M&M Blondies

Sharing is caring!

These M&M Blondies are fabulously buttery and chewy and have a festive look from a generous amount of mini M&M’s. You could probably even find red and green seasonal M&M’s and really make them look Christmasy.

I know it’s just after Thanksgiving and you’re probably stuffed with pumpkin pie and pecan pie and hardly in the mood to think about sweets.

But I’m ready to dive right into that holiday baking season.

Everyone thinks of cookies when it comes to holiday baking, but I really like my bars. Both brownies and blondies. They are so easy to make and they tend to keep well too. The only downside is waiting for them to cool before slicing them.

This M&M Blondie recipe is adapted from America’s Test Kitchen and I find their recipes pretty much always work and they can be a good base for trying something a little different.

I love how pretty M&M’s make these blondies look, but you could certainly use chocolate chips instead.

Those bright colors! Don’t they just cheer you up? Especially on a dreary late autumn day.

I think you’ll find these M&M Blondies are both soft and chewy with just the right amount of sweetness.
