Spread 2 tbsp peanut butter on two slices of bread. Spread 2 tbsp jam on the other two slices. Sandwich together.
Add pretzels to a shallow plate or bowl and crush with the bottom of a cup or rolling pin until coarse (like panko breadcrumbs).
Spread softened butter on the outside of each sandwich — both sides.
Gently press the buttered sides of the sandwich into the crushed pretzels so they stick. Press lightly but evenly for full coverage.
Heat a skillet over medium-low. Grill each sandwich for 2–3 minutes per side, until golden brown and the pretzels are toasty and crisp.
Slice, sprinkle with a pinch of flaky salt (optional), and serve hot!

Notes
Erren’s Top Tips
Keep the heat on the lower side so the peanut butter has time to melt before the pretzels overbrown. If the pretzels are not sticking well, gently press them in again right before the sandwich goes into the pan. Use a nonstick or well-seasoned skillet to prevent the pretzel crust from catching.
Variations & Add-Ins
Swap the jam for strawberry preserves or raspberry jam for a more intense fruit flavor. Add thin banana slices inside the sandwich for a classic peanut butter upgrade. Use almond butter or cashew butter for a different nutty profile.
Storage & Freezing
These sandwiches are best eaten right away while the crust is crisp. They do not store or freeze well once grilled, as the pretzel coating softens over time.
