Crockpot PB Cup Swirl Cake – This cake is gooey, rich and over-the-top delicious! My friends and I are doing such a fun collab together! We are sharing our favorite crockpot recipes. This was fun for me not only because it was a dessert, but I love Reese’s PB cups and this turned out just like one!! It was my first time making it and I’ll definitely make it again.
