- Frost four brownies with each color, using a butter knife or small spatula to smooth the top.

- Press six M&Ms of the same color onto each frosted brownie to mimic Lego studs. Starting in the center makes it easier to space them out.

- Place the finished brownies on your prepared tray and chill in the fridge for about 30 minutes so the frosting sets.
