This Peanut Butter Chocolate Banana Bark turns three simple ingredients into an easy frozen snack with layers of sweet banana, creamy peanut butter, and crisp chocolate.
Instead of arranging individual banana rounds, the bananas are pressed into one thin, even layer. That makes the finished bark easier to spread with peanut butter, coat with chocolate, freeze, and break into irregular pieces.
A sprinkle of chopped roasted peanuts and flaky sea salt gives the chocolate shell an especially good sweet-salty finish.
Ingredients
For the Banana Bark
- 3 large ripe but firm bananas
- ½ cup (128g) creamy peanut butter
- 1 cup (170g) semisweet or dark chocolate chips
- 1 tablespoon coconut oil, optional, for a thinner chocolate shell
Optional Toppings
- ¼ cup (35g) roasted peanuts, roughly chopped
- Flaky sea salt
How to Make Peanut Butter Chocolate Banana Bark
Step 1 – Prepare the Pan
Line a small baking sheet, tray, or large plate with parchment paper.
Make sure the tray will fit flat inside your freezer.
Step 2 – Make the Banana Layer
Peel the bananas and arrange them close together on the parchment.
Place another sheet of parchment paper over the bananas.
Using the bottom of a glass, measuring cup, or another flat object, gently press and smush the bananas into one connected layer, approximately ¼–½ inch thick.
Don't make the layer excessively thin or the frozen bark will become difficult to handle.
Carefully peel away the top parchment.
If necessary, use a spoon or spatula to tidy the edges and fill any gaps.
Step 3 – Add the Peanut Butter
Spread the peanut butter evenly over the flattened banana layer.
Use as much or as little as you prefer, but approximately ½ cup gives the bark a generous peanut butter layer without overwhelming the banana.
If your peanut butter is particularly thick, microwave it for about 10–15 seconds so it's easier to spread without disturbing the bananas.
Step 4 – Freeze
Transfer the tray to the freezer.
Freeze for approximately 1–2 hours, or until the banana layer is firm and the peanut butter has become solid.
This step is important. If the peanut butter is still soft, spreading warm melted chocolate over it can cause the layers to mix together.
Make the Chocolate Topping
Place the chocolate chips and optional coconut oil in a microwave-safe bowl.
Microwave in 20-second intervals, stirring thoroughly after each interval, until smooth.
Alternatively, melt the chocolate gently using a double boiler.
Let the chocolate stand for a minute or two so it's fluid but not piping hot.
Cover With Chocolate
Remove the frozen banana-peanut butter layer from the freezer.
Immediately pour the melted chocolate over the peanut butter.
Working quickly, use an offset spatula or the back of a spoon to spread it into a relatively thin, even layer.
Immediately sprinkle with chopped roasted peanuts and a little flaky sea salt before the chocolate sets.
Because the banana layer is frozen, the chocolate will begin hardening quickly.
Freeze Again
Return the tray to the freezer for approximately 20–30 minutes, or until the chocolate is completely firm.
Break Into Bark
Lift the frozen slab from the tray using the parchment.
Break it into irregular pieces with your hands, or use a sharp knife for cleaner portions.
Enjoy directly from the freezer for the firmest texture.
Chef's Tips for the Best Banana Bark
- Use ripe but still firm bananas. Very overripe bananas can become excessively wet when pressed.
- Press the bananas into one continuous layer instead of using individual rounds.
- Don't make the banana layer paper-thin.
- Natural peanut butter works well, but stir it thoroughly before using.
- Freeze the peanut butter layer until completely firm before adding chocolate.
- Let melted chocolate cool slightly before pouring it over the frozen bark.
- Add peanuts immediately because the chocolate can set very quickly against the frozen surface.
- A little coconut oil makes the chocolate easier to spread and slightly easier to bite when frozen.
- Flaky sea salt provides a great contrast to the sweet banana and chocolate.
- Keep the finished bark frozen rather than storing it at room temperature.
The Secret to Better Banana Bark
The biggest improvement is smashing the bananas into one flat layer.
With individual banana slices, every piece has rounded edges and little gaps between them. Peanut butter and chocolate can pool unevenly, and the finished bark tends to separate into individual frozen banana coins.
Flattening the bananas creates a cohesive base.
You get all three layers—banana, peanut butter, and chocolate—in virtually every bite, and you can break the finished slab into whatever size pieces you want.
The Secret to a Chocolate Shell That's Easier to Bite
Straight chocolate becomes quite hard in the freezer.
Adding approximately 1 tablespoon coconut oil per cup of chocolate chips thins the melted chocolate and creates a slightly more delicate shell.
Keep the chocolate layer relatively thin as well. A thick frozen chocolate slab can be difficult to bite through while the banana underneath is still frozen.
Delicious Variations
Dark Chocolate Sea Salt
Use 70% dark chocolate and finish with flaky sea salt.
Crunchy Peanut Butter
Replace creamy peanut butter with crunchy peanut butter for extra texture.
Almond Butter Banana Bark
Use almond butter and top with chopped roasted almonds.
Strawberry Banana
Press thin strawberry slices into the banana before adding peanut butter.
Chocolate Coconut
Sprinkle toasted shredded coconut over the melted chocolate.
S'mores Banana Bark
Add crushed graham crackers and a small amount of mini marshmallows over the chocolate.
Extra Peanut Butter
Drizzle additional warmed peanut butter over the set chocolate before the final freeze.
Make-Ahead Tips
This recipe is ideal for making ahead because it needs to remain frozen anyway.
Prepare an entire tray, freeze until completely firm, then break it into portions.
Once frozen, transfer the pieces to a freezer-safe container so you don't need to keep the entire baking sheet in your freezer.
Storage
Store the bark in an airtight freezer-safe container with parchment paper between layers.
For the best flavor and texture, enjoy within approximately 2–3 weeks.
Don't store the finished bark at room temperature. As the bananas thaw, they'll become very soft and release moisture.
How to Serve
Banana bark is best eaten straight from the freezer or after just a few minutes at room temperature.
If your freezer keeps it extremely hard, let a piece sit for about 2–3 minutes before eating. The banana will soften slightly while the peanut butter stays cold and the chocolate shell remains crisp.
Notes
- Makes approximately 10–14 pieces, depending on how you break the bark.
- The ingredient quantities are intentionally flexible; this recipe works well without precise measurements.
- Three bananas create a good small-tray batch, but the recipe can easily be doubled.
- Milk, semisweet, or dark chocolate all work.
- For a less-sweet version, choose dark chocolate and unsweetened natural peanut butter.
- Chopped roasted peanuts are optional but add excellent crunch.
- Keep the bark frozen until you're ready to eat it.
- For the most appetizing finish, leave the pieces slightly irregular so you can clearly see the creamy banana base, thick peanut butter center, thin chocolate shell, and crunchy peanuts in every broken edge.
