A super simple cake made all in the slow cooker, this peanut butter cake with chocolate candies will surely be everyone’s new favorite. Simply mix everything together, add to your slow cooker, and a few hours later, you’ll have a puffed, delicious cake to enjoy!

For me, there is something so welcoming and homey when using the slow cooker. Coming home after hours at work or being at home and smelling something wonderful cooking in the kitchen – without slaving away for hours – is like walking into grandma’s house and knowing you’ll be happy. Mom’s use of a slow cooker was best with her chili. For some reason, we always had chili in the slow cooker, and I still get so excited when I walk into her house and smell that soup.

While she never made a dessert with her slow cooker, I think she may try this one. In most circumstances, I would say, what’s the point of making this in a slow cooker? But recently, I was in a hurry to leave the house to run some errands, so I didn’t have time to wait on the oven. After a little recipe tweaking, I dumped the batter in the slow cooker and went on my way. A few hours later, I returned to a delicious-smelling peanut butter cake, perfectly warm and ready for my bowl. Topped with ice cream, this has become a classic for me.

To make it fitting for Valentine’s Day—which I will be celebrating by eating this whole cake—I mixed in some of my favorite candy. With or without the candy, or the holiday for that matter, this cake is the homey hug you have been waiting for.

Ingredients

  • 1 ¼ cups all-purpose flour
  • 1 cup granulated sugar
  • 2 tsp baking powder
  • ½ tsp baking soda
  • ½ tsp kosher salt
  • cup vegetable or corn oil (I prefer grapeseed)
  • 2 tbsp unsalted butter melted
  • 3 large eggs
  • 1 tsp vanilla extract
  • ½ cup peanut butter
  • 2 cup unwrapped candy (optional)

Instructions 

  • Sift together the flour, sugar, baking powder, baking soda, and salt and set aside.
    1 ¼ cups all-purpose flour, 1 cup granulated sugar, 2 tsp baking powder, ½ tsp baking soda, ½ tsp kosher salt
  • In a large bowl or glass measuring cup whisk the oil, butter, eggs, and vanilla extract. Add the peanut butter and whisk until smooth and incorporated.
    ⅓ cup vegetable or corn oil (I prefer grapeseed), 2 tbsp unsalted butter, 3 large eggs, 1 tsp vanilla extract, ½ cup peanut butter
  • Fold in the dry ingredients until no dry streaks remain.
  • Fold in candy, reserving ½ cup for topping.
    2 cup unwrapped candy (optional)
  • Prepare a 4-6 quart slow cooker by spraying cooker with baking spray. Press in one 12×15 inch piece of parchment paper, creasing edges so it can lay flat. Spray parchment paper.
  • Pour in prepared batter and top with lid. Cook on high 3 ½ to 4 hours. The cake will be set in the middle and a toothpick will come out clean.
  • In the last 30 minutes of cooking, top with reserved candy and finish cooking.
  • When finished, serve warm with ice cream.

    On a iPhone, the website is not printer friendly… I was wondering how much batter would I have to make for a 9×13 slow cooker. I think this would make a wonderful potluck dessert!
