Chocolate Peanut Butter Cake – moist chocolate cake paired with peanut butter frosting and filling, topped with drippy chocolate ganache and homemade peanut butter balls, aka buckeyes. The ultimate layer cake for chocolate and peanut butter lovers!
Last week I shared one of our Christmas traditions with a recipe that came from Mr. Sellman’s side of the family – these super delish Pie Crust Cookies – oh my goodness are they good. While definitely hard to beat, I wanted to give a little love to a tradition that comes from my side of the family. My family is a tad more chocolate focused when it comes to Christmas goodies. As in, we dip anything and everything into chocolate and viola, Christmas dessert! Pretzels, raisins, nuts, Oreos and on and on. All this dipping started back in the 80’s when we were kids and the list of things we wanted to smother in chocolate seemed to grow from year to year. The one staple that always made the must-dip-in-chocolate list? Peanut Butter Balls!
My mother, two sisters and I made chocolate covered peanut butter balls every. single. year. growing up. Ah, the memories of sticky hands from rolling peanut butter into tiny balls and then hovering around the double boiler with my sisters, dipping our peanut butter balls into the melted chocolate… hoping they didn’t fall off the toothpick and drown in the chocolate. Inevitably, someone would complain that the other peanut butter balls were too messy. I cannot confirm nor deny that crazy person was me — let’s just say thank goodness we’re sisters and the love is unconditional. I love you girls!
A few years ago, it came to my attention that some of you know these little guys as Buckeyes. I think they’ll forever be Peanut Butter Balls to me. But whatever you call them, they are delicious! How can you go wrong with peanut butter and chocolate? Today’s cake captures all of those flavors and all those memories in one – somewhat outrageous and definitely chocolate smothered – cake recipe.
It all starts with the peanut butter balls. From there, we move on to a rich chocolate cake, filled and frosted with a creamy peanut butter buttercream. Then comes the chocolate ganached poured over the top and drizzled down the sides. Eight swirls of frosting create a decorative border and act as teeny tiny pedestals for the actual peanut butter balls. Because there are so many different components this cake, I went with simple recipes. So even though there are numerous steps, they are all relatively straight forward and can be broken up over several days to fit with your busy schedule. Here’s how it all comes together….
