Disappearing Marshmallow Brownies
When I think of the perfect treat to share with friends or family, the Disappearing Marshmallow Brownies always come to mind. I vividly remember the first time I made these delicious brownies in my mom’s kitchen, surrounded by the comforting aroma of melted chocolate and the sweetness of butterscotch. As a child, I would sneak little bites while they were cooling, hardly able to wait until they were cut into bars. These brownies have a magical quality to them; they seem to vanish as soon as they’re served at gatherings. Every single time I bring them to a party, the plate is empty before I know it. The combination of flavors and textures creates a nostalgic experience that brings me right back to those carefree days. Perfectly chewy, decadently chocolatey, and infused with a hint of butterscotch, these brownies are a crowd-pleaser that you won’t want to miss.

What You Need for Disappearing Marshmallow Brownies

The ingredients in these brownies work together harmoniously to create a treat that’s both rich and satisfying. The key players here are the unsalted butter, butterscotch chips, and semi-sweet chocolate chips, each contributing to the deep, indulgent flavor. The mini marshmallows add bursts of sweetness, while the all-purpose flour and baking powder provide the perfect structure.
- ½ cup unsalted butter – This is the fat that adds richness and moisture to your brownies.
- 1 cup butterscotch chips – These bring a sweet, buttery flavor that complements the chocolate beautifully.
- 1½ cups all-purpose flour – The base of the brownies, giving them structure and body.
- â…” cup packed light brown sugar – Adds sweetness and a slight chewiness to the texture.
- 2 teaspoons baking powder – Helps the brownies rise slightly, creating a nice texture.
- ½ teaspoon Morton kosher salt – Enhances all the flavors and balances the sweetness.
- 1 teaspoon pure vanilla extract – Adds depth and a warm aroma.
- 2 large eggs – Provides moisture and helps bind the ingredients together.
- 2½ cups mini marshmallows – These melt and create pockets of gooeyness throughout the brownies.
- 2 cups semi-sweet chocolate chips – The star of the show, providing that rich chocolate flavor.
Disappearing Marshmallow Brownies Instructions

Making these brownies is a delightful process that fills your kitchen with mouthwatering aromas. Let’s dive into the steps!
- Preheat your oven to 350°F. Lightly spray the bottom and sides of a 9 by 13 inch pan with non-stick spray and set it aside. This ensures your brownies won’t stick, making it easier to cut them later.
- In a large saucepan over medium-low heat, melt the butter and butterscotch chips, stirring constantly. Make sure not to let the mixture darken, as this can affect the flavor. Don’t worry if it looks grainy or separated; it will still work perfectly!
- Remove the pan from heat and let the mixture cool until it’s only lukewarm. This is crucial because you don’t want to add the marshmallows and chocolate chips while it’s too hot, or they’ll start to melt.
- In a medium bowl, whisk together the flour, brown sugar, baking powder, and salt. This dry mixture will provide structure to your brownies.
- Once the butterscotch mixture has cooled slightly, add the vanilla and eggs, stirring well to combine. Make sure everything is nicely mixed.
- Add the dry flour mixture to the wet ingredients and stir until just combined. Be careful not to overmix; a few lumps are perfectly fine!
- Gently fold in the marshmallows and chocolate chips using a spatula. This step adds those delightful pockets of sweetness throughout the brownies. Remember to be gentle!
- Spread the brownie mixture into the prepared pan, smoothing it out evenly. Try not to compress it too much; you want a nice, soft texture.
- Bake in your preheated oven for about 20 minutes. Keep an eye on them to make sure they don’t overbake. The edges should be nicely browned while the center remains slightly under-baked for that chewy texture.
- Once done, let the brownies cool completely in the pan before cutting them into bars. This ensures that they set properly and makes slicing much easier.
Things Worth Knowing
- Preheating your oven properly allows for even baking, ensuring that your brownies rise correctly.
- Using a light-colored metal pan helps in achieving the perfect bake without burning the edges.
- Letting the butterscotch mixture cool before adding other ingredients prevents unwanted melting.
- Don’t overmix after adding the flour; this can lead to tough brownies instead of tender ones.
