Say that title 5 times fast! I just couldn’t decide what to leave out. Peanut butter? Caramel? Hot fudge? Slow Cooker? Crock Pot?

Whatever, this Slow Cooker Caramel Peanut Butter Hot Fudge Cake has the longest title in history, but it’s one of my new favorite desserts!

Crockpot Caramel Peanut Butter Hot Fudge Cake is the perfect thing to make when you want a gooey hot dessert!

PIN IT NOW TO SAVE FOR LATER 

See that? That oozy caramel? It’s a Rolo.

{I know, right? I put a Rolo inside a peanut butter cake? I’m a genius.}

Now that we’re really into fall, I love using my slow cooker for dinner. (Well, at least I will be, once it stops being freaking 90 degrees. here. I mean come on Mother Nature. Give us a break please!)

I love making soups and roasts and chicken in my crockpot, but my new favorite thing to make is dessert. Obviously!

A few weeks ago I made a Slow Cooker Apple Dump Cake that rocked my world. And once I made that I started getting so many other ideas. Chocolate cake, chocolate lava cake, pie…and so many more. This is my first installment in my #crockpotallthethings winter dessert series: a Caramel Peanut Butter Hot Fudge Cake.

#notreallyaseries #butmaybe #lotsofideas

This Crockpot Caramel Peanut Butter Hot Fudge Cake is warm and gooey and awesome with ice cream!

This recipe could not be easier. I actually whipped it up one morning before school and when I got home from the gym my morning snack was ready. {Kidding. Um, sort of?}

You make this with a bowl and a spoon, no mixer needed. The peanut butter batter comes together fast with some easy stirring and it gets spread in the bottom of your slow cooker. Then you press some Rolos in the top, because Rolos are good.

Then comes the hot fudge part: cocoa and sugar are mixed with boiling water and poured slowly over the cake. While it cooks the chocolate sauce becomes thick, like hot fudge.

My cake took just about 2 hours to cook on high power. Remember though – all slow cookers are different. Mine has settings for low power (12 or 10 hours) and high power (4 or 6 hours). I put mine on high for 6 hours and after 2 it was done. If you’ve never made a cake in the crockpot before, be sure and start checking it after about an hour. It might be done in an hour and a half, or it could take up to 3 hours.

Once it’s done you let it cool a little bit, then scoop big bowls with ice cream. Because you can’t have hot fudge cake without ice cream!

Seriously, where has crockpot cake been all my life??

Slow Cooker Caramel Peanut Butter Hot Fudge Cake

Prep Time:
20 mins
Cook Time:
2 hrs
This peanut butter hot fudge cake is filled with Rolos and is baked in the slow cooker! There's nothing better than a bowl of this topped with ice cream for a warm and gooey dessert.

Ingredients

  • 1 cup all purpose flour
  • 1 cup granulated sugar — divided
  • 1 teaspoon baking powder
  • 1 cup milk
  • 1/3 cup vegetable oil
  • 1/2 teaspoon vanilla
  • 3/4 cup peanut butter
  • 15-20 Rolos or similar caramel candy — unwrapped
  • 3 tablespoons unsweetened cocoa powder
  • 1 cup boiling water

Instructions

  1. Stir the flour, 1/2 cup sugar, and baking powder in a large bowl. Add milk, oil, and vanilla and stir until smooth. Stir in the peanut butter.
  2. Spray a 6 or 7-quart slow cooker with cooking spray. Spread the batter in the bottom of the crockpot. Press Rolos evenly across the top of the batter.
  3. Whisk 1/2 cup remaining sugar and cocoa powder in a medium bowl. Slowly whisk in the boiling water. Carefully and slowly pour the chocolate water over the top of the cake. Do not stir.
  4. Cover and cook on High for about 2 hours, or until a toothpick comes out clean. Cool slightly before serving. Serve with ice cream or whipped cream.
  5. Note: all slow cookers cook differently. My crockpot has a “High 6 hour” setting, which is what I used. Be sure to check on your cake after 1 1/2 hours and it may take up to 3 hours, depending on how your machine cooks.

  1. Made this last night, my first slow cooker cake! I’m not a big cake person but the ooziness of this recipe was enough for me : ) The cooking time is right on, I used my small crockpot which cooks pretty hot and it was ready within two hours. I added a little Nutella to the chocolate as well, I can think of tons of variations that would be delicious! Thanks.

  2. Seriously delicious. I made this for our day-after-Thanksgiving dessert party, because it didn’t require the oven and it seemed like a worthwhile gamble. My twenty-year-old daughter took two bites and said, “Always make this, for everything, forever, from now on.” Terrific recipe and couldn’t be easier. Thanks for posting it!

  3. I am very excited to try this! I have never baked in a crock pot before. To ensure the cake is not under or over baked, what is the test? Dry toothpick method? Or….?
    With the fudgy sauce on it, will I be able to tell when it’s done?
    Thank you so much for your guidance, AND for sharing your awesome recipes! I’m so glad to hav found you! : )

    • If I remember correctly with this cake, the sauce floats to the bottom, so you can somewhat see when it’s done. The center shouldn’t be jiggly, and you can try the toothpick test. Just make sure to watch the edges – often those get done first in the crockpot, especially if one side cooks faster.

  4. I had a dinner party the other week, kitchen was too busy with food to bake desert so I whipped this up in the crock pot and couldn’t believe how it turned out! I already loved my crockpot but now even more knowing that amazing deserts can be made with it =) Great recipe!

  5. I am bringing this to a crock pot party. Should I cook ahead and just warm it there? Sounds delicious!

    • It depends how long before you want it served. If the party is long and you don’t want it served until the end, then that’s fine. You can also make it at home and then just warm it up on a low setting there!

  6. Looks amazing!! I am serving a really large group. Have you or anyone else ever tried to double it?

  7. Wow these look amazing! I can’t wait to try them. I’m gluten sensitive so I’ll be trying to make it gluten free. Hope it will still turn out!

  8. Can this be done on the oven? If so, what temp and for how long?

  9. OMG…..dinner for 20 last night and this was the dessert. First time I’d made it.
    Had my big slow cooker going with slow cook pulled pork and fresh buns happening, ginormous lasagne prepped two days ago warming and garlic bread.
    Prepped this easily and quickly, doubled mixture and popped it on, walked away and four hours later there was NONE left and they loved it!!!! Thankyou (PS I’m a macros girl and it didn’t fit in my numbers for the day, but our guests all loved it and it smelt sooo good. I changed a few things (added a little salt to make it salted caramel and 1/2 sugar was brown sugar in mine)
