My sister brought this to our Memorial Day cookout and everyone thought she spent hours on it. The secret is embarrassingly simple

This slow cooker 3-ingredient strawberry lemonade cake is exactly the kind of dessert that makes people think you fussed for hours, when really you just stirred a few things together and walked away. My sister brought a version of this to our Memorial Day cookout one year, and everyone hovered over the slow cooker, scooping out warm, pink-tinted cake with ribbons of bright lemon running through it. It tastes like a mash-up of strawberry shortcake and lemon bars, and because it bakes right in the slow cooker, it stays incredibly moist and tender—perfect for busy days, hot weather, or whenever you want an easy treat that still feels special.

Serve this cake warm, straight from the slow cooker, spooned into bowls. It’s lovely on its own, but a dollop of whipped cream or a scoop of vanilla ice cream really leans into that strawberries-and-cream vibe. For a lighter touch, add fresh sliced strawberries or raspberries on top. It pairs nicely with grilled foods at a cookout, simple burgers and hot dogs, or even just coffee or iced tea on a quiet evening. If you’re feeding kids, let them sprinkle on a few mini marshmallows or colored sprinkles right before serving for a little extra fun.

Servings: 8-10

1 box (15.25 to 16.25 ounces) strawberry cake mix

Lightly grease the inside of a 5- to 6-quart slow cooker with nonstick spray or a thin layer of butter to help keep the cake from sticking.

In a large mixing bowl, add the dry strawberry cake mix and the entire can of strawberry pie filling. Stir together with a sturdy spoon or spatula until no dry pockets of mix remain. The batter will be thick and very chunky from the strawberries.

Spoon the strawberry batter into the prepared slow cooker and spread it into an even layer, making sure it reaches the edges for even cooking.

Open the jar of lemon curd and give it a quick stir to loosen it. Dollop the lemon curd all over the top of the strawberry batter in large spoonfuls.

Use a butter knife or the tip of a spatula to gently swirl the lemon curd into the batter. Don’t overmix—you want visible ribbons and pockets of bright yellow lemon running through the pink batter for that pretty marbled look and bursts of lemon flavor.

Cover the slow cooker with its lid. Cook on HIGH for 2 to 2 1/2 hours, or on LOW for 3 1/2 to 4 hours, until the cake is set in the center. The edges will pull slightly away from the sides, and a toothpick inserted into the center should come out mostly clean, with just a few moist crumbs (avoid a lemon-curd pocket when testing).

Once done, turn off the slow cooker and let the cake sit, covered, for about 10 to 15 minutes to set up slightly. This helps it hold together better when scooping.

Serve the cake warm, scooping it straight from the slow cooker into bowls. Store any leftovers, cooled to room temperature, in an airtight container in the refrigerator for up to 3 days. Reheat gently in the microwave before serving.

For a lighter lemon flavor, use only 3/4 of the jar of lemon curd and save the rest to drizzle over individual servings. If your family loves extra lemon, you can gently warm a bit more lemon curd in the microwave and spoon it over the warm cake like a sauce. For picky eaters who aren’t big on obvious fruit pieces, you can briefly pulse the strawberry pie filling in a food processor or mash it with a fork before mixing it with the cake mix to break down larger chunks. If you prefer a slightly less sweet dessert, look for a “reduced sugar” or “no sugar added” strawberry pie filling. For a fun twist, try raspberry pie filling instead of strawberry for a raspberry lemonade version, or use a lemon cake mix with the strawberry pie filling for more of a lemon-first flavor. To dress it up for guests, top each serving with whipped cream and fresh sliced strawberries or a sprinkle of finely grated lemon zest. Food safety tips: Because this cake is very moist and contains fruit and eggs from the mix, don’t leave it sitting out at room temperature for more than 2 hours—refrigerate leftovers promptly. Make sure your slow cooker is in good working order and heats properly; if it’s older and tends to run hot, start checking the cake about 15 minutes early to avoid overcooking or scorching around the edges. Always allow the cake to cool slightly before covering tightly for storage so excess steam doesn’t create too much condensation, which can encourage spoilage.
