Step‑by‑Step Instructions for Grilled Peanut Butter Banana Sandwich
Step 1: Prepare the Bread
Start by laying out four slices of thick white bread on a clean surface. On one side of each slice, spread a thin, even layer of mayonnaise, making sure to cover the surface completely for that crispy texture. This is the secret to achieving a delightful golden-brown crust when you grill the sandwiches.
Step 2: Spread the Peanut Butter
Flip two of the slices over, revealing the non-mayo side, and generously spread creamy peanut butter evenly from edge to edge. Make sure the peanut butter layer is thick enough to mix well with the bananas, providing a rich flavor in your Grilled Peanut Butter Banana Sandwich.
Step 3: Add the Bananas
Slice a ripe banana into thin rounds and layer them over the peanut butter, arranging them nicely to cover the surface completely. The bananas should be placed snugly, ensuring that every bite is packed with sweetness. This filling will bring both flavor and moisture to the sandwich as it cooks.
Step 4: Assemble the Sandwich
Carefully place the second slice of bread, mayonnaise side facing out, atop the banana-topped slice. Press down gently to help the sandwich adhere and to lock in the delicious fillings. The peanut butter and banana should be nestled securely between the two slices, ready for grilling.
Step 5: Heat the Skillet
Place a skillet over medium heat and allow it to warm up for a few minutes. The goal is to achieve the right temperature to get that perfect crispy exterior without burning the bread. You’ll know the skillet is ready when a drop of water sizzles upon contact.
Step 6: Grill the Sandwiches
Carefully place your assembled Grilled Peanut Butter Banana Sandwiches in the hot skillet, mayo side down. Cook for about 3-4 minutes, or until the bread turns golden brown and crispy. Keep an eye on them, and gently press down with a spatula to encourage an even grill.
Step 7: Flip and Finish Grilling
Once the first side is beautifully crisped, carefully flip the sandwiches using a spatula. Grill the other side for another 3-4 minutes, ensuring it also reaches a lovely golden color. Both sides should be crisp, while the inside should be warm and melty, bursting with peanut butter and bananas.
Step 8: Serve and Savor
Once grilled to perfection, remove the sandwiches from the skillet and let them cool for a moment on a cutting board. Slice them in half to reveal the gooey filling, then serve warm for the best experience. Pair them with a hot beverage for a delightful snack or breakfast!
