Introduction
These Red Velvet Marshmallow Swirl Brownies combine the rich, chocolatey flavor of classic brownies with a vibrant red velvet twist and a gooey marshmallow swirl. Perfect for a special treat, they’re moist, flavorful, and delightfully fudgy with a fun, creamy topping.

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, whisk together 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 just until combined, being careful not to overmix.
- Step 5: Spread the batter evenly into the prepared pan. Dollop the marshmallow cream on top in several spots, then use a knife to gently swirl it through 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 a nutty crunch, sprinkle chopped pecans or walnuts on top before swirling in the marshmallow cream.
- Use cream cheese frosting swirled into the batter for a tangy contrast to the sweet marshmallow.
- Be careful not to overmix once you add the dry ingredients to keep the brownies tender and fudgy.
Storage
Store the brownies in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to one week or freeze individual portions wrapped tightly for up to 3 months. Reheat briefly in the microwave to soften the marshmallow swirl before serving.
