Slow-Cooker Recipe: Very Chocolate Brownies

Slow-Cooker Recipe: Very Chocolate Brownies

You know how it feels when you’re craving dessert but don’t want to put too much effort into actually making it? Unless you’re a fan of Betty Crocker mixes, it’s time to turn to the slow cooker. With practically zero effort, you’ll have the aroma of fresh, homemade treats wafting through the house. These super chocolate-y brownies are a fabulous treat to enjoy without all of the fussing of mixing and baking. Welcome to the world of slow cooked brownies!

The trick to this treat is to not overcook. You want that great, cake-y texture, and too much time spent in the slow cooker will ruin that. When the brownies are done cooking, the center will look undercooked, but that’s perfectly okay. The brownies will continue to cook as they cool, and you’ll end up with a perfectly moist, well-cooked treat in the end. Keep reading below for our recipe…

Slow-Cooker Brownies


  • Cooking Spray
  • 1 1/4 cups flour
  • 1/4 cup unsweetened cocoa powder
  • 3/4 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1/2 cup unsalted butter, cut into pieces
  • 8oz bittersweet chocolate
  • 1 cup sugar
  • 3 large eggs, lightly beaten
  • 2 teaspoons vanilla extract
  • 1 cup chopped walnuts (optional)


  1. Lightly coat a 5-quart slow-cooker with the cooking spray, then line the bottom with parchment paper and lightly coat that in spray.
  2. In a small bowl, whisk together flour, cocoa, baking powder, and salt.
  3. Place butter and chocolate in a microwave-safe bowl and microwave in 30-second increments, stirring between each increment until the chocolate is melted. Add the sugar and and vanilla extract then stir to combine. Stir in the eggs, then add in the flour mixture, walnuts, and chocolate and stir until just moistened (be careful to not overmix). Transfer to a slow cooker and smooth out the top.
  4. Cover and cook on low for 3 1/3 hours. Uncover and cook for another 30 minutes. Remove the ceramic insert from the slow cooker and run a knife around the edge to loosen brownies. Let the brownies cool completely in the insert on a wire rack (about 2 hours). Turn out onto a work surface and cut into brownies.
  5. Enjoy!
