Spray a 6-7 quart slow cooker with nonstick cooking spray.

Prepare the Pillsbury™ brownie mix as directed on the back of the box.

Pour brownie mixture into prepared slow cooker.

Whisk pudding mix and milk in a bowl until smooth.

Pour pudding over the brownie mix in the crock pot.

Cook on high power 2-3 hours.  Start checking after 2 hours to see if the edges are dry.  The cake is lava cake so a portion will remain gooey.

Serve warm topped with ice cream.
