Pillowy soft slow cooker apple cinnamon rolls are cooked up in a crock pot for the perfect set-it-and-forget-it breakfast or dessert for a crowd. This is perfect for the fall and holiday season!**The cook time will largely depend on the size of your crock pot. Larger crock pots will cook faster since the cinnamon rolls will be cooking in an evenly layer. The smaller the crock pot, the thicker this mixture will be. If this is the case, you'll need to begin stirring the mixture every 45 minutes after the first 2 hours of the cook time lapses. In my small crock pot it took around 4-5 hours on low.
Add the apple mixture ingredients to a bowl - butter, brown sugar, and cinnamon. Heat in the microwave stirring occasionally until the brown sugar has dissolved, about 1 minute.
Peel apples, slice and dice into 1" pieces. Add apples in with the brown sugar mixture, tossing to coat the apples evenly.
Cream Cheese Frosting
Whisk the icing ingredients until smooth.
Cinnamon Roll Assembly
Combine the heavy cream, egg, brown sugar, vanilla, and cinnamon into a medium bowl. Whisk until smooth and egg is incorporated.
Cut each cinnamon roll into four pieces. Place half of the cinnamon roll pieces evenly into the bottom of the slow cooker. Add half of the apple mixture on top.
Pour the heavy cream mixture over the top of the cinnamon rolls. Top with remaining pieces of cinnamon rolls and the remaining apple mixture (and their juices).
Drizzle 1/3-1/2 cup over the top of the cinnamon rolls in the crock pot.
Slow Cook Cinnamon Rolls
Cover and cook on low for 2-2.5 hours or until cinnamon rolls are cooked through (see notes below for varying cook times based on the crock pot size).
Drizzle the cinnamon rolls with the remaining cream cheese frosting. Serve by scooping out portions into bowls.
Notes
NOTE: The cook times for these crock pot cinnamon rolls vary drastically depending on the type of slow cooker you have. Crock Pot sizes can vary from 2-10 quarts (and beyond). If you have a smaller slow cooker, the cinnamon roll layers will be thicker which can cause the cinnamon rolls on the bottom and sides cook faster (or even burn) before the middle and top cook through. To fix this, you'll need to cook these longer than two hours, and you'll need to gently stir this mixture every ~30-45 minutes or so, folding the mixture so the top and middle can reach the bottom of the pan. Continue to cook, checking on the mixture every 30-45 minutes until it's cooked through without any raw dough. This may take 4-5 hours on low. Don't be tempted to spike the temp to high in order to get a faster cook time. This will cause the cinnamon rolls to burn.
