How To Make Blueberry Coffee Cake
There are just two simple steps to this sour cream coffee cake – the batter and the crumb topping. Here are a few tips that will help you make the cake perfectly every single time.
Sour Cream Coffee Cake Batter
When you make the batter, whisk the dry ingredients together first. Then, in another bowl, use an electric mixer to beat the sugar and butter until it is light and fluffy.
Add the eggs and sour cream to the bowl with the butter mixture. Next, gradually add the dry ingredients and keep mixing until the batter is smooth.
Finally, gently fold in the blueberries. You need to be very gentle so that the blueberries don’t dye your entire cake batter blue.

Make The Homemade Crumb Topping
Now you are ready to make the walnut crumb topping!
Just whisk the flour, sugar, walnuts, and cinnamon together until they are really well combined. You might have to let the butter soften before you do this step.
Use your fingers to create a crumble with this mixture.
Now you are ready to place the batter into the greased baking dish and sprinkle the crumb mixture on top.
