Crumb Cake

The world needs more crumb cake. I mean how could your day go wrong if you start it out with a piece of this dreamy and decadent, over-the-top Crumb Cake? How I wish I could have this every day for breakfast.
You’ll love then generous layer of crisp, buttery, cinnamon laden crumbs atop that pillowy-soft, moist cake that’s swirled with notes of vanilla and an ever so light tang from the sour cream. This is one of my favorite breakfast cakes, like ever.
I’m a crumbaholic. If it has crumbs I need it, and this is overloaded with them to the max! I just love the contrast of a fluffy cake next to a dense crumbly crumb.
Last year I attempted several times to make a crumb muffin and it just never worked for me because the crumbs would either end up swallowed up by the muffin or all spread out to the edges (which made since because I never used a super tall cupcake liner to keep everything intact).
Luckily, things worked out much better in cake form. This cake turned out to be the best crumb cake I’ve ever had and I already can’t wait to make it again!

- In the bowl of an electric stand mixer fitted with the paddle attachment, whip together butter and granulated sugar until pale and fluffy. Mix in egg and vanilla. In liquid measuring cup used to measure milk, whisk together sour cream with milk.
- Add in 1/3 of the flour mixture to the butter mixture and blend just until combined, then add 1/2 of the milk mixture and mix just until combined. Repeat process once more, then end by mixing in last 1/3 of the flour mixture until nearly combined. Scape down sides and bottom of bowl using a rubber spatula and fold batter to fully incorporate.
