I love having a piece or two of this Walnut Coffee Cake with my morning coffee. I also like it for dessert. This coffee cake recipe is super easy to make as it uses a cake mix as its base.
This coffee cake recipe, while dense in texture, is super moist. This is in part thanks to the pudding mix, buttermilk and sour cream. Might sound like a weird combination if you’ve never made this type of cake but you need to give this one a shot.
Buttermilk Substitution
If you don’t have Buttermilk on hand, you can use this trick as a substitute: Add one tablespoon of lemon juice to a measuring cup. Add milk and fill to the 1 cup measurement line. Stir the mixture together and let sit for 5 minutes. Since this recipe calls for 1/2 cup you will need to adjust accordingly.
Another option is to use a cultured buttermilk blend. All you need to do is add water. I was very skeptical at first but in a pinch it works great!
