreading a thin, even layer of mayonnaise on one side of each slice of bread. This small step is the secret to getting the bread beautifully crisp and golden when grilled, without making it greasy or heavy.
Step 2: Apply Peanut Butter
Next, take the slices without mayo on them and slather each piece generously with creamy peanut butter, spreading it edge to edge. This not only ensures every bite bursts with flavor but also acts as a cozy, creamy barrier between the bread and banana.
Step 3: Add Banana Slices
Lay the thin banana rounds on top of the peanut butter on two slices of bread, covering them fully. This creates a luscious, fruity layer that melds beautifully during grilling. Feel free to taste a few banana slices here—they’re the star of the show!
Step 4: Assemble Sandwiches
Now, flip the remaining peanut butter–covered bread (without mayo) on top of the banana-topped slices, peanut butter side down, so the peanut butter touches the bananas. This way, all that creaminess is perfectly sealed inside.
Step 5: Grill Sandwiches
Preheat your pan or griddle over medium heat until hot. Place the sandwiches mayo-side down on the pan, allowing them to sizzle as the bread crisps up. Grill for a couple of minutes until the bottom is golden brown, then carefully flip and toast the other side until equally golden and the filling is nicely warmed through. The peanut butter will soften, and the bananas slightly caramelize, creating a mouthwatering combination.
How to Serve Grilled Peanut Butter Banana

Garnishes
To elevate your Grilled Peanut Butter Banana, consider sprinkling a pinch of cinnamon or drizzling a little honey on top. A dash of flaky sea salt can also balance the sweetness beautifully. Fresh mint leaves bring a refreshing contrast, adding a pop of color and a bright flavor.
Side Dishes
This sandwich pairs wonderfully with a simple green salad dressed lightly with lemon vinaigrette to cut through the richness. For a more indulgent meal, serve it alongside vanilla ice cream or a scoop of Greek yogurt with fresh berries for a delightful contrast between warm and cool.
Creative Ways to Present
Try cutting your Grilled Peanut Butter Banana into fun shapes using cookie cutters to make it more appealing to kids or serve it open-faced with extra banana slices and a sprinkle of chopped nuts for added crunch. You can also make mini versions on small bread slices for party appetizers that are sure to be a hit!
Make Ahead and Storage
Storing Leftovers
If you have leftovers, wrap them tightly in plastic wrap or place in an airtight container and store in the refrigerator for up to two days. The sandwich may lose some crispiness but will still taste delicious when reheated.
Freezing
While it’s best enjoyed fresh, you can freeze your Grilled Peanut Butter Banana sandwiches. Wrap each sandwich individually and place them in a freezer-safe bag. They’ll keep well for up to one month and can be thawed overnight in the fridge before reheating.
Reheating
To bring back that crispy exterior, reheat your sandwich in a skillet over medium heat rather than the microwave. Heat each side for a couple of minutes until warmed through and crispy again. Avoid overheating to keep the bananas from turning too mushy.
FAQs
Can I use crunchy peanut butter instead of creamy?
Absolutely! Crunchy peanut butter will add a nice texture contrast which some people love. Just keep in mind the sandwich might be a bit more textured overall, but equally delicious.
Why is mayonnaise used in this recipe?
Mayonnaise spreads smoothly and contains oil that helps the bread crisp up beautifully without burning or becoming greasy. It’s a clever alternative to butter and gives a perfect golden crust.
Can I substitute the bread with something else?
Yes! Thick slices of brioche, challah, or even gluten-free bread work wonderfully. Just make sure the bread isn’t too thin so it can handle grilling without falling apart.
Is this recipe suitable for kids?
Definitely! The flavors are simple and approachable, and the peanut butter and banana combo is a classic kid favorite. Just be mindful of any peanut allergies.
Can I add other ingredients to the sandwich?
Feel free to get creative! Adding a sprinkle of cinnamon, a drizzle of honey, or even a few chocolate chips inside before grilling can take your Grilled Peanut Butter Banana to the next level.
