Blueberry Sour Cream Coffee Cake

This coffee cake is light and fluffy. I decreased the sugar from the original recipe by half a cup and still think it is sweet enough. You can use cubed fresh pears in this recipe instead of blueberries. You can also use pecans instead of walnuts in the topping. This would be nice for brunch along side a savory dish.

  1. Thank you, Ellen, for all the extra effort you went to with the photos. I love seeing all the pictures. They are so helpful in understanding your recipe!

  2. Yum, thanks for posting. I just found some blueberries in the freezer from last Summer and now I have a terrific way to use them. Robin

  3. Yum - I would like a piece right now with my morning coffee!!!! That looks SO good. Love that there is lemon zest in this.

  4. Ellen, this looks perfect! And I love that you reduced the sugar (something I do a lot). Wish I had some blueberries on hand this morning. Delicious!

  5. Can I substitute frozen blueberries?

    1. Yes, Barbara, I used frozen but I let them thaw in a colander and emptied the colander onto paper towels to get the excess liquid off the thawed blueberries.

  6. Thank you so much for this delicious recipe. I will love it!

  7. Oh my goodness Ellen, first chance I get I am making this. Thank you for another delicious recipe.
