Blueberry Lemon Crumb Cake
This Blueberry Lemon Crumb Cake is one of the recipes that I am known for among my friends. The recipes was originally inspired by a sour cream raspberry coffee cake that I found on the Williams Sonoma site but I’ve adapted it over the years to my tastes. The sour cream really is what makes it, I think. It’s my go-to whenever I feel like surprising someone with a sweet treat!

Blueberry Lemon Crumb Cake

adapted from Williams Sonoma’s Raspberry Sour Cream Cake
3 eggs
1 cup sour cream
1 1/2 tsp. vanilla extract
1 3/4 cup flour
1 cup sugar
2 tsp. baking powder
1/2 tsp. baking soda
1/2 tsp. salt
zest of 1 lemon
1 1/2 cups fresh blueberries
Crumb Topping:
1 cup flour
2/3 cup sugar
1/2 cup butter
zest of 1/2 lemon
Preheat oven to 350 degrees.
First, make crumb topping.  Zest lemon. Mix flour and sugar, and then add butter, then zest, mixing until crumbly. Put in freezer while you make the cake. (This is an important step so that the crumbles maintain some shape while they bake).
Beat eggs, vanilla and sour cream in a medium bowl; set aside. In a larger bowl, mix all the dry cake ingredients. Slowly incorporate wet ingredients into dry ingredients.
Prepare either a 10-inch cake pan (springform is ideal) or bundt pan. I’ve actually made this into mini cakes using a muffin tin with success.
Pour batter into pan. Sprinkle berries evenly on top. Scatter chilled crumb topping on top of blueberries.
Bake for 35-40 minutes if using a 10-inch pan, 30-35 minutes if using a bundt pan. You’ll know it’s done when a toothpick comes out clean!
This cake is served best slightly warm, IMHO.  Enjoy!!
