Recipe Tips

  • The foil will help prevent the outside of the brownie from burning while allowing it to cook correctly. It will also mean you don’t need to clean your slow cooker once you're finished cooking.
  • If you like a bit of crunch in your brownies, then you can try adding some chopped walnuts. Simply mix these in at the same time as all the dry ingredients.
  • All slow cookers cook at different temperatures, so you may find that you need more or less time. I would personally check at the 3-hour mark if you know your slow cooker typically cooks hot.
  • You can make these brownies gluten-free by replacing the plain flour with a gluten-free variety. You might also want to double check the ingredients in the baking powder.
