Cinnamon Bun Cake Recipe

Cinnamon buns are one of my favorite desserts, but they are time-consuming to make and require a lot of clean surface space to roll out the dough. Sometimes, you just want the taste of your favorite dessert – without all of the work!

This Cinnamon Bun Cake ended up being the perfect way to satisfy my cinnamon bun craving – using a doctored cake mix recipe with swirls of sweet cinnamon sugar baked in and a delicious, crackly vanilla frosting glaze on top. It tastes just like the inside piece of a cinnamon bun and is so easy to make that the kids can help with every step.

This sheet cake would be perfect for BBQs or potlucks – it’s low-fuss, easy to serve and I love being able to just bake my potluck contribution in a casserole dish and take it along with me. However, I can’t think of any occasion that I wouldn’t want a slice of this delicious, tender cake.

 

Personally, I’m not a big fan of nuts in cakes or cinnamon buns but if you’re a fan of them you can swirl them in along with the cinnamon sugar. I highly recommend Millican Pecan’s Pecan Pieces. I didn’t realize what a difference there could be between pecan brands, but these are so incredibly fresh and flavorful – plus I always grab some pecan coffee or their flavored pecans when I place my order.

Can you freeze this cinnamon bun cake? Yes, bake the cake in a freezer-safe container (another reason I love my Pyrex Casserole Dish), wrap and then store for up to one month. Do not add the frosting before freezing.

Recipe Variations:

  • You can make a cream cheese frosting for this cake instead of the crackly vanilla glaze described below
  • Swap out the vanilla cake mix for chocolate cake mix, caramel cake mix, pumpkin cake mix, etc, for a new flavor combination.
  • Use pumpkin spice instead of cinnamon for a fall-inspired twist
  • Divide the recipe into individual loaf pans for 3 cinnamon roll cakes
  • Swap out the oil required in the recipe for applesauce for a lower fat content
  • Use a maple extract instead of vanilla for a delicious twist

How to Make a Cinnamon Bun Cake

Preheat oven to 325ºF

Grease and line a 8″x12″ cake pan, and set aside.

Mix together the cake mix, eggs, oil, vanilla extract and greek yogurt and combine for 2 full minutes.

Pour the cake batter into the cake pan.

Stir together the brown sugar and cinnamon.

Sprinkle the brown sugar mixture over the cake batter and then use a spoon or spatula to twirl the brown sugar mixture into the cake batter.

Bake for 25-30 minutes until an inserted toothpick comes out clean.

Let the cake cool slightly before preparing the icing.

(You can apply the frosting while the cake is still warm or wait for it to be cooled completely – if warm, it will melt into the cake a bit.)

Combine the powdered sugar, half of the milk, and the vanilla (if using). Add the milk as needed to achieve your desired consistency.

Pour the frosting over your cake and smooth out with an offset spatula.
