Introduction

These Red Velvet Marshmallow Swirl Brownies combine the rich chocolate flavor of classic brownies with the vibrant, tangy twist of red velvet cake and a gooey marshmallow swirl. They are a delightful treat perfect for parties or a cozy dessert at home.

The image shows a close-up of three thick square red velvet brownie pieces arranged on a white marbled surface with parchment paper partially underneath. Each brownie has two visible layers: the bottom layer is rich, moist, and deep red with a dense texture, and the top layer shows creamy white and red swirled cream cheese with a smooth, slightly glossy appearance, creating a marbled pattern. Crumbs from the brownies are scattered around on the surface, adding a rustic look. The photo taken with an iphone --ar 4:5 --v 7

Ingredients

1/2 cup unsalted butter, melted
1 cup granulated sugar
2 large eggs
2 teaspoons vanilla extract
1/3 cup unsweetened cocoa powder
1/2 cup all-purpose flour
1/4 teaspoon salt
1/4 teaspoon baking powder
1/2 cup red velvet cake mix
1/2 cup marshmallow cream

Instructions

Step 1: Preheat your oven to 350°F (175°C) and grease a 9×9 inch baking pan to prevent sticking.
Step 2: In a large bowl, combine the melted butter, sugar, and vanilla extract. Beat in the eggs until the mixture is smooth.
Step 3: In a separate bowl, whisk together the cocoa powder, flour, salt, and baking powder. Gradually add this dry mixture to the wet ingredients, mixing until just blended.
Step 4: Stir in the red velvet cake mix until the batter is evenly combined without overmixing.
Step 5: Spread the batter evenly into the prepared pan. Dollop the marshmallow cream on top and use a knife to swirl it gently through the batter to create a marbled effect.
Step 6: Bake for 35 minutes, or until a toothpick inserted into the center comes out clean. Let the brownies cool completely in the pan on a wire rack before cutting into squares.

Tips & Variations

For extra gooey marshmallow swirls, add a few more dollops of marshmallow cream before baking.
Try adding chopped nuts like pecans or walnuts to the batter for added crunch.
Use a sharp knife warmed in hot water to create more defined swirls without dragging too much batter.
Substitute the red velvet cake mix with your favorite flavored cake mix for a different twist.

Storage

Store the brownies in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to a week or freeze for up to 3 months. Reheat in the microwave for 15–20 seconds for a soft, melty treat.

How to Serve

The image shows three thick square pieces of rich red velvet brownies with a creamy white and red marbled swirl of cream cheese frosting on top. The bottom layer is a moist, deep red cake with a slightly crumbly texture, while the top layer displays a smooth, glossy cream cheese swirl in different patterns over the red base. The brownies are placed on white parchment paper that sits on a dark, worn baking tray, with some red crumbs scattered around. The close-up view highlights the contrast between the vibrant red and bright white colors and the soft texture of the dessert. Photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I use regular cake mix instead of red velvet?

Yes, you can substitute with any cake mix flavor you like, but red velvet provides a distinct color and flavor that pairs well with the chocolate brownie base.

Is marshmallow cream necessary, or can I use marshmallows?

Marshmallow cream is easier to swirl and creates a smooth texture. Chopped marshmallows can work but may not melt evenly and could create uneven blobs.
