This recipe shows you how you can make slow cooker brownies from scratch. They come out to be amazing and gooey and go really well with some vanilla ice cream.

Slow Cooker Brownies

With these brownies, you can add some extra chocolate chips if you want some extra gooey bits of chocolate. If you really want to be creative, you can add white chocolate chips so you end up with a double chocolate brownie that you would please any chocolate lover.

Like most desserts you cook in the slow cooker this will only need a few hours to have it ready for eating. You will need to keep this in mind when you’re timing what time you want to eat.

The chocolate lava cake for the slow cooker is also perfect if you’re a huge fan of rich chocolate desserts. The best thing is that you can easily just scoop straight out of the slow cooker and on to your plate.

This brownie can be stored in the fridge and simply reheated whenever you need it. It should last about a week (maybe longer) if stored correctly. If it smells or looks off, then just discard it.

Cooking 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 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 will personally check at the 3-hour mark if you know your slow cooker typically cooks hot.
