2 tablespoons butter
2/3 cup heavy whipping cream
1/2 cup corn syrup
1/4 cup packed brown sugar
1/4 cup cocoa powder
1/4 teaspoon salt
3/4 cups semi-sweet chocolate chips
1/2 teaspoon vanilla extract
1 box fudge brownie mix
2/3 cup vegetable oil
1/4 cup water
2 eggs
In a small saucepan set over medium heat, combine the butter, cream, cocoa and salt. Bring to a simmer, then let it simmer for 3 to 5 minutes.
Remove sauce from heat and stir in the chocolate chips until melted.
Add vanilla extract to the sauce and stir. Allow sauce to cool slightly.
Line a 6-quart slow cooker with a slow cooker liner or aluminum foil. Spray liberally with non-stick cooking spray.
In a large bowl combine the brownie mix, vegetable oil, 1/4 cup water and eggs. Mix well, then pour batter into the prepared slow cooker.
Pour the hot fudge sauce over the brownies and do not stir.
Place the lid on the slow cooker, then cook for 2 1/2 to 3 hours on high until the edges are set and the center is still slightly gooey.
Turn slow cooker off, remove lid and allow brownies to cool slightly before scooping out and serving.
