There’s something undeniably comforting about the first bite of a warm, gooey peanut butter and banana sandwich straight off the griddle. I still remember the Saturday mornings in my childhood kitchen: the air thick with butter melting on the skillet, the sweet scent of caramelizing banana wafting up as I flipped my sandwich—always a little too eager to dig in. This Grilled Peanut Butter Banana Sandwich takes that nostalgic memory and elevates it with just the right balance of creamy peanut butter, ripe banana, and crispy, golden bread.
In under 10 minutes, you’ll have a treat that’s perfect for busy mornings, an indulgent afternoon snack, or even a simple dessert when you’re craving something warm and satisfying. Plus, it’s incredibly adaptable: a dash of cinnamon, a drizzle of honey, or even a sprinkle of mini chocolate chips can take this sandwich from great to downright irresistible.
Before we dive into the fun, let’s make sure you have everything you need.
Ingredients (Serves 1)
2 slices of your favorite bread (I love a hearty whole-wheat or a soft brioche)
2 tablespoons creamy peanut butter
1 medium ripe banana, peeled and sliced (lengthwise or into rounds)
1 tablespoon butter or margarine, softened
Prep time: 5 minutes • Cooking time: 5 minutes • Total time: 10 minutes
Why You’ll Love This Sandwich
Sweet meets savory: The natural sugars in the banana caramelize against the buttered bread, while the peanut butter provides that savory, nutty counterpoint.
Quick & fuss-free: No fancy equipment required—just a skillet or griddle, a spatula, and a willing appetite.
Customizable: Swap in almond butter, add honey, or sprinkle on chocolate chips; the possibilities are endless.
Steps
Prep your bread and peanut butter
Lay your two slices of bread on a clean cutting board. Using a butter knife or spreader, evenly coat one side of each slice with a generous layer of creamy peanut butter. Don’t be shy—this is what gives you that irresistibly gooey center!Layer on the banana
Arrange your banana slices on top of the peanut butter on one slice of bread. If you’re in the mood for presentation, slice lengthwise so you get those long, elegant ribbons of banana peeking out when you cut the sandwich. Leave a small border (about ¼ inch) around the edge—this helps seal everything inside once you close it up.Assemble the sandwich
Place the second slice of bread, peanut butter side down, onto the banana-topped slice. Gently press around the edges to make sure everything sticks together. At this point, your sandwich should feel like a little pillow of deliciousness, ready for a warm, buttery transformation.Get your skillet ready
Heat a nonstick or cast-iron skillet over medium heat. Add the softened butter, swirling it around so it coats the entire cooking surface. You want the butter to foam but not burn—too hot, and you’ll end up with charred bread rather than that perfect golden crisp.
Grilling to Golden Perfection & Handy Tips
When I first tried grilling this sandwich, I was convinced the key was high heat and lightning-fast flipping. Spoiler: that approach leads to a charred exterior and a cold, under-melted center. What really makes this Grilled Peanut Butter Banana Sandwich sing is moderate heat, a little patience, and a gentle flip—allowing the bread to caramelize just enough while giving the peanut butter and banana time to become delightfully gooey.
Steps
Place the sandwich in the pan
Gently lay your assembled sandwich into the melted butter on the skillet. You should hear a soft sizzle—not a furious crackle. If it’s crackling, turn the heat down a notch. The goal is a slow, steady browning that lets the sugars in the banana and peanut butter meld together.First-side grill (2–3 minutes)
Let the sandwich cook, undisturbed, for about two to three minutes. Peek underneath with your spatula: you’re looking for a deep golden-brown hue, the kind that hints at caramelized edges. If your bread is browning too quickly, lower the heat; too slowly, turn it up just slightly.Flip with confidence
Slide your spatula all the way under one side, coax the sandwich up, and flip it over in one smooth motion. Resist the urge to press down hard—just a gentle nudge will ensure good contact with the skillet.Second-side grill (2–3 minutes)
Cook the second side until it matches the first in color and crispness. At this point, the peanut butter should be softened through, and the banana warmed enough that it’s pillow-soft and slightly melting into the bread.Rest and slice
Transfer the sandwich to a cutting board and let it rest for about 30 seconds. This brief pause prevents scorching your tongue on molten filling and lets everything settle. Then, slice in half diagonally for a classic look—or down the middle if you prefer neat rectangles.Serve immediately
The sandwich is at its peak right off the griddle: warm, gooey, and fragrant. Enjoy it plain, or dress it up with one of the variations below.
Pro Tips & Variations
Drizzle of sweetness
Before closing the sandwich, drizzle a teaspoon of honey or pure maple syrup over the banana slices for an extra layer of sweetness. It caramelizes beautifully alongside the peanut butter.Cinnamon kick
Mix a pinch of ground cinnamon into your peanut butter before spreading. You’ll get warm, spiced notes in every bite.Chocolate bliss
Sprinkle a handful of mini chocolate chips over the bananas for a gooey, melty surprise that pairs beautifully with peanut butter.Crunch factor
Swap in chunky peanut butter or sprinkle a handful of chopped peanuts over your banana slices for a contrast in texture.Bread choice matters
Brioche or challah will give you a rich, buttery flavor; whole-wheat bread adds a nutty complexity; sourdough lends a tangy twist. Toasting the bread lightly before assembling can help it hold up better if you’re adding extra fillings.Dairy-free option
Use a plant-based margarine or coconut oil for grilling, and be sure your peanut butter has no added milk solids. The result is just as indulgent without the dairy.Make-ahead hack
Assemble the sandwich, wrap it tightly in plastic, and refrigerate for up to two hours. When you’re ready, grill directly from the fridge—just add an extra 30 seconds per side to ensure it heats through.
Frequently Asked Questions
1. Can I swap in a different nut butter?
Absolutely! Almond butter, cashew butter, or sunflower seed butter all work beautifully. Just choose a creamy variety for the best melt and spreadability, and adjust any drizzles of honey or syrup to taste, since different nut butters vary in sweetness.
2. What’s the best way to tell if my banana is ripe enough?
Look for bananas with bright yellow skins and a few small brown freckles. Overly green bananas won’t caramelize properly, while overly spotted ones can turn mushy. Aim for that “just right” stage where the flesh is sweet but still holds its shape when sliced.
3. How can I make this sandwich completely vegan?
Swap the butter for a plant-based margarine or coconut oil, and double-check that your peanut butter (or other nut butter) is free of milk solids. Follow the recipe steps exactly the same—your sandwich will be every bit as gooey and delicious.
4. My bread sometimes gets soggy—how do I avoid that?
There are two easy fixes: first, lightly toast your bread before assembling so it holds up better; second, spread a very thin layer of butter on the outside of each slice before grilling (in addition to the melted butter in the pan) to create an extra barrier against moisture.
5. Can I assemble these ahead of time?
Yes! Wrap the ungriddled sandwich tightly in plastic or parchment and refrigerate for up to two hours. When you’re ready, grill it straight from the fridge—just add about 30 seconds per side to ensure the filling heats through.
6. What’s the best way to store leftovers?
Because the joy of this sandwich is in its warm, melty center, it’s best eaten fresh. However, you can keep an ungrilled assembled sandwich in an airtight container at room temperature for up to four hours. Re-grill briefly to refresh the crisp before serving.
7. Any tasty side or drink pairings?
A chilled glass of milk or a frothy café latte complements the sweet-savory flavors perfectly. For a lighter option, try herbal tea with a hint of cinnamon or a fruit-forward smoothie—both cut through the richness in a lovely way.

Grilled Peanut Butter Banana Sandwich
Description
A quick and satisfying sweet-savory treat featuring creamy peanut butter and ripe banana slices melted together between golden, buttery bread. The warm, caramelized edges and soft, gooey center make this sandwich an ideal breakfast option or an indulgent afternoon snack.
Ingredients
2 slices of your favorite bread
2 tablespoons creamy peanut butter
1 medium ripe banana, peeled and sliced lengthwise or into rounds
1 tablespoon butter or margarine, softened
Prep time: 5 minutes
Cooking time: 5 minutes
Total time: 10 minutes
Servings: 1 sandwich
Calories per serving: approximately 350 kcal
Instructions
Spread peanut butter evenly over one side of each slice of bread. Arrange banana slices on top of the peanut butter on one slice, covering the surface but leaving a small border for sealing. Top with the second slice of bread, peanut butter side down, pressing gently to adhere.
Heat a skillet or griddle over medium heat. Add butter and let it melt, coating the cooking surface. Carefully place the assembled sandwich into the pan.
Cook until the bottom slice is golden brown and crisp, about two to three minutes. Flip the sandwich and cook the second side until it is equally browned and the peanut butter and banana are warmed through.
Transfer the sandwich to a cutting board. Let it rest for 30 seconds, then slice in half diagonally or down the middle, as preferred. Serve immediately while still warm and gooey.
Notes
For extra sweetness drizzle a little honey or maple syrup over the banana slices before closing the sandwich. A sprinkle of cinnamon or a handful of mini chocolate chips inside adds another layer of flavor. To make this sandwich dairy-free, use a plant-based margarine for grilling and ensure the peanut butter contains no added milk solids. Leftover slices can be kept in an airtight container for up to four hours, but grilling fresh yields the best texture. If you prefer a crunchier bite, substitute chunky peanut butter or lightly toast the bread before assembling.
