  • flour - I use all-purpose baking flour for this recipe
  • baking powder
  • butter - I use unsalted
  • semisweet chocolate bar or semi-sweet chocolate chips
  • sugar - granulated regular sugar
  • Dutch-processed cocoa powder - Dutch processed gives a smoother, less bitter overall flavor

How to cook the cake in the slow cooker:

**scroll down for full ingredients list and printable directions**

  1. Spray the inside of a 2 ½ quart to 5 quart slow cooker with non stick spray.
  2. Mix the flour and baking powder together in a bowl.
  3. Melt the butter and chocolate in the microwave in another bowl. Whisk in ⅔ cup of sugar, 3 TBS of cocoa, vanilla, salt, milk, and egg yolk. Add the flour mixture and stir until thoroughly mixed. Pour the batter into the slow cooker and spread it evenly.
  4. In a medium bowl, whisk together the ⅓ cup sugar, ⅓ cup brown sugar, ⅓ cup cocoa and hot water until completely mixed together. Pour the mixture over the batter in the slow cooker. - DO NOT MIX.
  5. Cover and cook for 2-3 hours on HIGH, checking at the 2 hour mark. The cake should look done, and the sides of the cake will be away from the sides of the slow cooker.
    • The larger your slow cooker, the shorter the cooking time will be. (I cooked in a small 2.5 quart slow cooker and it took exactly 2 hours)
  6. Remove the top, be careful not to drip water from the lid onto the cake, and allow to cool for 30 minutes. Serve topped with ice cream or whipped cream.

    So decadent! Today is National Drink Wine Day (apparently? I must believe it's true) and this super chocolately cake would be perfect for a little extra indulgence with a glass of wine tonight. Or three 🙂

    Hi! Do you think this recipe would work if I doubled it? I have a six quart slow cooker and girls' weekend coming up in a couple of weeks. 🙂

    Thanks!!

      Yes, you might want to cook it a little bit longer. I can't really say because I haven't tried it, but I think it could be done!

    I first came across this while looking for chocolaty desserts to make for Valentine's Day. Even added it to my 12 affordable ways to say 'I love you' post. So now I'm ready to try this and I can't wait. Chocolate and slow cooker...oh yeah!

    Thank you so much for this insanely chocolatey recipe! We are going through a major kitchen/LR/DR remodel, so we are relying on the crock pot and Instant Pot and grill for meals...no oven. I needed a crock pot dessert recipe for my daughter's 18th birthday. For dinner, I made an Instant Pot pasta recipe that kind of failed (burn light went on, pasta was stuck to bottom of pan yet not cooked yet -- auugh! I should really read the user manual...). This delicious and easy dessert saved the day! My family seemed a little dubious about a crock pot cake, but they *loved* it! My daughter was so happy to have a yummy dessert on her special day. (In case you're wondering why we didn't take the girl out to eat for her 18th, she had been out super late the night before at prom, and just wanted to sleep and relax all day.) I followed the directions to a T and served with lots of vanilla ice cream. Yum!!

      WOW!!! I am SO happy it turned out great for y'all! We went through a kitchen remodel last year and lets just say, I know how you feel! I have lots of instant pot recipes too, that are seriously delicious and will not give you the burn notice! You can check them out here! Good luck with the rest of your remodel and I hope everything goes smoothly!
