Chocolate Rum Cake that is a moist and decadent cake that tastes better the longer it sits. The chocolate rum syrup soaks into the cake and keeps the cake soft and tender.

I’ve heard that in Germany there is a tradition that each afternoon, you enjoy a cup of coffee and a slice of cake. Kaffee und kuchen. I feel like since I will be living in Germany this summer, I need to start embracing the German way of life as soon as possible. This tradition will begin today and every afternoon henceforth.

It sounds like a perfectly lovely thing to do to, doesn’t it? I like the idea of taking a break in the middle of the workday to refresh and regroup. And it doesn’t hurt that I really like coffee and cake. This is a win-win.

It isn’t a specific cake that is consumed, it can be any cake you like. If you are like me and like a boozy cake, my chocolate rum cake recipe is the one for you. Maybe this is less of a weekday workday cake and more of a lazy weekend cake?

Regardless, this cake is incredible. It is a super moist (sorry, I know that is a polarizing word, but it is what it is) cake that actually gets better after it sits for a day or two.

This recipe is a little different than most cake recipes. You actually let this cake cool completely and put it back in its cake pan. You pour over a chocolate rum syrup and let it soak in overnight. You then turn the cake back out and dust it with powdered sugar before you serve it. It packs a (rum) punch and is an excellent cake to go along with a steamy cup of coffee.

      Glad you like it. Make sure to grease the pan well with butter and flour (or cocoa). Let the cake cool for 20–30 minutes, then loosen the edges with a knife. Invert onto a plate and tap gently. If it sticks, cover with a warm towel for a few minutes to create steam.

      Here’s your recipe in grams for accuracy:

      Cake
      – 290g flour
      – 400g sugar
      – 80g cocoa powder
      – 10g baking soda
      – 5g salt
      – 100g eggs
      – 250g buttermilk
      – 8g vanilla
      – 200g oil
      – 60g rum
      – 180g hot coffee

      Chocolate Rum Syrup
      – 115g butter
      – 120g water
      – 150g sugar
      – 5g salt
      – 25g cocoa powder
      – 5g vanilla
      – 60g rum
      – 15g powdered sugar
