M&M Blondies Recipe

Happy Monday! How was your weekend? How was your Easter? We indulged in an extra lazy few days that included carrot cake for breakfast, an epic parks and rec marathon, and way too many mimosas! I’m definitely in need of a green juice/green toast detox day… but first, just one more bite of these brown butter M&M blondies 😉

These blondies are wildly delicious and super simple! To make them you will need butter, sugar, eggs and egg yolks, flour, salt, and M&M’s.M&M baking bits or M&M’s will work just fine! And I like to throw in some chocolate chips, too! But this is totally optional! The most complicated ingredient is probably the brown butter… but don’t skip it! Because it gives these blondies epic flavor! And I’ve got all of the details on how to make brown butter below!

How to Brown Butter

Brown butter is so delicious and easily made right on your stove top. All you need is a stick of butter, a pan, and some patience. The transformation from melted butter to browned butter is made by toasting the milk solids in butter so that the liquid turns a deep, rich, nutty brown. It adds a delicate, nutty taste to the blondie batter that really elevates the flavor in these blondies to a whole new level of delicious.

Tomake the brown butter you’ll simply take a stick ofunsalted butter and place it into a cold saucepan. You’ll melt the butterover medium-heat, stirring it periodically to make sure that the butter does not burn. The simmering butter will beginto foam slightly, and eventually it will begin to turn a nuttybrown color. When it has browned evenly, simply remove it from heat. Be sure to stay especially attentive at the end of the browning process to avoid burningthe butter.

Time to Bake

Once your batter is assembled, you’ll want to scrape it into a 9×13-inch baking pan and press it evenly into the pan. The batter is very thick, so the easiest way to do this is place a piece of Saran Wrap on top of the blondie batter and press it with your hands. Then pop it into the oven for about 30 minutes! I usually pull mine out at 24 minutes… but a lot of people like theirs more “well done”, so if that’s you, bake a few extra minutes. But remember, the blondies will continue to cook and firm up even after you take them out of the oven!
