Chocolate Cake with Peanut Butter Icing

Yard sale season began a couple weekends ago here in Lancaster County. I’m not typically a huge yard saler, but I did go to a friend’s sale a couple Saturdays ago and found a sweet cookbook. This particular cookbook is filled with recipes from Lancaster’s Central Market, the oldest continuously running farmers’ market in the country. Now this cookbook is from the late ’80s but man, was I inspired to try some of the recipes in there! I’m always looking for new-to-me recipes and also Lancaster County favorites to share with you guys so I feel like I stumbled upon a goldmine here with this cookbook. This is the first recipe I’ve adapted and will be sharing with you.

Chocolate Cake with Peanut Butter Icing

It starts out with a pretty simple chocolate cake recipe. In this particular recipe, a cup of strong brewed coffee is used to really bring out the chocolate flavor of this cake and also bumps up the moisture level. This is definitely not a dried-out chocolate cake! And because of that very reason, it pairs so wonderfully with the peanut butter icing.

Speaking of which, there are two whole cups of peanut butter in this icing recipe. I had to tweak the original recipe to make it just right (in my opinion). It’s a thick, creamy, not-too-sweet icing that’s lip-smackin’ good. To me, it tastes like the inside of a Reese’s peanut butter cup. Seriously good stuff here.

The icing is layered thick on top of that chocolate cake…yum, it’s seriously so delicious. Mitch kept commenting on how good this cake was, which is unlike him. He usually just eats stuff and doesn’t really talk about it. But this cake must have made a big impression on him!

This is a great cake to make ahead of time because it’s even better the next day (or two) after it’s made.
