Crumb Cake

Jump to Recipe Print Recipe

If you like coffee cake but wish there was a more equal cake-to-topping ratio, then you need to try crumb cake. The cake is lightly sweetened and has a sturdy texture. It’s not a cake that could stand alone. It NEEDS the large crumb topping to really make it.

Crumb Cake

Crumb cake is rumored to have started in Germany as a yeast cake. Then the invention of baking powder came along and crumb cake was the American adaptation. I honestly don’t care who invented it. I’m just happy that it’s a thing, and that I can make it whenever I want.

I mean, anything that’s called a breakfast cake is okay in my book. Hmmm, maybe I need to invent a lunch cake. I can always squeeze my daily dose of veggies in at dinnertime.

When mixing the cake batter, be careful not to overmix. Once I begin adding the flour mixture, I like to do the rest by hand with a rubber spatula. Once you’ve poured the mixture into the pan, also refrain from spreading it around too much. At first, it may seem like there’s not enough batter for the 9×13 pan, but the baking powder gives it just enough rise.

Next, you can mix the topping all in one bowl. Just melt the butter in a medium sized microwave safe bowl, then you can begin adding the other ingredients. It comes together really quickly. The next part is a great way to get the kids involved. They can simply grab a handful of topping and use their fingers to crumble it over the top. There’s plenty to go around!

Adding the Crumb

Once the topping has been evenly distributed, just pop it in the oven for 25-30 minutes. Test with a cake tester or a toothpick or a knife and pull it out as soon as the cake tester comes out clean.

Allow the cake to cool completely and then dust with powdered sugar. If it’s not cooled yet, the powdered sugar will melt into the topping. There is an awesome product called Snow Sugar which is a non-melting powdered sugar. I used it a lot in the shop but if dusting warm things with powdered sugar isn’t a common occurrence in your house, don’t waste your money.
