Why I Love This Recipe
I’m a sucker for layered desserts—especially when one of those layers is brownie. What sets these apart is the buttery, melt-in-your-mouth frosting and smooth chocolate ganache that tops it off like a dream. The best part? You get all the indulgent flavor of a Baileys-style dessert without needing to use alcohol.
These are the kind of brownies that look bakery-worthy but are secretly easy to make with a box mix and a few pantry staples.
Ingredients
For the Brownies:
- 1 box brownie mix (plus ingredients listed on the box, like eggs, oil, and water)
- Replace ¼ cup water with milk or extra water to balance moisture
For the Buttercream:
- ½ cup salted butter, softened
- 1 teaspoon vanilla extract
- 2 ½ cups powdered sugar, sifted
- 3 to 4 tablespoons heavy whipping cream
For the Ganache:
- ⅓ cup heavy whipping cream
- 1 cup semi-sweet chocolate chips
- Optional: splash of vanilla or coffee extract for depth
Step-by-Step Instructions
🔥 1. Prepare the Brownies
- Preheat your oven according to your boxed brownie mix.
- Line an 8×8-inch baking pan with parchment paper.
- Prepare the batter per package instructions, swapping ¼ cup of water with milk or more water for added richness.
- Bake according to box directions.
- Cool completely in the pan before layering.
🧈 2. Make the Buttercream
- In a bowl, beat softened butter and vanilla extract until creamy.
- Gradually add in the sifted powdered sugar.
- Slowly mix in 3–4 tablespoons of heavy cream, beating until the mixture becomes light and fluffy.
- Spread evenly over cooled brownies and freeze for 10–15 minutes while making ganache.
🍫 3. Make the Ganache
- Heat ⅓ cup heavy cream in a microwave-safe bowl until hot but not boiling (45–60 seconds).
- Pour over the chocolate chips in a bowl.
- Let sit for 3–4 minutes, then stir until smooth and glossy.
- Spread evenly over the buttercream layer.
❄️ 4. Set & Serve
- Let the ganache set at room temperature for 45–60 minutes, or refrigerate for 15–20 minutes for faster results.
- Lift brownies out using parchment, slice into squares, and serve.
Tips for Success
- Chill between layers: This keeps the buttercream firm and makes spreading ganache easier.
- Use a hot knife for clean, bakery-style slices.
- Don’t overbake the brownie base—a slightly fudgy center works best with the soft topping layers.
- Customize the ganache: Add a pinch of salt or splash of vanilla extract for depth.
Serving Suggestions & Pairings
These brownies are rich and satisfying all on their own, but here are some fun ideas to round them out:
- Pair with a hot espresso or cold brew
- Serve alongside brownie batter dip for the ultimate chocolate lover’s dessert board
- Make them the star of a dessert spread with Oreo cream pie or grasshopper pie
Storage Tips
- Refrigerate in an airtight container for up to 5 days—the layers hold up well chilled.
- Freeze for up to 2 months. Wrap tightly in plastic wrap, then foil. Thaw in fridge overnight.
- Let come to room temp for 10–15 minutes before serving for the best texture.
