Cake Mix Sour Cream Coffee Cake

Sour cream makes this Coffee Cake super moist and the best part is that it starts with a cake mix. It’s so easy to make, and loaded with lots of cinnamon crumbly goodness. This breakfast cake is an instant crowd pleaser!

I love eating cake for breakfast. And I know you know I’m serious because yesterday we chatted about my lack of shame for eating all sorts of debatably inappropriate foods first thing in the morning, such as these Best Baked Apples Recipe (don’t knock it ’til you try it.)

But really, cake is on the less-weird list of breakfast foods because while admittedly I have eaten frosted chocolate birthday cake with sprinkles within 17 minutes of waking up, it’s really not that far of a stretch from the towering shortstacks that we all like to down at the local IHOP. Really? Pancakes? We didn’t even try to disguise the name on that one.

At least this coffee cake isn’t smothered in syrup, right?
Instead it’s loaded down with a cinnamon crumble topping. Oh oh oh, and that same crumble topping is rippled right throughout the center of the cake too. Raise your hand if the streusel is your favorite part?? Good. So you all know exactly what I’m talking about when I say there can never be enough streusel.

I developed this recipe as an easy-to-make totally delicious option for feeding a crowd. When family and friends are coming over, the last thing you want to do is fuss over a labor-intensive breakfast. This cake is just the thing because it starts with a cake mix and just four other ingredients. Easy peasy. And the crumble topping is a cinch to make so the prep takes only 10-15 minutes tops then it’s into the oven. Super moist and loaded with cinnamon crumble, this is an instant favorite!

Cake Mix Sour Cream Coffee Cake
Ingredients
- 1 package yellow cake mix, (mix only, not prepared)
- 1 egg
- 1 cup sour cream , (may sub plain greek yogurt)
- ¼ cup butter, melted
- 1 teaspoon vanilla
Crumble Topping
- 1 ¼ cups flour
- ⅔ cup brown sugar
- ½ cup sugar
- ½ teaspoon salt
- 1 teaspoon cinnamon
- ½ cup butter (8 tablespoons), chilled and cut into cubes
Instructions
- Preheat oven to 350 and grease a 9×13 inch baking dish with cooking spray.
- First prepare the crumble. Whisk together flour, brown sugar, sugar, salt, and cinnamon. Cut in chilled butter until crumbly. Set aside.
- Next prepare the cake. Combine cake mix, egg, sour cream, melted butter, and vanilla and mix until combined. It’s okay if the batter still has some lumps.
- Spread half the cake batter in the bottom of the greased baking dish (see note.) Sprinkle with half of the crumble mixture. Grease a rubber spatula and gently spread the remaining batter over the crumble (this takes a little finessing but it's worth it if you just work with it.) Top with remaining crumble.
- Bake for 30-35 minutes until an inserted toothpick comes out clean. Serve warm.

This is a great coffee cake. My sugGestion to anyone who prepares it is to add two eggs instead of one! *perfecTion*
DELicious! I followed the instructions, except I used 1 CUP OF PLAIN KEFIR INSTEAD OF SOUR CREAM, AND BAKED IT IN A BUNDT PAN (350 for 55 minutes and let cool 10 minutes before inverting.) It turned out perfect – THAnks for the great recipe!
I didn’t realize that I don’t own the right sized pan for this recipe, so I opted to use a bundt pan. I dropped spoonfulls of the batter, then a layer of the crumble. Dropped a second layer of the batter, only this time I used the back of a spoon coated with cooking spray, to spread the batter evenly before topping with the rest of the crumble. Baked at 350 for 50 minutes and it came out perfect!
Just made this cake. I was concerned about the batter being thick. Spread a pretty thin layer as the bottom layer and since it was hard to “spread” a full top layer I just spread dollops the best I could along the top. I was seriously worried before it went in the oven but it smelled delicious while it was baking and it came our awesome! Moist,light and tasty. I would put a little less topping on the top but overall it was great! I never put sour cream in a cake before and it did make it very moist! Thank you.
This is absolutely delicious! So light and fluffy and my husband, who hates sour cream, had no idea it was in it. He raved on it as well as our church family who had breakfast with us. The only problem I encountered was spreading the dough. I forgot to grease my spatula and it was like spreading pizza dough 🙂 My fault. Thanks for this delicious recipe which I will make often. Also, I didn’t bother making layers and it was perfect!
Tastes good but I think a smaller square pan would better. I would like a thicker cake and maybe in would be easier to spread into that size. Definitely too much topping if not layered in the middle. Two layers which would’ve taken a lot of patience that I did not have in the morning when I made the cake . And I have made many two layered coffee cakes. I probably will not make again just because I would want two layers and it was just too much of a pain to do with the thickness of the batter.
I’ve been making this recipe for years, it is my all time favorite coffee cake recipe. My recipe calls for 4 eggs and the addition of 1/2 cup water. It makes the batter thin and easier to spread on top of streusel topping. It’s a very moist coffee cake.
So worth the effort. Second time making it in a week. Don’t mind the elbow grease. Used an offset spatula dipped in water to spread the batter. So delicious!!
I tweeked it a lil, i warmed some cream cheese in microwave & added some powdered sugar & drizzled on top for the last 10 min of baking, making it like a danish. Yum yum.
Terrific & quick recipe! Just happened to have all of the ingredients on hand… it is New Year’s Day, and we wanted something yummy with our coffee, but didn’t want to leave our cozy living room. Delicious! I read the comments about spreading the batter and decided to use a pastry pipe, which worked well — you still have to finesse the spread of the batter, but it seemed to be an easy (if sticky) trick (my fiancé Marc suggested, can’t take the credit!). YUM! Deffo worth the effort for the two layers. This would work well with white or chocolate/yellow cake as well, I think? We plan to try it again soon! Happy 2017 🙂
