Frosted Cinnamon Roll Cake
My Granny makes the best cinnamon rolls in the whole world. True story!
However, I only get to enjoy them every now and then because we live so far away. And while I can get the recipe easily enough, my Granny’s cinnamon rolls are a true labor of love. Everything has to be just right or they don’t turn out! My Granny always makes them perfectly…
Me…not so much…
SO…this cinnamon roll cake is the next best thing! I love it because it doesn’t try to compete with a classic cinnamon roll, but rather puts its own spin on things.
Plus it is absolutely covered in thick, rich frosting – the best part right??
Make a batch for your next special event or you can freeze them so they’ll be ready to enjoy anytime!

Even though this dessert is made from scratch, it’s pretty easy to make!
Start by making your batter, then spreading into the bottom of your pan. Cover with a generous layer of the cinnamon roll filling.
Then top with rich cream cheese frosting – my favorite part!
TIP: These cinnamon roll bars also freeze well! I keep mine on the parchment paper (pre sliced) and put a piece on top and slide it into a bag and vacuum seal it. Then we just defrost and heat in the microwave for 20 seconds. YUM!
