This Buttermilk Coffee Cake has cinnamon streusel all over the top and in the middle of the cake. It is made with lots of tangy buttermilk to keep it moist for days.

I love using buttermilk for baking. It’s thick and tangy and keeps baked goods moist for days. I usually send all the baked goods I test on the weekend with my husband to work on Monday or Tuesday. But this Buttermilk Coffee Cake, I kept munching on it for breakfast the whole week, and it stayed moist until the very last slice. View Post
