Introduction

These Double Decker Triple Stuffed Christmas Brownies bring a festive twist to classic brownies by layering rich chocolate and bright yellow cake batters with hidden pockets of caramel and chocolate kisses. Perfect for holiday gatherings, they are both indulgent and fun to make.

The image shows a stack of four square dessert bars on a white marbled surface with a white tiled wall background. Each bar has three visible layers: a top golden brown crumbly layer, a thick dark chocolate middle layer mixed with colorful candy pieces in red, green, and yellow, and a bottom layer that appears to be a baked cookie dough with chocolate chunks embedded. The top layer is slightly cracked with swirls of chocolate visible, and the candy pieces add bright spots of color to the overall rich brown tones. To the right, a stack of white plates is slightly visible. photo taken with an iphone --ar 4:5 --v 7

Ingredients

1 box brownie mix + required ingredients as per package
1 box yellow cake mix
1/4 cup vegetable oil
1/3 cup milk
1 egg
20 Rolos or caramel filled kisses
20 Hershey’s Kiss Hugs
3/4 cup holiday M&Ms (for batter)
1/4 cup holiday M&Ms and sprinkles (for topping)

Instructions

Step 1: Preheat your oven to 350°F and line a 13 x 9 inch cake pan with parchment paper.
Step 2: Prepare the brownie mix according to the package directions in a large bowl.
Step 3: In a separate large bowl, combine the yellow cake mix with 1/4 cup vegetable oil, 1/3 cup milk, and 1 egg until smooth.
Step 4: Fold 1/4 cup of the holiday M&Ms into each batter to add a festive crunch.
Step 5: Pour about one-third to half of the brownie batter into the prepared pan, spreading it evenly to the edges with a spoon.
Step 6: Gently arrange the Hershey’s Kisses and Kiss Hugs over the brownie layer without pressing them into the batter.
Step 7: Carefully pour the remaining brownie batter over the chocolate pieces, spreading it as evenly as possible without disturbing the kisses.
Step 8: Drop large spoonfuls of the cake batter on top of and between the brownie batter, filling holes and covering as much of the kisses as possible, but do not cover all the brownie batter. There may be some cake batter left over.
Step 9: Use a toothpick to gently swirl the brownie and cake batters together, which also helps conceal any exposed Hershey’s Kisses.
Step 10: Sprinkle the top with the remaining 1/4 cup of holiday M&Ms and some sprinkles. Bake at 350°F for 25 to 35 minutes, or until a toothpick inserted near the center comes out mostly clean.

Tips & Variations

For extra gooey centers, use caramel-filled Rolos wrapped in foil to ensure they don’t melt too thin.
Swap holiday M&Ms for plain or peanut M&Ms if preferred.
Try using different flavored cake mixes like red velvet or spice cake for a seasonal variation.
Use a toothpick gently to swirl batters without overmixing, preserving distinct layers and marbling effects.

Storage

Store the brownies in an airtight container at room temperature for up to 4 days. For longer freshness, refrigerate for up to a week. When reheating, warm individual pieces gently in the microwave for 10–15 seconds to restore the melty texture.

How to Serve

Twelve square pieces of swirled brownies sit on a black cooling rack over a white marbled surface, each piece showing a top layer with light brown and dark chocolate swirl patterns creating a textured look. Red and green candy-coated chocolates are scattered sparsely on the surface of several brownies. The brownies have a slightly rough crust with a dense, moist inside visible on a few edges, and all pieces are evenly cut, with one piece missing from the bottom right corner.

FAQs

Can I make this recipe from scratch without using boxed mixes?

Yes, you can substitute homemade brownie and yellow cake batters for the boxed mixes. Just prepare each batter separately and follow the layering and swirling steps as directed.

What if I don’t have holiday M&Ms?

Regular M&Ms, mini chocolate chips, or festive sprinkles work well here. The M&Ms add both texture and a pop of color, but feel free to adapt based on what you have.

Ingredients

Scale

Brownie Layer

1 box brownie mix + required ingredients as per package
3/4 cup holiday M&Ms (for batter)

Cake Layer

1 box yellow cake mix
1/4 cup vegetable oil
1/3 cup milk
1 egg
1/4 cup holiday M&Ms (for batter)

Fillings & Toppings

20 Rolos or caramel filled kisses
20 Hershey’s Kiss Hugs
1/4 cup holiday M&Ms and sprinkles (for topping)

Instructions

Preheat and Prepare Pan: Preheat your oven to 350°F (175°C) and line a 13 x 9-inch cake pan with parchment paper to prevent sticking and ensure easy removal.
Make Brownie Batter: In a large bowl, prepare the brownie mix according to the package instructions. Once ready, fold in 3/4 cup of holiday colored M&Ms for a festive touch.
Make Cake Batter: In a separate large bowl, combine the yellow cake mix with 1/4 cup vegetable oil, 1/3 cup milk, and 1 egg. Mix well until smooth. Then fold in 1/4 cup of holiday M&Ms.
Layer Brownie Batter: Pour about one-third to one-half of the brownie batter evenly into the prepared pan, spreading it gently with a spoon all the way to the edges.
Add Fillings: Place the 20 Hershey’s Kiss Hugs and 20 caramel-filled Rolos or caramel kisses gently on top of the brownie batter. Do not press them into the batter; just let them sit on top.
Add Remaining Brownie Batter: Carefully pour the remaining brownie batter over the kisses, spreading it as evenly as possible without moving the candies underneath.
Add Cake Batter Dollops: Drop large spoonfuls of the yellow cake batter on top of and between the brownie batter areas, filling in holes and covering as much of the candies as possible without completely covering the brownie batter sections. You might have some cake batter left over.
Swirl Batters: Using a toothpick, gently swirl the brownie and cake batters together to create a marbled effect and to cover any exposed tops of the kisses.
Add Toppings and Bake: Sprinkle a scant 1/4 cup of holiday M&Ms and festive sprinkles on top. Bake at 350°F for 25 to 35 minutes or until a toothpick inserted near the center comes out with a few moist crumbs but no raw batter.
Cool and Serve: Allow the brownies to cool completely in the pan on a wire rack before slicing into squares. Enjoy your festive double-decker triple stuffed Christmas brownies!

Notes

Use parchment paper to ensure easy removal of the brownies from the pan.
Do not press the candy kisses into the batter; placing them gently on top helps maintain the layers.
Swirling batters creates a beautiful marbled effect and ensures the flavors combine.
Adjust baking time slightly if using a different size pan or if your oven runs hot or cool.
Let brownies cool well before cutting to avoid breaking apart.
