This grilled peanut butter banana sandwich is my go to snack for when I need something warm gooey and a little nostalgic It takes the traditional PB and banana combo and turns it into an oozy toasty treat that always satisfies my craving for comfort food
I first started making these sandwiches when my kids refused to eat their bananas plain Now we all look forward to sandwich night and never have leftovers
Ingredients
- Thick white bread: Makes a sturdier sandwich that grills up beautifully Look for bakery loaves or Texas toast if available
- Mayonnaise: Adds a golden crispy crust instead of butter Use fresh mayo for the best flavor
- Smooth peanut butter: Melts into every bite Choose natural peanut butter for a deeper roasted flavor
- Ripe banana: Brings sweetness and creaminess Pick bananas with plenty of brown spots for the richest flavor
Step-by-Step Instructions
- Prep the Bread:
- Spread a thin layer of mayonnaise on one side of each bread slice making sure to reach the edges for even browning
- Add the Peanut Butter:
- Flip the bread and spread a generous layer of peanut butter on the plain side of each slice focus on getting it close to the edges for even flavor
- Layer the Banana:
- Arrange banana slices in a single layer over the peanut butter on two of the bread slices press them down gently so they stick
- Assemble the Sandwiches:
- Top each banana covered slice with a plain slice mayo side out peanut butter sides touching the bananas
- Grill to Perfection:
- Heat a nonstick skillet or griddle over medium high Lay the sandwiches mayo side down Grill for about two minutes or until golden brown and crisp Use a spatula to check the color
- Flip and Finish:
- Carefully flip the sandwiches Continue grilling for another two minutes per side until both sides are crisp and the peanut butter inside is starting to ooze

One of my favorite memories is making these on lazy Sunday mornings when everyone in my family would come running once the scent hit the kitchen My favorite part is watching the peanut butter get perfectly melty and thick between the warm slices
Storage Tips
If you have leftovers let them cool completely then wrap in foil and refrigerate Reheat in a skillet over low heat to restore crispiness They are best enjoyed fresh but can last up to a day in the fridge

Common Recipe Questions
- → Why spread mayo instead of butter before grilling?
Mayonnaise creates a crisp, golden crust on the bread while letting the inside flavors shine through without adding heaviness.
- → Can I use a different type of bread?
Absolutely—sourdough, multigrain, or thick whole wheat bread work well and add their own unique textures.
- → Are there creative ways to add flavor?
Try a sprinkle of cinnamon, drizzle of honey, or chocolate chips between the bread before grilling for fun variations.
- → How do I keep the sandwich from getting soggy?
Use fully ripe but not mushy bananas, gently press them into the peanut butter, and grill over medium-high heat to lock in that crispness.
- → Can I prepare these sandwiches in advance?
For the best texture, grill just before serving, but you can prep ingredients ahead for speedy assembly when needed.
