I have a healthy collection of slow cooker recipes on my blog. I even have a slow cooker recipe sharing group on Facebook. What I didn’t have was a recipe for a slow cooker dessert (except applesauce – but I’m not sure that counts). But by publishing this recipe for Slow Cooker Peanut Butter Brownies I do now have my first official sweet slow cooker dessert.

Slow Cooker Peanut Butter Brownie

I’ve baked a lot of brownies in my day. And I’m fond of adding Reese’s peanut butter cups to my brownies. They make cute little hand-held desserts that hardly anyone can resist.

Watch how to make Slow Cooker Peanut Butter Brownies:

But putting those ingredients in my slow cooker transforms this peanut butter filled brownie into a warm and gooey, hot fudge cake like experience. It’s so quick to throw together too. Just let the slow cooker do its thing and then you can dig into a peanut butter and chocolate lovers dream of a dessert.
