Why it works: Chocolate and syrup are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 1,239 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Hot Fudge Brownies
Ingredients
Directions
Prepare
Open the Slow Cooker Liner and place it inside a 5-6 1/2-quart slow cooker bowl.
Fit the liner snugly against the bottom and sides of the bowl; pull the top of the liner over the rim of the bowl.
Prepare the brownie mix according to the package directions for cake-like brownies.
Spread the batter evenly in the lined slow cooker bowl.
Mix the chocolate syrup and hot water; pour the syrup mixture evenly over the brownie batter.
Cook
Place the lid on the slow cooker.
Cook on high for 2 ½–3 hours or until the brownie edges are set.
Carefully remove the lid to allow steam to escape; the center may appear moist but a wooden pick inserted near the center should come out clean.
Let stand 30 minutes, uncovered, for the center to set completely.
Serve and clean up
Serve the brownies with a plastic or wooden spoon directly from the slow cooker; do not lift or transport the liner with food inside.
Cool the slow cooker completely, then remove and toss the liner.

What each ingredient does
- Brownie mix
- Provides the batter that sets into the brownie structure and chocolate flavor.
- Chocolate syrup
- Adds sweetness, chocolate flavor and moisture to the top layer of the brownies.
- Hot water
- Helps the chocolate syrup loosen and spread into a moist sauce layer.
The step that matters
Judging doneness by edges and a wooden pick. The center can look moist yet still be underbaked; checking that edges are set and a pick near the center comes out clean helps avoid a gummy middle. Letting it stand uncovered lets the center finish setting as steam leaves.
