July Fireworks Bowl: Exactly 4 ingredients. I throw this together when I want the slow cooker to do the heavy lifting while we watch the parade.

This little July Fireworks Bowl is my lazy-day answer to a festive dessert when the slow cooker can do the work while we sit on the porch and listen for the first crackle of the parade fireworks. It’s only four ingredients, but when they bubble together you get a deep crimson and indigo, almost like the sky just after sunset, with a pale golden crust on top. It reminds me of the old Midwestern church potlucks where somebody always brought a hot fruit cobbler that looked a little messy but tasted like pure summer. This version skips the oven, keeps the house cool, and lets you set it and forget it until it turns into a glistening, spoonable bake that feels right at home on Independence Day.

Serve this warm right out of the slow cooker, spooned into bowls so you can see those crimson and indigo juices peeking through the toasted top. A scoop of vanilla ice cream or a dollop of lightly sweetened whipped cream melts down into the fruit and soft cake, making it extra indulgent. It pairs nicely with simple picnic fare—grilled hot dogs, burgers, or fried chicken—and a crisp green salad. I like to set the slow cooker on the buffet with a ladle and stack of bowls, so folks can help themselves between parade watching and waiting for the evening fireworks.

Servings: 6-8

1 (21-ounce) can cherry pie filling

Lightly grease the inside of a 4- to 6-quart slow cooker with butter or nonstick spray so the edges of the crust toast instead of sticking.

Spoon the cherry pie filling into the bottom of the slow cooker and spread it into an even layer. This will give you that bright crimson base.

Spoon the blueberry pie filling over the cherry layer in dollops, gently swirling with the back of the spoon just enough so you can still see patches of deep indigo and red. Don’t overmix; you want a marbled look when it bubbles.

Sprinkle the dry yellow cake mix evenly over the top of the fruit, covering it completely. Do not stir; the dry mix will form the pale golden crust as it cooks.

Slowly drizzle the melted butter over the dry cake mix, trying to moisten as much of the surface as you can. It’s fine if a few dry spots remain; they’ll toast up nicely into a light, crumbly topping.

Cover the slow cooker with the lid. Cook on HIGH for 2 1/2 to 3 hours, or on LOW for 4 to 5 hours, until the fruit is bubbling around the edges in glossy crimson and indigo pockets and the top is mostly set with pale golden, lightly toasted spots.

Once cooked, turn off the heat and let the dessert sit, covered, for about 15 minutes. This rest helps the juices thicken slightly while still staying soft and spoonable.

Spoon the warm bake into bowls, making sure each serving gets some of the bubbling fruit and the toasted crust from the top. Serve as-is or with ice cream or whipped cream.

For a slightly tarter, more old-fashioned flavor, you can swap the cherry pie filling for canned tart cherries in light syrup; just drain most of the liquid and stir in 1/2 cup sugar before layering with the blueberries. A white or French vanilla cake mix can stand in for yellow if that’s what you keep in your pantry. If you’d like a stronger berry note, use all blueberry filling and add a handful (about 1 cup) of fresh or frozen blueberries on top of the canned filling before adding the cake mix. For a bit of crunch, sprinkle 1/2 cup chopped pecans or walnuts over the cake mix before drizzling on the butter, which is very much in the spirit of Midwestern potluck desserts. To keep the red and blue colors more distinct, avoid stirring the fruit once it’s layered; just let it marble naturally as it bubbles. Food safety tips: Always start with clean hands, utensils, and a clean slow cooker insert. Keep the pie fillings refrigerated until you’re ready to assemble. Do not leave the finished dessert sitting on WARM or at room temperature for more than 2 hours; after that, cool leftovers quickly, transfer to shallow containers, and refrigerate. Reheat leftovers thoroughly until steaming before serving. If you’re using a very old slow cooker that tends to run cool, stick with the HIGH setting and allow extra time, making sure the center is hot and bubbling before you serve.
