Step-by-step directions
-
Prep the slow cooker. Lightly grease the inside of the slow cooker with nonstick spray or a little softened butter. This helps prevent sticking and makes serving easier.
-
Combine the batter. In a large bowl, add the boxed brownie mix, 2 eggs, melted butter, and 2 cups milk. Whisk or stir until the batter is smooth and no dry streaks remain. The batter will be thinner than a typical oven brownie batter — that’s normal for the pudding texture.
-
Pour into slow cooker. Pour the batter into the prepared slow cooker and smooth the top gently with a spatula.
-
Cover and cook. Place the lid on and cook on LOW for 3 to 4 hours. Start checking at 3 hours: the edges should be set and the center slightly gooey and pudding-like. If you prefer a firmer set, add 15–30 minutes.
-
If using HIGH: cook about 1.5–2 hours, but check at 90 minutes. HIGH can finish faster but may cook less evenly.
-
-
Cool slightly & serve. Turn off the slow cooker and let the brownie pudding cool 15 minutes with the lid off. This helps it set a little and makes scooping cleaner. Serve warm.
Texture expectations
This dessert is a pudding-style brownie: edges set and fudgy, center soft and spoonable. If you want a cakier finish, reduce the milk slightly (try 1¾ cups) or cook a bit longer.
Variations & add-ins
-
Vanilla or espresso: Add 1 tsp vanilla extract or 1 tbsp espresso powder for depth.
-
Mix-ins: Stir in 1/2–1 cup chocolate chips, chopped nuts, or toffee bits before pouring.
-
Peanut butter swirl: Dollop spoonfuls of peanut butter on top after pouring batter and swirl with a knife.
-
Salted caramel: Drizzle caramel and a pinch of flaky sea salt before serving.
-
Lighter version: Use low-fat milk and a reduced-fat butter substitute (results slightly less rich).
Serving suggestions
-
Scoop warm into bowls and top with vanilla ice cream for a perfect contrast.
-
Add whipped cream, hot fudge, or chopped toasted nuts.
-
Dust with powdered sugar or cocoa for a pretty finish.
Make-ahead, storage & reheating
-
Make-ahead: Assemble batter and refrigerate in a covered bowl up to 8 hours before cooking (stir again before pouring). Do not leave batter at room temp for long.
-
Refrigerate: Store cooled leftovers in an airtight container for 3–4 days.
-
Freeze: Portion into freezer-safe containers up to 2 months. Thaw overnight in the fridge and reheat.
-
Reheat: Microwave single portions 20–45 seconds (depending on microwave) or warm in a covered dish in a 325°F (160°C) oven until heated through.
Troubleshooting
-
Too runny in center? Cook an extra 20–30 minutes on LOW and check again. Different slow cooker models and sizes affect time.
-
Edges overcooked/dry? Your slow cooker may run hot or cook unevenly — try checking earlier next time or reduce cook time by 10–20 minutes. A larger slow cooker will cook faster because the batter spreads thinner.
-
Top crust formed but center raw? Finish with the lid off for 10–15 minutes to allow gentle evaporation and setting, or reduce initial lid-time next round.
