It’s Monday. And I think brownies are in order.

Did you know that you can make brownies in your slow cooker?? Seriously. Right there in your beloved crockpot. The key to getting the edges nice and chewy – but not overdone – and the middle super fudgy is to use a super high-tech device called a aluminum collar…

Ha! Gotcha. It’s literally the opposite of high-tech. Take a few big sheets of tin foil from your drawer, fold them and press them against the sides of your slow cooker to make a ring.

Ta-da!

I shared these with my father – the ultimate lover of all things chocolate – and he practically inhaled them. Texted me three times that week to say he was savoring every last piece. They are soooo yummy and I just really can’t get over the fact that they are made in the crockpot.

Slow cooker brownies. This world is. awesome.

Ingredients 

  • 1 ¼ cups flour
  • ¼ cup unsweetened cocoa powder
  • ¾ teaspoon baking powder
  • ½ teaspoon salt
  • ½ cup butter
  • 1 ½ cups semisweet chocolate chips
  • 1 cup sugar
  • 3 large eggs
  • 2 teaspoons vanilla
  • optional: 1 cup semisweet chocolate chips

Instructions 

  • First, use aluminum foil to make a “collar” to go inside your 6-quart slow cooker – this will keep the edges of your brownies from getting burned while the middle finishes baking. There is no perfect way to do this – just use a few sheets of foil, folded several times, and line the inside of your slow cooker. (See picture in post). 
  • Once you have the inside lined with a ring of foil, spray the whole inside with nonstick spray. Place a sheet of parchment paper in the bottom, inside the foil collar. (See picture)
  • In a small bowl, whisk together flour, cocoa, baking powder, and salt. Set aside. 
  • Place butter and chocolate in a medium microwave-safe bowl and microwave in 30-second increments, stirring after each, until chocolate is melted and smooth. Add sugar; stir to combine. Stir in eggs and vanilla until smooth. 
  • Add flour mixture and chocolate chips and stir just until combined (do not overmix). Transfer batter to slow cooker.
  • Cover and cook on low for 3 hours. Uncover, turn the slow cooker off and allow to cool in the slow cooker for 1 hour. Remove (by lifting the parchment out) and allow to set completely before cutting into bars and serving.

Notes

*Other sizes of slow cookers make work for these brownies but you’ll need to keep an eye on the cooking time.

    What size brownie pan did you use? 9 x 13 inch pan?

    1. Tiffany says:

      These brownies are made in a 6-quart slow cooker 🙂

    I followed the recipe exactly, 6 quart crockpot, and after 4+ hours on low they’re still *super* wet. Middle is liquid and edges are solidified on top but *very* soft and toothpick comes out wet from anywhere on it. However, my thermometer says it’s 175F in the wettest spot so technically that’s safe to eat in spite of the eggs. Was I supposed to just let it harden up and just let it be wet but harden as it cools?

    1. Tiffany says:

      I’m sorry this happened. Adding 15-30 minutes may do the trick. You can also let them cool fully in the slow cooker for 1 hour, then lift them out and cool completely in the fridge for a couple hours. Next time, you may need to plan to overcook. Continue on low for the 15-30 minutes more (checking with a toothpick for doneness) then use a towel or paper towel under the lid to absorb condensation. Hope this helps and you have better luck next time!

    I made these last night my family made them disappear in minutes lol. I added the carmal bites instead of chocolate chips and I also used Ghirardelli cocoa powder it was so rich and delicious the only thing I can say is to double or triple the recipe so that there is more to go around.

    Loved this recipe! I didn’t want to turn on the stove and take out all the pans I store there because I was very lazy, so this recipe saved me! My parents and siblings loved it.

    I have now made these five times! Perfect everytime. My slow cooker is super hot so it only takes me 2 hrs and 15 mns. This time I used chocolate orange and some orange extract and rind instead of vanilla. The result was amazing, yummilicious choc orange brownies!! My friend couldn’t believe I didn’t switch on the oven haha

    I made these brownies today and what can I say!! I’m pleasantly surprised how good they turned out to be.. crisp on outside and gooey in the middle. Never going to make them any other way now. Thank you so much!

    Tried these tonight and loved them! Cooked on low for 3 1/2 hours and cooled for just 30 mins because we couldn’t wait any longer. Crackly on the top and fudgy just like brownies should be. Thanks for the recipe!

    These were unique and fun and SO DELICIOUS! Totally doing it again. Great with ICE CREAM and toppings.

      What isn’t great with ice cream and toppings is the real question! 😉 All joking aside- excited to hear that you guys loved this recipe! Thanks for your feedback, Melissa!
