Crumb Cake aka Coffee Cake is a delicious treat that works for breakfast, afternoon tea, or dessert! Featuring a buttery crumb topping, swirls of cinnamon, and a sprinkle of confectioners’ sugar, this moist cake will have you licking the streusel topping crumbs from the plate. Make this for your next brunch or lazy weekend and I promise you’ll be dreaming of the flavor all week!

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 the 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, ever. Plus, you probably have most of the ingredients already.

I’m a crumbaholic. If it has crumbs I need it, and this crumb cake recipe 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 sense because I never used a super tall cupcake liner to keep everything intact). I was constantly adjusting the amount of streusel but was never quite satisfied with the crumbly topping. I tried yellow cake mix, adding chocolate chips, and so many things. But finally, I made THIS!

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! I love it warm out of the oven, reheated in the microwave, or even just at room temperature. You could store leftover pieces in the freezer (wrapped in plastic wrap or aluminum foil) and just thaw them one at a time for a decadent breakfast.

Instructions

  • Preheat oven to 350 degrees. Butter an 8 by 8-inch baking dish then line with two sheets of parchment, butter parchment (alternately you can just butter and lightly flour the dish if you don't care to lift out the whole cake).
  • For the crumbs:
  • In a mixing bowl whisk together brown sugar, granulated sugar, cinnamon and salt. Pour in melted butter and stir to combine.
  • Slowly add flour and mix with wooden spoon or a spatula until no streaks of flour remain. Set aside to rest while cake batter is prepared.
  • For the cake:
  • In a mixing bowl whisk together flour, baking powder, baking soda and salt for 20 seconds, set aside.
  • 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.
  • Pour batter into prepared baking dish and spread into an even layer. Break crumb mixture into pea size crumbs and drop evenly over batter.
  • Bake in preheated oven until toothpick inserted into center comes out free of batter and cake doesn't sink when touched in center, about 32 - 35 minutes. Cool in cake pan 10 minutes, then using parchment overhang lift cake from pan and cool on a wire rack. Store in an airtight container.

    I made this cake and the crumbs didn’t turn out like yours. I followed the recipe exactly but the crumb topping turned out more like paste. Please let me know what I did wrong. Thanks!

    • Ashley

      At least I am not the only one that thought that!
      I did my crumbs twice thinking I messed up!
      This sucks…a waste of ingredients!

    • Becky Bridgewater

      This happened to me aswell so I made extra crumble and sprinkled it on top!

    • Vicky

      I initially had the same issue, but I found two (different) suggestions: 1. Use cold, cubed butter and work it into the other ingredients with a pastry blender. This takes some effort, as you do not want an un-mixed topping; or 2. Make as directed, but stick the finished product in the fridge until you’re ready to use it. Break/scrape with a fork to get it back to crumbs, if necessary. Hope this helps!

  • Becky

    Just made this and it’s in the oven right now. Can’t wait to try some! :D the uncooked mixture definitely tasted good! :)

    Hi! I love the way this crumb cake looks on your site! However, when I made this recipe the crumbs sank into the cake during baking. :( also, even though I measured everything right, but my crumbs were more moist than/not as crumby as yours shown prior to baking… I am not sure why the sinking happened and I’d love a response! I made another crumb cake recipe yesterday that also resulted in sunk in crumbs… Please let me know why this could be happening!

      It likely just wasn’t cooked through all the way in the center which would cause them to sink. Also I recommend breaking the crumbs up in to really small little pieces, they’ll start out in bigger crumbles.

    • Stephanie

      Mine too. My crumbles weren’t crumbly either. They were more moist than anything

  • miki

    i made this crumb cake this past weekend and it was absolutely amazing. i especially love that it only makes a 8×8 pan instead of a full one. thank you so much for this wonderful recipe!!!

  • Jenna

    This crumb cake looks amazing!! Love how it doesn’t have a TON of butter in it! Definitely giving it a try :)

  • Katelyn @munchie pie

    I love crumb cake too!!! I pick all the crumbs off the tops of the cake because it’s the best part haha!

  • Vanessa

    Do you think I could replace the sour cream with Greek yogurt…and it’ll turn out just the same?

    • Jaclyn

      From what I’ve heard that’s generally fine, in my opinion I think it may not be quite as moist because sour cream has more fat than Greek yogurt.
