How To Make Slow Cooker Brownies
In a large bowl, whisk the melted butter and sugar together until well-combined. Add the eggs and vanilla extract and whisk in until well-combined.
Add the flour, cocoa powder, baking soda, and salt. Whisk in just until incorporated.
Stir in the chocolate chunks just until incorporated. Don't overmix.

Cook for 2-3 hours or until the edges are set and the center is fudgy.
How To Serve Brownies
These brownies are best served warm. They can be served as-is or topped with vanilla ice cream or whipped cream.
Tips For Making Slow Cooker Brownies
- The thin cotton towel helps to absorb moisture as it cooks. Just be sure that the cotton towel isn't too thick.
- I recommend mixing the batter by hand to avoid overworking the batter.
- If you have questions about making or baking brownies, check out my post on how to make brownies.
- The center of the brownies will still look gooey on top. The brownies should look done and shiny around the edges when cooked.
- If your slow cooker has a hot spot in it, line it with a foil collar before cooking.
