Ingredients You’ll Need

To make these delicious bars, gather the following ingredients:

1 cup unsalted butter, melted
1 cup granulated sugar
1 cup brown sugar, packed
2 large eggs
2 teaspoons vanilla extract
2 cups all-purpose flour
1 cup cocoa powder
1 teaspoon baking powder
1/2 teaspoon salt
1 cup dark chocolate chips
1 cup milk chocolate chips
1 cup mini marshmallows
1 cup white chocolate chips

Serving Size: 12 bars

Prep Time: 20 minutes

Cook Time: 30 minutes

Step-by-Step Instructions

Preheat the Oven: Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking pan or line it with parchment paper for easy removal.
Mix the Wet Ingredients: In a large mixing bowl, combine the melted butter, granulated sugar, and brown sugar. Mix until well combined. Add the eggs and vanilla extract, and whisk until smooth.
Combine Dry Ingredients: In another bowl, sift together the flour, cocoa powder, baking powder, and salt. Gradually add the dry ingredients to the wet mixture, stirring until just combined.
Add Chocolate Chips: Fold in the dark and milk chocolate chips, reserving a handful for topping later. Spread half of the batter into the prepared baking pan, smoothing it out evenly.
Add Marshmallows: Sprinkle the mini marshmallows over the batter layer, followed by the remaining batter. Gently spread it over the marshmallows, being careful not to disturb them too much.
Bake: Bake in the preheated oven for 25-30 minutes, or until the edges are set but the center is still slightly gooey. Remove from the oven and sprinkle the white chocolate chips and reserved dark and milk chocolate chips on top.
Cool and Cut: Allow the bars to cool in the pan for at least 15 minutes before lifting them out using the parchment paper. Cut into squares and enjoy!

My Pro Tips for Success

Chill the Dough: If you find the dough too sticky to work with, chill it in the refrigerator for about 30 minutes before spreading it in the pan.
Experiment with Flavors: Try adding crushed nuts, such as walnuts or pecans, for added crunch. You can also mix in some peanut butter chips for a different flavor profile.
Serve Warm: For an extra indulgent treat, serve these bars warm with a scoop of vanilla ice cream on top.
Storage Tips: Store any leftovers in an airtight container at room temperature for up to a week, or freeze for longer storage.

What I Serve With This Recipe

These Gooey Triple Chocolate Marshmallow Crumble Bars pair wonderfully with:

A scoop of vanilla ice cream for a classic dessert experience.
A drizzle of caramel sauce for an extra layer of sweetness.

FAQs (From My Kitchen to Yours)

Can I use different types of chocolate? Absolutely! Feel free to substitute with your favorite chocolate varieties, such as dark chocolate or even flavored chocolates.
How do I know when the bars are done baking? The edges should be set, and the center should still be slightly soft. It will firm up as it cools.
Can I make these bars ahead of time? Yes! You can prepare them a day in advance and store them in an airtight container.
What if I don’t have cocoa powder? You can substitute with an equal amount of all-purpose flour, but the chocolate flavor will be less intense.
