I love chocolate covered pretzels, so I was a tad excited to bake with pretzel M&Ms this weekend. Have you tried them? They are simply amazing. Sweet, salty, chocolatey, and crunchy. Enough said.

I bought a bag the other day and brainstormed some ways to use them, besides just eating them straight from the bag. I set out to bake a sweet/salty blondie. I began by browning some butter. I swear by brown butter because it adds so much depth and flavor to your baked good! Brown butter is my kitchen’s secret little ingredient. And it’s so easy! Plus, it makes the house smell incredible as it’s browning.

These mind-blowing blondies are so soft and chewy – they completely melt in your mouth. The crunchy m&ms, the salty pretzels, buttery dough – my new favorite blondie. And they are SO easy to make.

I made these with butterscotch chips, instead of the M&Ms, as well. If you’d like to make the butterscotch kind, just add 2/3 cup of butterscotch chips instead of pretzel M&Ms. Sometimes it’s hard to stir in the mix-ins because the batter is so thick, but use your arm muscles. 🙂

If you like salty/sweet, you’ll flip for these blondies.
