Fourth of July Classic: Only 4 ingredients. I make it when I want a crowd-pleasing dessert handled hours ahead with absolutely zero fuss.

This 4-ingredient slow cooker vintage apple dapple cake is my secret weapon for Fourth of July and any time I need a crowd-pleasing dessert done hours ahead with absolutely zero fuss. It’s inspired by those old church cookbook “dump cakes” and classic apple dapple cakes from the 60s and 70s, but streamlined for a busy schedule and a slow cooker. You literally stir, dump, and walk away. A few hours later you’ve got a bubbling, caramelized, apple-studded cake with a golden, syrupy crust that looks like you’ve been in the kitchen all day, even if you’ve been out at the parade or chasing kids through the sprinkler.

Serve this warm right out of the slow cooker, scooped into bowls like a cobbler. I love it with a big scoop of vanilla ice cream or a dollop of whipped cream so it melts into all the caramelized apple-y pockets. For a Fourth of July spread, park the slow cooker on the dessert table, set out bowls, spoons, and a tub of ice cream, and let guests help themselves. Coffee or hot tea is perfect if you’re serving it later in the evening, and if you want to lean into the holiday, sprinkle the top of each bowl with red and blue sprinkles over the ice cream.

Servings: 8-10

2 (21-ounce) cans apple pie filling, diced in the can or bowl

Lightly grease the inside of a 5- to 6-quart slow cooker with nonstick spray or a thin layer of butter to help prevent sticking and make cleanup easier.

Open both cans of apple pie filling and roughly dice the apples right in the can or in a bowl using a butter knife or kitchen scissors so you have bite-sized pieces. This helps the apples spread evenly through the cake.

Pour the diced apple pie filling into the bottom of the slow cooker and spread it into an even layer so the whole base is covered.

Sprinkle the dry yellow cake mix evenly over the apples, covering them completely. Do not stir; you want a dry layer of cake mix sitting on top of the fruit.

In a small bowl, stir the brown sugar with the melted butter until it forms a thick, glossy, pourable mixture. It will look like a loose caramel sauce.

Slowly drizzle the butter–brown sugar mixture all over the surface of the dry cake mix, trying to moisten as much of the top as possible. It’s okay if a few dry spots remain; the apple juices will rise and help hydrate those as it cooks.

Cover the slow cooker with its lid. Cook on HIGH for 2.5 to 3 hours or on LOW for 4 to 4.5 hours, until the top looks set, the edges are deep golden and caramelized, and the fruit is bubbling up around the sides. Avoid lifting the lid in the first 2 hours so you don’t lose heat and add extra time.

Once cooked, turn off the heat and let the cake sit, covered, for 15 to 20 minutes. This rest time helps the syrup thicken and the cake layer firm up a bit while still staying gooey and spoonable.

Spoon the warm apple dapple cake straight from the slow cooker into bowls. Serve as-is or top with vanilla ice cream or whipped cream. Switch the slow cooker to WARM to hold it for serving for up to 1.5 to 2 hours, checking occasionally so it doesn’t over-brown around the edges.

You can easily tweak this to fit your family and what you have on hand while still keeping it low-fuss. For a nutty “vintage potluck” vibe, sprinkle 1/2 to 3/4 cup chopped pecans or walnuts over the dry cake mix before you drizzle on the butter–brown sugar mixture; this technically adds a fifth ingredient but doesn’t complicate the process. If you want a little spice without buying anything special, you can use a spice cake mix instead of yellow cake mix, or just add 1 to 2 teaspoons ground cinnamon to the dry cake mix before sprinkling it over the apples (again, that’s an optional extra). For a slightly lighter version, you can use 3/4 cup melted butter instead of 1 cup; the top will be a bit less rich but still caramelized. If you prefer more noticeable apple chunks, dice only half the apples and leave the rest in larger pieces. To make this more portable for a cookout, line the slow cooker insert with a wide sheet of parchment that comes up the sides before greasing; once cooled slightly, you can lift the whole cake out and cut it into squares. Food safety tips: Always cook this on HIGH or LOW as directed; don’t use the WARM setting to cook from start to finish, as it may not bring the dessert to a safe temperature quickly enough. Leftovers should be cooled, then transferred to an airtight container and refrigerated within 2 hours of cooking. Reheat individual portions in the microwave until steaming hot (165°F in the center if you’re checking). Avoid leaving the cake sitting out at room temperature for more than 2 hours, especially at summer gatherings when it’s warm outside. If you’re serving from the slow cooker for an extended time, keep it on WARM and keep the lid partially on to maintain heat while still allowing easy access for scooping.
