Cinnamon-Streusel Coffee Cake

Cinnamon-Streusel Coffee Cake

I don’t know about you, but when I was a kid there were special moments that would always happen in the brisk changes between fall and winter, and my favorite was waking up to morning homemade coffee cake. The warm and toasty aromas of cinnamon that would dance in the air just brought such peace and joy to those beautiful slow mornings, so I want to share a little bit of that beauty here with you.
