What Makes These Blondies So Good?

The secret to these blondies is the combination of melted butter and brown sugar, which creates that rich, chewy texture everyone loves. Unlike brownies, blondies let the buttery, caramel-like flavor shine, making them the perfect base for colorful mix-ins.

The M&M's add little pockets of chocolate with a satisfying crunch, while the sprinkles make every slice feel extra festive. They're simple additions, but together they turn an everyday blondie into a dessert that's perfect for celebrating.

Tips for Perfect Blondies

Don't Overmix

Once you add the flour, gently fold the batter until everything is combined. Overmixing can make the blondies dense instead of soft and chewy.

Let the Butter Cool

Allow the melted butter to cool for a few minutes before adding the eggs. This helps everything mix together smoothly.

Add Extra M&M's on Top

Before baking, press a handful of extra M&M's onto the top of the batter. Not only does it make the blondies look bakery-worthy, but you'll also get colorful chocolate in every slice.

Cool Before Slicing

I know it's tempting to dig in while they're warm (I've definitely been guilty of that!), but letting the blondies cool helps them set and gives you clean, beautiful squares.

Storage

Store leftover blondies in an airtight container at room temperature for up to 4 days.

To freeze, wrap individual blondies tightly and place them in a freezer-safe container for up to 3 months. Thaw at room temperature before serving.
