 A CHOCOLATE SLOW COOKER DESSERT

I have such a fun recipe to share today! I previewed a photo of this Crock Pot Hot Fudge Sundae Cake on facebook a couple of days ago and I was so surprised by how many of y’all were excited for me to share this one. Have you ever made a cake in your slow cooker? Did you know you could make a cake in your slow cooker? Well, it turns out you can. And it can turn out really good too!

TIPS FOR MAKING THIS SLOW COOKER CAKE:

  • For this recipe, you really need a smaller (2-3 quart) slow cooker. If the slow cooker is too large or wide, the cake may cook very unevenly and you won’t get a proper fudge layer to form. I have not tested it with anything larger so cannot tell you how it would turn out. Bake it at your own risk.
  • I have only tried this with whole and 2% cow’s milk. I have not tried it with almond or oat milk so I can’t say how those would turn out.

INGREDIENTS NEEDED: (FULL RECIPE AT THE BOTTOM OF THE POST)

  • all-purpose flour
  • sugar
  • cocoa powder
  • baking powder
  • salt
  • milk
  • oil
  • vanilla extract
  • chopped nuts (optional)
  • brown sugar
  • hot water
all purpose flour, sugar, cocoa powder, milk, water, baking powder and a white crock pot.

HOW TO MAKE CROCK POT HOT FUDGE SUNDAE CAKE:

Spray a 2-3 quart slow cooker with nonstick cooking spray. For baking, I like to use this kind that has flour in it.

In a bowl, sift together flour, sugar, 4 tablespoons cocoa powder, baking powder and salt.

I don’t own a flour sifter so I just took a long-tined fork and stirred it up real good.

 Then stir in milk, oil and vanilla extract.

Give it all a good stir until combined, then fold in nuts (if using). Spread batter evenly into your slow cooker.

In a separate bowl, combine brown sugar and remaining cocoa powder.

Stir in hot water until smooth.

Pour this mixture evenly over batter in slow cooker. DO NOT STIR.

Cover and cook on high setting for 2-2 1/2 hours (it took about  2 1/2 hours for mine to bake).

To test if it is done, stick a toothpick into the center. If it comes out clean (with no cake batter hanging on it), then it is done. Let cake stand, uncovered for 30-40 minutes before serving (this will thicken the sauce.)

On the top you will have your cake layer. Underneath that cake layer is your fudge sauce. So slice up the cake (it’s okay if it falls apart a little bit on you, this cake comes out very moist). Spoon it up on a plate or bowl. Then scoop up some of that hot fudge sauce that is on the bottom, and drizzle a bit of that on top of your cake along with a scoop of vanilla ice cream!

  1. Can you make a 9×13 cake and bake it in the oven? Always need something for Church and this would be a nice change. What temp would I put it at and how long? Maybe about the same time it takes for a 9×13 cake to bake.

    1. Hi Rosemarie! I haven’t actually tried baking this but it seems to me like you could. So I can’t give you baking times but my guess would be about those same times. If you try it, please come back and let me know how it turns out for you!

  2. WHat a great idea—To have different sizes in crockpots. I have a very large one, and I never thought of getting a smaller one as a second pot. I would love a recipe for barley soup with chopped veggies, like my mother used to make with a soup bone.. I love crockpot recipes for two people.

  3. I made this recipe last night and my family absolutely LOVE THIS!!!! I'm making it again tonight, this time I'm going to double up the ingredients for a bigger crock pot because I don't own a smaller one.

  4. Are the ingredients listed for the smaller cake or the larger cake like you made? This sounds so yummy!!! *mouth is now watering lol*

  5. I have 2 crockpots that I use at least once weekly, sometimes both at the same time. Crockpots are a great invention!!

  6. I probably use my crock pot 3 to 5 times a week. Yesterday was spaghetti sauce, today it is a balsamic roast. Love it! I use it more than any other small appliance.

  7. OMG I can't believe how many people went on & on & on about their crackpots!! I had to go through a hundred of them just to see if anyone actually made the recipe above!! I guess I'll be the first to post a review on the recipe itself. It's cooking as I write. I'll be back in an hour.

  8. I just recently dug out my crockpot again. It's sooo sweet to come home to a meal cooked after working full time!

    I made your chicken enchilad & Mexican Rice recipe last night. Both were a big hit with the family!

    I'm excited today to see how the pulled pork recipe is in the crockpot. I loved it came with the rub recipe & using Dr Pepper!

    I really want to try the Chocolate Sundae Hot Fudge cake recipe in the crock pot! My family will be surprised to have dessert plus I have all the ingredients at home for it!

    I love the option that I can create a shopping list & plan meals on your site! My hubby was impressed when we did the food shopping this week & it was all printed out!

    I cant wait to try more! Have a great day!

  9. I'd like to use my crockpot more often. I just recently dug mine out. It sure is sweet to come home to a day of working full time to have your meal cooked!!!

    Today I'm excited as I'm cooking the pulled pork with the rub recipe & Dr Pepper! I cant wait to see how it turns out!

    Last night I made your Chicken Enchilada & Mexican Rice recipes. They were a bit hit with the family!

    I cant wait to try your chocolate cake recipe for the crock pot!!

    I love the shopping list option your site offered! Even my hubby was impressed as I had it all planned out with the list!

    Thank you & have a great day!

  10. I have two crock pots, one large, one small. We use them at least once a week, stews, soups, roasts, BBQ beef, taco, chili. My family would go hungry won't them!

  11. I dont use my crockpot as much as I'd like to. I just started back as it's soooo sweet to come home to a prepared meal after working full time. I just threw in one of your recipes for the pulled pork with a rub recipe you gave and the Dr Pepper soda! I cant wait! Last night I made your chicken enchiladas & mexican rice recipes! They were a hit with the family! Thank you and I cant wait to try new more recipes! I love your website & the shopping lists it helps create! Even my hubby was impressed as we shopped for all our meals for the next two weeks!! Have a great day!

  12. I have 4 different sizes of crockpots, only using one about once a month—would like to slow cook more often.

  13. I love my crockpots! I use them often and would love a new cookbook! I have pinned the recipe. I have been a big fan of Gooseberry patch for a while and have tweeted about you both! My email is tupchurch@yahoo.com

  14. I babysit my grandchildren, who live 30 minutes away, so the crock pot is my greatest helper on those days! Love that dinner is ready when I walk through the door, and that a warm meal awaits!! LOVE my crock pot!!
