Chunky Monkey Stuffed Croissants (Sweet Brunch Bake, 20 Minutes)

These chunky monkey stuffed croissants are what happens when I raid the fruit bowl, the chocolate stash, and the peanut butter jar all before 9 a.m. Flaky, buttery pastry cradles ripe banana slices, pools of melting chocolate, toasty walnuts, and a soft dusting of cinnamon, then everything gets a lazy ribbon of warm peanut butter poured over the top. It tastes like a hug from a Parisian bakery that somehow moonlights as an ice cream shop, and it comes together faster than you can brew a second cup of coffee.

Fun fact: the name “chunky monkey” started life as a Ben & Jerry’s ice cream flavor created in 1988, inspired by a fan letter suggesting bananas, walnuts, and chocolate. Nearly forty years later, that same trio still makes people smile, and it turns out those flavors love a warm croissant just as much as they love a freezer pint.

Why this recipe works

• Store-bought croissants do the heavy lifting, so there’s zero dough drama on a sleepy morning.
• The banana caramelizes just a touch in the oven, mellowing into something almost custardy against the melty chocolate.
• A quick peanut butter drizzle stitches every bite together with salty-sweet richness that feels more grown-up than a plain glaze.
• Start-to-finish it lands in about 20 minutes, which means brunch guests think you fussed and you know you didn’t.
• It’s endlessly flexible: swap the nuts, change the chocolate, go dairy-free, sprinkle in berries. The base always works.

Ingredients

• 4 large butter croissants (240 g), preferably a day old
• 2 tablespoons unsalted butter, melted (28 g)
• 2 ripe bananas, sliced (240 g)
• ½ cup semi-sweet chocolate chunks or chips (85 g)
• ¼ cup chopped walnuts (30 g)
• ¼ teaspoon ground cinnamon (0.5 g)
• ⅓ cup creamy peanut butter (80 g)
• 2 tablespoons heavy cream or milk (30 ml)
• 1 tablespoon honey or maple syrup (15 ml)
• Powdered sugar, for dusting (optional)

Instructions

Step 1: Heat the oven and prep the pan

Turn the oven up to 375°F (190°C) and line a rimmed baking sheet with parchment paper. That single sheet of parchment is your best friend here, because any chocolate that decides to escape will slide right off instead of welding itself to your pan.

Step 2: Butterfly the croissants

Using a sharp serrated knife, slice each croissant lengthwise, stopping just before you cut all the way through so they open like a little book. Keeping them hinged makes stuffing easier and keeps the filling tucked inside where it belongs.

Step 3: Brush with butter

Dip a pastry brush (or the back of a spoon) in the melted butter and paint the inside cut surfaces of each croissant. This tiny step adds richness, encourages a golden interior, and helps the filling snuggle into the pastry as everything bakes.

Step 4: Layer the chunky monkey filling

Tuck banana slices along the bottom of each croissant, then scatter chocolate chunks and chopped walnuts on top. Finish with a whisper of cinnamon. Resist the urge to overstuff, a modest layer bakes evenly and gives you all four ingredients in every mouthful.

Step 5: Bake until golden and gooey

Gently close the croissants and arrange them on the prepared sheet with a bit of breathing room between each one. Bake for 12 to 15 minutes, until the tops are deeply golden, the edges are crisp, and you can see chocolate winking out of the seams.

Step 6: Drizzle and serve

While the croissants bake, warm the peanut butter, cream, and honey together in a small saucepan over low heat (or microwave in 15-second bursts), stirring until silky and pourable. Drizzle generously over the hot croissants, shower with powdered sugar if you like, and serve immediately while everything is still warm and melty.

Pro tips for the best chunky monkey stuffed croissants

• Reach for slightly stale croissants. Fresh ones can go a little soft in the middle, while day-old pastry crisps beautifully and holds the filling like a champ.
• Slice the bananas the same thickness (about ¼ inch) so they soften evenly instead of turning to mush in some spots and staying firm in others.
• Warm the peanut butter drizzle slowly. High heat can make natural peanut butter split, and a broken drizzle is a sad drizzle.
• Toast the walnuts in a dry skillet for two minutes before adding them if you want a deeper, more praline-like crunch.
• Finish with a pinch of flaky sea salt over the peanut butter, it makes the chocolate taste twice as chocolatey.

Frequently asked questions

Can I make chunky monkey stuffed croissants ahead of time?

Yes, you can slice, fill, and cover the croissants the night before, then refrigerate them on the parchment-lined sheet. In the morning, bake straight from the fridge and add a minute or two to the baking time.

How do I store and reheat leftovers?

Pop leftover croissants in an airtight container in the fridge for up to two days. To bring them back to life, reheat in a 325°F (165°C) oven for 8 to 10 minutes. Skip the microwave, it turns the pastry rubbery.

Can I make this recipe nut-free?

Absolutely. Leave out the walnuts and swap the peanut butter drizzle for a warm cookie butter or sunflower seed butter drizzle. Toasted coconut flakes or mini marshmallows are lovely add-ins for extra texture.

What’s the best chocolate to use?

Semi-sweet chocolate chunks are my go-to because they melt into little pools without becoming overly sweet. Dark chocolate (around 70%) works beautifully if you want something less sugary, and milk chocolate makes it feel more like dessert.

Can I make a vegan version?

Yes. Choose vegan croissants, use plant-based butter for brushing, swap the chocolate for a dairy-free variety, and replace the cream with coconut cream and the honey with maple syrup in the drizzle. The result is just as gooey and indulgent.
