This recipe for slow-cooker Chocolate Pudding Cake may sound, well, like a recipe for disaster—combine dry ingredients with wet, scrape into the slow cooker, sprinkle with sugar and cocoa powder, and then pour boiling water over the whole thing—but trust us, all will be well and delicious. The cocoa and sugar on top of the batter bubble as they cook to form a pudding-style chocolate sauce on the bottom, while a chewy, brownie-like cake rises to the top. The batter is a simple mixture of pantry staples—flour, sugar, cocoa, baking powder, and salt combined with milk, melted butter, egg yolk, and vanilla. We folded in a handful of semisweet chocolate chips to add another layer of flavor and ensure plenty of gooey pockets in the baked cake.
Serves 6 to 8
Cooking time: 1 to 2 hours on high
Slow cooker size: 4 to 7 quarts
You will need an oval slow cooker for this recipe. For an accurate measurement of boiling water, bring a full kettle of water to a boil and then measure out the desired amount.
1 cup (5 ounces) all-purpose flour
1 cup (7 ounces) sugar
½ cup (1½ ounces) unsweetened cocoa powder
2 teaspoons baking powder
¼ teaspoon salt
½ cup whole milk
4 tablespoons unsalted butter, melted and cooled
1 large egg yolk, room temperature
2 teaspoons vanilla extract
½ cup (3 ounces) semisweet chocolate chips
1 cup boiling water
1. Line slow cooker with aluminum foil collar and lightly coat with vegetable oil spray. Whisk flour, ½ cup sugar, ¼ cup cocoa, baking powder, and salt together in large bowl. In separate bowl, whisk together milk, melted butter, egg yolk, and vanilla. Stir milk mixture into flour mixture until just combined. Fold in chocolate chips (batter will be stiff).
2. Scrape batter into prepared slow cooker and spread to edges. Combine remaining ½ cup sugar and remaining ¼ cup cocoa in clean bowl and sprinkle evenly over top. Slowly pour boiling water evenly over top. Do not stir. Cover and cook until cake is puffed, top is lightly set, and center is gooey when pierced with toothpick, 1 to 2 hours on high.
3. Discard foil collar. Turn off slow cooker and let cake sit, covered, for 10 minutes before serving.
