Prepare an 11x15 sheet pan by lining it with parchment paper to prevent sticking.
Peel and slice the bananas into approximately ¼-inch thick rounds, arranging them in neat rows on the prepared baking sheet. Place the pan in the freezer while preparing the next component.
3 Medium Bananas
Add the peanut butter to a microwave-safe bowl and heat for 45 seconds to 1 minute until it becomes pourable. Be careful not to overheat.
1 Cup Creamy Peanut Butter
Remove the banana-lined pan from the freezer and pour the warm peanut butter over the banana slices, avoiding the very edges. Use a rubber spatula to spread it evenly, then return the pan to the freezer.
Place the chocolate chips in a microwave-safe bowl and heat in 30-second intervals, stirring between each interval, until completely melted and smooth (about 2 minutes total).
8 Ounces Dark Chocolate Chips
Take the pan from the freezer and pour the melted chocolate over the peanut butter layer, saving a small amount for drizzling. Spread the chocolate evenly with a spatula.
Quickly sprinkle the broken pretzel pieces over the chocolate before it sets, distributing them evenly across the surface.
½ Cup Mini Pretzels
Use the remaining melted chocolate to create decorative drizzle lines across the top using a rubber spatula or spoon.
Return the pan to the freezer for at least 2 hours or until completely frozen and set. Once firm, break the bark into irregular pieces and serve immediately.
Notes
Quality Matters: Use high-quality chocolate chips like Ghirardelli for the best flavor and melting properties. Better chocolate makes a significant difference in the final taste.
Banana Selection: Choose bananas that are ripe but still firm. Overly ripe bananas will be too soft to provide a sturdy base for your chocolate bark. Even Layers: Take time to spread each layer evenly for consistent texture and flavor in every piece of bark.
Temperature Control: When melting chocolate, be careful not to overheat it. Chocolate can seize or become grainy if it gets too hot, so stick with short intervals and frequent stirring.
Work Quickly: Have all your toppings ready before melting the chocolate, as you'll need to add them while the chocolate is still wet for proper adhesion.
