Brown Sugar Crumb Cake Is the Ultimate Twist On A Classic!

If you are a regular around here you know my affection for brown sugar. Essentially I will replace granulated sugar for brown sugar whenever I can get away with it. And today, we’re going all the way with my Brown Sugar Crumb Cake…from the cake, to the crumb topping, and the brown sugar icing that adorns the top.

What’s the Difference Between Crumb Cake and Coffee Cake?

Essentially not much. Crumb Cake typically has more “crumb topping” than coffee cake does, but really it seems in this day and age they two cakes are fairly interchangeable. Coffee cake is a more general term and doesn’t always HAVE to have crumbs on top…but you can’t really have a crumb cake without crumb topping…so…

I get MANY comments on my Coffee Cake recipe asking “Where is the coffee in this recipe?” And in the US coffee cake doesn’t HAVE coffee in it, but is meant to be enjoyed along side of a cup of coffee? I don’t make the rules here.

Brown Sugar Crumb Topping


Crumb Topping:

  • Brown sugar. You can use either dark brown sugar OR light brown sugar in the crumb topping!
  • Salt
  • Butter. Use cold butter for the crumb topping, and a pastry cutter or your hands to form the crumbs!
  • All-purpose flour


  • Room temperature butter.
  • Brown sugar. Again, you can use either light or dark.
  • Large eggs. The size of the eggs definitely matters when baking so make sure you use large.
  • Vanilla extract
  • Baking soda
  • Kosher salt
  • Greek yogurt. You can also sub in sour cream if you have that on-hand.
  • All-purpose flour


  • Brown sugar…and for the last time use light or dark!
  • Milk
  • Butter. You will be melting this, so it can be either cold or room temperature. It won’t matter.
  • Vanilla extract
  • Powdered sugar

Is the Icing Necessary?

Well, the answer here is no. But yes. Make sense? The icing is absolutely delicious and adds another layer of brown sugar flavor and sweetness.

BUT you can skip the icing if you run out of time, or are looking for a less sweet option. You can also dust it with powdered sugar as another option!

How To Store:

I am all about a warm cake along with a cup of coffee, but this cake is just as good at room temperature as it is warm. And certainly this cake can be enjoyed for multiple days if stored properly! Just make sure it is airtight and you can keep it at room temperature for up to 3 days.

And you can certainly freeze this cake to enjoy at a later time too! Just cover it airtight. I recommend using plastic wrap to cover the pan, and then aluminum foil as an extra layer of protection in your freezer for up to 30 days.

You can thaw it out at room temperature and reheat each slice in the microwave! You can also reheat the cake in the oven. Just pop it in a 350°F preheated oven for 5 – 10 minutes until warmed through!

My breakfast dreams came true when I made this Brown Sugar Crumb Cake. It’s a rich and soft brown sugar cake topped with a thick layer of brown sugar crumbs AND a brown sugar icing!



  • 1 1/4 cups light brown sugar
  • 1/2 teaspoon kosher salt
  • 1 cup butter, cold and cut into cubes
  • 2 1/2 cups all-purpose flour


  • 1/2 cup butter, room temperature
  • 1 1/4 cups brown sugar (I use dark but you can use either dark or light brown sugar)
  • 2 large eggs
  • 2 teaspoon vanilla extract
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 cup Greek yogurt
  • 2 cups all-purpose flour


  • 3/4 cup brown sugar (you can use either dark or light, I used dark)
  • 1/3 cup milk
  • 1/4 cup butter
  • 1 teaspoon vanilla
  • 1 cup powdered sugar


  1. Preheat oven to 350°F. Lightly coat a 9×13 baking pan with nonstick spray. Set aside.


  1. In a large bowl combine all the crumb ingredients and using a pastry cutter or your hands combine the mixture until crumbs form. I usually start with my pastry cutter and then finish with my hands to form larger crumbs. Set aside.


  1. In the bowl of your stand mixer fitted with the paddle attachment mix the butter and sugar together for 2 minutes. Add the eggs, vanilla, baking soda and salt and mix for an additional minute until combined, scraping the sides of the bowl as necessary. Lower the speed of your mixer to low and In alternating additions add in the flour and yogurt, beginning and ending with the flour. Mix until smooth. Spread the batter in the prepared pan and spread the crumb mixture evenly on top.
  2. Bake for 30-35 minutes until the center is set and a toothpick comes out clean.


  1. In a medium saucepan combine the brown sugar, milk and butter on medium heat. Bring to a boil and boil for 3 minutes. Immediately remove from the heat. Stir in the vanilla and whisk in the powdered sugar until no more lumps remain. Allow the icing to cool for 10-15 minutes, whisking occasionally until it thickens a bit and then drizzle on top of the warm cake.
  2. Serve warm or at room temperature.


store airtight for up to 3 days.

I noted you can use dark or light brown sugar in this recipe. I used dark in the cake and light in the crumb and icing, but feel free to use all dark or all light.

Also, note you can add 1 teaspoon of cinnamon to both the cake and the crumb if you would like a cinnamon flavored cake.
