Crock Pot Hot Fudge Sundae Cake
Crock Pot Hot Fudge Sundae Cake is a homemade chocolate cake that makes it’s own hot fudge sauce as it cooks! Simply delicious!
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

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!

I pinned the recipe to both my crock pot, and my cake board!
I use my Crock Pot a few times a month. I have all of the ingredients for that amazing dessert, so I will be making it very soon.
I have 4 or 5 crockpots of all different sizes. I mostly use it for roasts, stew and soups. I really need to expand my recipes!

Hi! I printed out the recipe for Crock Pot Hot Fudge Sundae Cake so I can make it sometime. I have used the crock pot for many dishes but I like chili in it the best! One of my crock pots is the old kind that just has on or off and the newer one has settings for different lengths of time but it seems to cook hotter than the old one. I am definitely going to make this soon! Chocoholic here! nancywho51@yahoo.com

I am learning to use my crock pot more. Thanks to Pinterest and all the great recipes I have found.
I have 2 crockpots but rarely use them. About all I use one for is to make a large pot of pinto beans in it and freeze them in containers. I would love to have some recipes to use. Thank you!

Oh Brandie…you are such a woman after my heart! I LOVE this recipe….I use my crockpot 2 or 3 times a month…I love making overnight breakfast dishes, like jazzing up oatmeal and potato/veggie dishes too.
I have 2 of the smallest crockpots, 2 of the original round pots & was given the set with 3 different size pots, 4-5-6qts & 1 base. I use them all @ different times. One of my favorite things is to use the 6qt for simmering roasted bones for bone soup. So many uses for them all!! Thank you for this great giveaway, would like to own this cook book

What a coincidence, we made a beef roast in the crock pot today, couldn't decide between Italian beef or French Dip so we are just leaving it as a roast for a change. I actually do have a smaller crock pot that came w/my husband haha that would be fine for this recipe, wish I had seen it earlier because as I took a little sample taste of the roast I thought it needed a little something to finish it off, you know, like a Texas Sheet cake. I could have had this going alongside and it would have been done about the time we finished eating. Next time 🙂

Yes, I have 3 crock pots and use them usually twice a week in the winter, and only once a week in the summer.
I love Gooseberry Patch cookbooks – and this one looks like a winner already!

I have one crockpot and I'm dying to use it more often. I'm always on the hunt for great recipes. The last thing I made was from pinterest and it was a slow cooker jambalayah.. it was sooo tastey but the recipe is no longer available 🙁 I look forward to using it more often, especially as I get busier!

Love my crockpot!!! I'm pretty sure we'd never eat if it weren't for that sweet thing!
Love me some Gooseberry Patch cookbooks, too!! I just have one right now ;), that I received as a wedding shower gift in 2002. Still lovin' it!!

I use mine at least once a week! Mine recently cracked while cooking and I had to replace the insert. It was only 15.00 though!
I have two crockpots, one large, and one smaller. I need to track down a 2 quart one.
I use them for almost everything, except I've never tried a cake. Shame on me.

I have started using my crock pot more and am always looking for new recipes…have fallen in love with pulled pork in the crock pot

I use my slow cooker year-round. It really gets a work-out in the Fall and Winter months and saves me from heating up the house in the Summer. I made Ranch Pork Chops last night and today it has Cheesy Broccoli soup going!!!

I have two crock pots and use them alot. Especially when it is over 100 degrees but still I keep them running! I even managed to talk a neighbor into using hers that had only been buying already prepared food and she is so happy! Hurray.
