What’s more comforting than warm, gooey chocolate chip bar cookies full of M&Ms? The last time my mom and I were at the lake, she said, “I think you’re going to bake us M&M bar cookies,” so I hopped right up and did just that. They were so good, I just had to share the recipe with you!
This felt very vintage Rose Table to me because we went through a major bar cookie phase when I was young. (And by phrase I mean, oh, my entire childhood.) They’re just so fast and easy compared to individual cookies! Plus the texture is just fabulous.
This is a one-bowl recipe that could not be easier. You don’t even have to let butter soften! This recipe calls for melted butter. I love these warm from the oven when the chocolate is all melty but they stay soft for days. They’re great to pack for picnics and lunchboxes too because of their flat, sturdy shape.
I think this *might* be the only bar cookie on The Rose Table. Comment and let me know if you’d like to see more bar cookie recipes!
