I’ve gone through the steps I use to make my streusel in my post for Vanilla Glazed Coffee Cake Donuts. However, if you need a refresher:
Combine your dry ingredients (flour, sugar, cinnamon, and salt) in a medium-sized bowl. Add the melted butter and mix until well distributed. Set aside.
If you make these Cinnamon Glazed Coffee Cake Muffins, let me know in the comments below! Be sure to take a picture and tag it #bakeandfrost on Instagram. I love seeing your amazing photos!
