Introduction

These Red Velvet Marshmallow Swirl Brownies are a delightful twist on classic brownies, combining rich cocoa and vibrant red velvet flavors with a gooey marshmallow swirl. Perfect for satisfying your sweet tooth with a fun and colorful treat.

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.
Step 2: In a large bowl, mix together the melted butter, sugar, and vanilla extract. Beat in the eggs until fully combined.
Step 3: In a separate bowl, combine the cocoa powder, flour, salt, and baking powder. Gradually add this dry mixture to the wet ingredients, stirring until well blended.
Step 4: Stir in the red velvet cake mix until just combined, being careful not to overmix.
Step 5: Spread the batter evenly into the prepared pan. Dollop the marshmallow cream on top in small spoonfuls and use a knife to swirl it gently into the batter.
Step 6: Bake for 35 minutes, or until a toothpick inserted into the center comes out clean. Allow the brownies to cool in the pan on a wire rack before cutting into squares.

Tips & Variations

For an extra chocolatey depth, add a handful of chocolate chips to the batter before baking.
If you prefer a stronger marshmallow flavor, swirl more marshmallow cream or add mini marshmallows on top during the last 5 minutes of baking.
Use a sharp knife dipped in hot water to create smoother marshmallow swirls without dragging the batter too much.

Storage

Store the brownies in an airtight container at room temperature for up to 3 days. For longer freshness, refrigerate for up to a week. Reheat individual brownies briefly in the microwave to soften the marshmallow swirl before serving.

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 prepared red velvet frosting instead of cake mix?

Using red velvet frosting instead of cake mix will change the texture and sweetness. The cake mix provides dry ingredients that maintain the batter’s structure, so it’s best to stick with the cake mix as directed.

What if I don’t have marshmallow cream?

You can substitute marshmallow cream with mini marshmallows carefully pressed into the batter before baking. Keep an eye during baking as they may brown faster.
