Step-by-Step LEGO Brownie Tutorial
These brownies are so easy to whip up that even the kids can help. Just follow the step-by-step directions below, and you’ll have a tray full of cute LEGO blocks in no time.
1. Prep Your Brownie Station
Start by lining a baking sheet or tray with parchment paper. This will keep things neat and make it easier to chill your decorated brownies later.
Unwrap your brownies and place them on the lined tray. If you’re using homemade brownies, bake them in a pan and cut them into rectangles once cooled. The rectangular shape is what gives it that classic LEGO brick vibe!
2. Divide and Tint the Frosting
Next, divide vanilla frosting into three small bowls. This is where the fun begins!
Add a different color gel food coloring to each bowl—one blue, one green, one yellow. Mix until you get bold, vibrant colors that match the M&Ms you’ll be using. You can adjust the shade by adding more if needed.

This step is not only satisfying but also gives you that perfect match between the topping and decorations for a seamless LEGO look.
3. Frost the Brownies
Using your butterknives, coat each brownie with a single color. You’ll want to make four brownies for each color, so you end up with 12 total.
Try to spread the mixture evenly across the top of each rectangle brownie, covering edge to edge. This will give your LEGO bricks a clean, polished look.

4. Add the M&Ms
Time to design! Take six matching pieces and gently press them into the colored topping on each brownie. Space them evenly, just like the pegs on a real LEGO brick.
The colors should coordinate with the topping to achieve the perfect LEGO look. So if the brownie is blue, add blue pieces. The same goes for green and yellow.
This step is like the cherry on top—but better, because it’s chocolate!

5. Chill and Set
Once all your brownies are designed, place the tray in the fridge to chill for about 30 minutes. This helps everything set so the decorations stay in place until it’s time to serve.
Chilling also gives the surface a slightly firmer texture, which makes these treats even more satisfying to bite into.

Tips for Making LEGO Brownies
These brownies are already easy to make, but here are a few extra tips to make your treat even more brick-tastic:
- Use gel food coloring for bolder, brighter colors that won’t water down your topping.
- Match the topping colors to the chocolate pieces for that authentic LEGO vibe.
- Pre-cut your brownies into uniform rectangles before decorating to maintain a consistent LEGO look.
- Want to customize your brownies? Try different color combinations using your favorite shades. The possibilities are endless!
Perfect for Every Occasion
This isn’t just a dessert—it’s a craft, a conversation piece, and a party highlight all rolled into one. These LEGO brownies are perfect for:
- Birthday parties (especially a LEGO birthday party)
- Bake sales
- After-school snacks
- Playdates
- DIY treat tables
- Themed birthday celebrations
And honestly? They’re also great for grown-up LEGO lovers who want a fun throwback treat that tastes as good as it looks.
