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.

    this is a good RECIPE but as a chief in training you have missed a few things out
    with the WALNUTS how much should i put in and what heat should i put my slow cooker

    1. Tiffany says:

      Hi John, walnuts were a typo in this recipe- thank you for pointing that out. The cooking temperate is listed, you must have just missed it. It’s listed in step 6 as low.

  2. Sea says:

    “Uncover, turn the slow cooker ova”. Over, as in upside down?

  3. Christopher says:

    When you say turn the slow cooker over does that literally mean turn it over as in upside down to cool? Onto like a benchtop or something?

  4. SBO says:

    It looks very nice, I like it.
    Thanks! Great recipe idea !

  5. Michaelone says:
