This slow cooker 5-ingredient shoofly cake is my cozy, shortcut take on the old-fashioned Amish and Pennsylvania Dutch classic. Instead of fussing with a pie crust and oven, everything goes right into the slow cooker in simple layers. A thick, dark molasses bottom slowly bubbles away until it turns into a rich, gooey syrup that melts in your mouth, while a buttery cake mix bakes up into a crumbly golden streusel on top. It’s the kind of church-basement dessert a friend shares with you on a recipe card, and once you taste it warm with that syrup pooling around the edges, you’ll see why it’s such a keeper for potlucks and family nights.
Serve this shoofly cake warm, scooped straight from the slow cooker or cut into squares once it’s set a bit. Spoon some of the dark syrup from the bottom over each serving so it puddles around the cake on the plate. A scoop of vanilla ice cream or a dollop of whipped cream is lovely on top, and a hot cup of coffee, tea, or cold milk balances the sweetness nicely. It’s rich enough to stand alone, so you don’t need extra sides—just a simple, homey dessert to pass around the table.
Slow Cooker 5-Ingredient Shoofly CakeServings: 8-10
Ingredients
1 cup unsulfured molasses
1 cup hot water
1 box (15.25 ounces) yellow cake mix
1/2 cup (1 stick) unsalted butter, melted
1/2 cup packed light brown sugar
Directions
Lightly grease the inside of a 4- to 6-quart slow cooker with butter or nonstick spray to help the cake release and make cleanup easier.
In a medium bowl or large measuring cup, whisk together the molasses and hot water until smooth and well combined. The mixture will be thin and very dark.
Pour the molasses mixture into the bottom of the prepared slow cooker, tilting the crock gently if needed so it covers the entire bottom in an even layer. This will become the gooey, syrupy base.
In a separate medium bowl, add the dry yellow cake mix and the packed brown sugar. Use a fork or your fingers to blend them together until the brown sugar is evenly distributed and there are no big clumps.
Sprinkle the dry cake mix and brown sugar mixture evenly over the molasses layer in the slow cooker. Do not stir; you want distinct layers so the molasses can bubble up underneath while the top becomes crumbly and golden.
Slowly drizzle the melted butter evenly over the surface of the dry cake mix layer, trying to cover as much of the top as possible. Some dry spots are okay; they will turn into a streusel-like crumb topping as it cooks.
Cover the slow cooker with its lid. Cook on LOW for 2.5 to 3.5 hours, or until the top is set, lightly golden, and mostly dry to the touch, while the bottom is still soft and bubbling. The center may jiggle slightly from the molten molasses layer underneath, which is what you want.
Once cooked, turn off the slow cooker and let the cake rest, covered, for about 15 to 20 minutes. This helps the layers settle while still keeping the bottom warm and gooey.
To serve, spoon or lift portions of cake out of the slow cooker, making sure to scoop down to the bottom so you get plenty of the dark, syrupy molasses along with the crumbly golden topping. Serve warm on white plates with the rich syrup pooling around the edges.
Variations & Tips
For a slightly less intense molasses flavor, you can use half molasses and half dark corn syrup, keeping the total liquid at 1 cup plus 1 cup hot water. If your family prefers a bit of spice, whisk 1 to 2 teaspoons of pumpkin pie spice or ground cinnamon into the dry cake mix and brown sugar before layering. For a deeper, more old-fashioned flavor, use a spice cake mix instead of yellow cake mix, still keeping the total ingredient count at five. To make individual servings for picky eaters, you can line the bottom of the slow cooker with parchment and later cut the cake into neat squares—kids often like seeing their own little piece with extra syrup spooned on top. If your slow cooker runs hot, start checking for doneness at the 2-hour mark so the top doesn’t overbrown; you can lay a piece of paper towel under the lid to catch excess condensation and keep the streusel topping from getting soggy. Leftovers reheat well in the microwave for 15–20 seconds per piece, and a splash of cream or a spoonful of yogurt on top can help tone down the sweetness for breakfast-style leftovers.
