Ingredients

Makes one 9x13 inch pan · serves 12

Layered Base

  • 2 cups chocolate brownie or cake mix, prepared

Topping

  • 3 cups mini marshmallows
  • 1/4 cup melted chocolate, for drizzle
Contains: gluten, eggs, milk

Why this recipe works

The method of baking the base partially before adding the marshmallows ensures that the brownie layer reaches the correct internal temperature while the marshmallows remain soft and light rather than becoming scorched.

This staggered baking process is essential for achieving the distinct layers shown in the final presentation, allowing each component to cook perfectly.

Adding the chocolate drizzle after the dessert has cooled completely prevents the topping from melting away into the marshmallow layer. This technique maintains the visual appeal and ensures the drizzle adds a distinct, decorative element that provides a concentrated burst of chocolate flavor to every serving of the finished dessert.

Notes and substitutions

For the best results, use a high-quality chocolate brownie mix that produces a fudgy rather than cakey crumb. If using a cake-like mix, adjust the baking time slightly to avoid drying out the base. Ensure all ingredients, especially the eggs, are at room temperature before mixing to ensure a smooth, consistent batter that bakes evenly.

The choice of equipment is straightforward, though a glass 9x13 inch baking dish is recommended for even heat distribution.

If a metal pan is used, reduce the oven temperature by 25°F (15°C) to prevent the edges of the brownie from cooking too quickly. Always allow the dessert to cool fully before attempting to slice for the sharpest presentation.

  • chocolate brownie mix: a standard chocolate cake mix prepared according to package directions works perfectly as a base
  • mini marshmallows: large marshmallows can be cut into smaller pieces if mini ones are unavailable
