Blueberry Sour Cream Crumb Cake

It is berry season, and this crumb cake definitely takes advantage of the beautiful blueberries that are making their appearance at farmers markets and supermarkets.  A soft crumb, juicy berries, and a sweet-tart drizzle all add up to an amazing cake.

A crumb cake is such a classic, and everyone needs to have a great recipe in their back pocket. This one is not only easy, but it is so versatile.  You can use any berry that you prefer - blueberry, raspberry, blackberry, or a combination.  Or you could leave the berries out, and use some of the crumb topping as a ribbon running through the middle of the cake. Coffee makes an amazing addition to a crumb cake, as does ginger. Other fruits are also great substitutions for the berries - apple, peach, banana, cherry, strawberry, pumpkin, and cranberries all work well.

This cake comes together fairly quickly once you have all of your ingredients measured out. As always the clean up takes longer than actually making the cake, even though I do try to clean as I go - where is that magic genie and his lamp when I need him? I love serving this cake while it is still a little warm with a great big scoop of vanilla bean ice cream. Whipped cream also works well.  Sour cream helps to make this cake so wonderfully moist, and the buttery, lightly spiced crumb topping adds a wonderful crunchy texture to the cake. And of course those amazing plump and juicy blueberries add a delicious pop to the cake. Cake for breakfast is also a good idea, right? 😊
