This is one of the best cakes I’ve made in ages despite it not being the most photogenic cake. It’s not neat and dainty. It’s messy but fabulous. Yellow cake  is spiked with peanut butter, hot fudge, topped with a peanut butter glaze, more hot fudge, and sprinkled with peanut butter cups. You’re welcome. With the dog days of summer upon us, I’m all about not turning on my oven if I don’t have to. Enter an easy slow cooker cake. This isn’t the first time I’ve made dessert in a slow cooker but it’s been awhile and this cake reminded me I should do it more often.

The cake is so soft, moist, and tender from the peanut butter and hot fudge swirls that are baked inside that cake but the literal icing on this cake is the peanut butter glaze that’s swirled with hot fudge. When the glaze and hot fudge are applied to the warm cake and you dive in, it’s incredible. Warm melty peanut butter is heaven on earth. It’s a great cake to make before the start of a party because when the appetizers and dinner are finished, the cake is ready. Everyone can dig right in with spoons into this warm, gooey, rich, decadent cake. I always use slow cooker liners because they save so much cleanup time and highly recommend one for the cake.
