I have certainly made my love for all things crumb-topped well known here at Baking a Moment!

There are SO many delicious recipes here that begin and end with streusel! Here’s just a small sampling:

But recently I realized there was a glaring omission in my recipe index.

No cinnamon crumb cake??

No no no no no. This cannot be.

So I immediately got to work baking up this total classic.

I think you are going to love it!

The cake itself is moist as can be. Of course it is, it’s made with sour cream!

But really it’s all about the crumb topping. It’s got plenty of spicy cinnamon and warm brown sugar, and there are two layers of it! One running all throughout the middle of the cake, and another thick, crumbly layer on top.

Just wait until you sink your fork into this coffee cake! All those layers together- you’re in for a real treat!

Get your mug of coffee ready!

Cinnamon Crumb Cake

Cinnamon Crumb Cake: moist sour cream cake ribboned with brown sugar & cinnamon, and topped with a thick layer of crumbly streusel. A total classic, so delicious with a cup of coffee!

Prep Time 25 minutes Cook Time 35 minutes Total Time 1 hour
Serves 8     adjust servings

Ingredients

For the cinnamon crumb topping:

  • 1/2 cup unsalted butter
  • 1 1/2 cups all-purpose flour
  • 3/4 cup dark brown sugar (lightly packed)
  • 2 tablespoons ground cinnamon
  • 1/4 teaspoon kosher salt

For the sour cream cake:

  • 1 1/2 cups all-purpose flour
  • 1/2 cup granulated sugar
  • 3/4 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon kosher salt
  • 6 tablespoons unsalted butter, softened
  • 2 large eggs
  • 2/3 cup sour cream
  • 1 teaspoon vanilla extract
  • juice of 1/2 a lemon
  • powdered sugar (for garnish)

Instructions

To make the cinnamon crumb topping:

  1. Place the butter in a small pot and melt over low heat.
  2. Add the flour, brown sugar, cinnamon, and salt, and toss to combine.

To make the cake:

  1. Preheat the oven to 350 degrees F, and mist a 9-inch springform pan with non-stick spray.
  2. Place the flour, sugar, baking powder, baking soda, and salt in the bowl of an electric mixer, and stir to combine.
  3. Add the butter, and mix on medium-low speed until the mixture resembles damp sand (about 2 minutes).
  4. Add the eggs, one at a time, mixing on low speed until smooth.
  5. Scrape the bottom and sides of the bowl with a silicone spatula, then add the sour cream, vanilla, and lemon juice.
  6. Beat on medium speed for about 1 1/2 minutes, to aerate the cake batter and build its structure.
  7. Transfer half the cake batter to the prepared pan.
  8. Top with half the topping, then spread the remaining batter on top (layers of cake batter may seem thin, but they will puff up as they bake).
  9. Sprinkle the remaining cinnamon crumb mixture on top, then bake the cake for 30 to 40 minutes, or until a toothpick inserted in the thickest part of the cake comes out clean or with a few moist crumbs.
  10. Cool completely, then dust with powdered sugar for garnish.
