Lemon-Lime Coffee Cake

Pin It

Lemon-lime sodas are okay. I can take them or leave them...usually I leave them. I do, however, like lemon and lime pastries - like lemon bars or key lime pie. I cannot promise that this coffee cake will taste like either lemon bars or key lime pie, but I will say that it is a scrumptious breakfast or afternoon treat. If you want more lemon flavor in your cake, then try adding 1 teaspoon of lemon extract.

---

Instructions
Generously grease a 9x13 pan. Heat oven to 350° F. For this recipe, I used fresh lemon juice and fresh lime juice.


For the streusel
Combine all ingredients in a bowl except walnuts. Using a pastry cutter or two knives, cut butter into dry ingredients until crumbly. Add walnuts and stir thoroughly. Refrigerate until needed.


For the cake
In a bowl, combine unbleached white flour, whole wheat flour, salt, baking powder, lemon zest, and lime zest. Set aside. In a mixing bowl, cream butter and sugar until fluffy. Add eggs one at a time stirring well after each. Add sour cream and stir thoroughly. Add flour mixture ½ cup at a time stirring well after each. Stir in lemon zest. Batter will be thick. Pour into greased pan and top with streusel. Bake for 35-40 minutes.

For the icing
Combine all ingredients adding lime juice one tablespoon at a time. Drizzle over cooled cake.
