Step By Step Directions for Grandma’s Honey Bun Cake
Prepare the Batter
In a large mixing bowl, combine the yellow cake mix, oil, eggs, and sour cream. Mix until everything is well combined.
Prepare the Filling
In a separate bowl, mix together the brown sugar and cinnamon.
Layer the Cake
Grease a 9×13-inch baking dish. Pour half the cake batter into the dish, then sprinkle the cinnamon and brown sugar mixture evenly over the top. Add the second half of the batter to cover the filling and spread evenly.

Cool and Serve
Allow the cake to cool before serving. Enjoy!

FAQs
If you ask me, this cake is even better the next day! Make it ahead of time for an easy breakfast treat, brunch, or something sweet to share with family.
A cream cheese frosting would be a great, rich addition to this coffee cake. If you’re looking for more of a topping and less glaze-feel, a frosting would make a great choice!
