If I could, I would just eat the cinnamon brown sugar topping on this coffee cake by itself, with a spoon. But it’s even better when it’s paired with moist sour cream cake! That combination of super soft cake and slightly crunchy streusel is a match made in heaven.

And let’s not forget the fact that this recipe is made with cake mix! I love gussying up a cake mix to make it taste homemade and I guarantee that no one will guess your shortcut when they taste this coffee cake!

How to Make Cake Mix Sour Cream Coffee Cake

1. Prepare

Preheat your oven to 350ºF and grease a 9×9 or 9×11-inch baking pan with non-stick cooking spray.

2. Make the Crumble

Whisk together the flour, brown sugar, sugar, salt, and cinnamon in a bowl, then cut in the chilled butter until the mixture is crumbly.

3. Make the Cake Batter

Combine the cake mix, water, egg, sour cream, melted butter, and vanilla in a large bowl and stir until combined.

4. Assemble the Cake

Spread half of the cake batter in the bottom of the greased baking dish, then top with half of the crumble mixture. Top the crumble layer with dollops of the remaining cake batter, then spread with a greased rubber spatula. Sprinkle with remaining crumble.

5. Bake the Cake

Bake the coffee cake for 30 to 35 minutes, or until a toothpick inserted into the center of the cake comes out clean.

6. Make the Optional Glaze

While the cake is baking, combine the glaze ingredients in a small bowl. Drizzle the glaze over the cake after it’s cooled for about 10 minutes.

Hint: You can make this recipe in cupcake tins for individual cakes if you like!

FAQ

Is there a difference between coffee cake and crumb cake?

The two are very similar, but there’s a key difference: coffee cake is more cake, less crumble; crumb cake is more crumble, less cake.

Does coffee cake actually have coffee?

No! There’s no coffee in coffee cake. But you can definitely have a cup of coffee with it. Or maybe some Pumpkin Spice Cold Brew?

Top Tip

Make sure you use cold butter in the crumble. That’s how you get the crumble texture, instead of it being one thick layer of sugar and cinnamon.

    good thing I didn’t look at pan size. I assumed it was for 9 x13 and I know all that dough would not fit in 9×9. Also correct the melted/ chilled butter. I’m an old German cook who knew better than melt the butter for streusel… otherwise good cake. quicker than my old recipe from scratch……

    Ingredients call for melted butter but directions call for chilled… figure out which it’s supposed to be and fix it. What a stupid I’d recipe.

  3. The ingredients call for MELTED unsalted butter. But, then the recipe says chilled. I’m glad I read the whole thing before melting that butter too.
