Why We Love This Chocolate Smores Cake

With recipes like Slow Cooker Apple Cinnamon Rolls and our Slow Cooker Candy, it’s pretty obvious we love a good slow cooker dessert. However, we’re also suckers for a good smore. So, making this Slow Cooker Chocolate Smores Cake was a no-brainer! It’s: 

  • Made with just 6 simple ingredients. 
  • Bursting with chocolate flavor in every bite. 
  • Super easy to make. 
  • Perfect served warm with a big scoop of vanilla ice cream! 

Ingredients You’ll Need

For this smores cake, we kept the ingredient list as short as we could. Here’s what you’ll need: 

  • Chocolate Cake Mix + Baking Essentials – For the richest taste, we love this Ghiradelli mix! 
  • Graham Cracker Crumbs – You can find pre-made crumbs. Or, just add graham crackers to a bag or food processor, and crush them up yourself! 
  • Butter – This creates a golden brown crust with a super rich taste. 
  • Granulated Sugar – Make sure you use granulated sugar as other varieties won’t mix well. 
  • Semi-Sweet Chocolate Chips – If you prefer, you can swap the chocolate chips out for dark chocolate or even white chocolate varieties. 
  • Mini Marshmallows – We like mini marshmallows because they allow for even coverage on top. However, regular-sized or even jumbo versions can be used! If you do, we recommend breaking them into smaller pieces first. 

How to Make a Slow Cooker Smores Cake

The easiest cake you’ll ever make, all you have to do is combine the ingredients in a slow cooker, and wait! 

  1. Prepare the cake mix, and add 1 cup of chocolate chips. 
  2. Combine the graham cracker crumbs, butter, and sugar, and press them into the bottom of a buttered slow cooker.
  3. Spread the cake mix on top.  
  4. Cook on high for 2 hours. 
  5. Sprinkle the remaining ingredients on top, and cook for another 30 minutes. 
  6. Serve warm! 

Optional Substitutions and Mix-Ins

We think this smores cake is perfect as it is, but feel free to experiment with substitutes and mix-ins to make it your own! Some of our favorite variations include: 

  • Using a different cake mix such as vanilla or red velvet
  • Swapping out the chocolate chips with peanut butter chips or butterscotch instead
  • Using shortbread cookies, Biscoff cookies, or even Oreos instead of graham crackers for the crust
  • Stirring peanut butter into the cake batter
  • Mixing caramel pieces into the cake layer
  • Adding a scoop of cookie butter to the batter

  1. How do you keep the bottom from burning? We butter the bottom and follow the recipe, but there’s still 30 minutes left on the cook time and it is totally burnt on the bottom

    1. Oh no! You can try lining your slow cooker, unfortunately the time can vary with every slow cooker. Let us know how it turned out!

    1. The actual post needs to be edited. It repeats the directions for the graham cracker crust, but never mentions adding the chocolate cake batter. (the recipe does, but still, edit the post)

      1. Yes, it will definitely need more time, also, be sure you are using a large enough crockpot as it may not cook properly (ends will burn and center will be undercooked). You can leave it at the low setting for 6-8 hours.

  2. Is there a way to make this in the oven????? I have a request to make this for a friend giving birth tomorrow and don’t think sending my crock pot to her house is an option! LOL

    1. Yes, you can! Use a 13×9 baking dish, bake in the oven at 350 degrees F for 30-35 minutes. Remove from the oven and add the chocolate chips and marshmallows, bake for an additional 5-7 minutes or until marshmallows are melted and toasted.

    2. 3 stars
      It would be really nice if you guys notated in the recipe that you should use something bigger than a 6 quart. I did not see that until I just saw that my cake is burnt, and I went through the comments and saw that you recommend 7 quart or bigger. This should really be listed in the recipe.
