These slow cooker 3-ingredient salted caramel brownie packets are my laid-back answer to dessert for a crowd when I’m juggling work, kids’ activities, and a spring cookout. My sister actually showed me this trick years ago: instead of baking a whole pan of brownies, you make mini foil-wrapped dessert bombs that stay gooey inside and feel a little bit like unwrapping a present. Everything cooks together in the slow cooker, so you’re not heating up the oven, and you can stack the little foil packets right in the pot. The result is warm, fudgy brownie bites with melty caramel and a hint of salt, all made from pantry-friendly ingredients and almost no effort.
Serve these brownie packets straight from the slow cooker, still wrapped in their foil so everyone can grab one and unwrap it at the table or around the patio. Drizzle a little extra caramel sauce over the tops right before serving for a glossy, sticky finish, and add a light sprinkle of flaky sea salt if you like things extra salty-sweet. They’re perfect with vanilla ice cream or a dollop of whipped cream, but they’re just as good eaten with a spoon right out of the foil. Pair with coffee, cold brew, or a simple glass of milk to balance the richness.
Slow Cooker Salted Caramel Brownie PacketsServings: 8–10 foil packets
Ingredients
1 (18–20 oz) box brownie mix (plus water, oil, and egg if called for on box)
1 cup soft caramel candies or caramel bits, unwrapped
1 teaspoon flaky sea salt or coarse sea salt
Directions
Prepare the slow cooker: Set a large oval or round slow cooker on the counter and clear enough space to stack foil packets inside. Tear off 8–10 pieces of heavy-duty aluminum foil, each about 10–12 inches long, and set them aside. If you don’t have heavy-duty foil, use two layers of regular foil for each packet so they don’t tear.
Mix the brownie batter: In a medium mixing bowl, prepare the boxed brownie mix according to the package directions, using the amount of water, oil, and egg(s) listed on the box. Stir just until the batter is smooth and no dry pockets of mix remain. The batter will be thick.
Portion the batter onto foil: Lay one piece of foil on the counter, shiny side in. Spoon about 1/4 cup of brownie batter into the center of the foil and gently spread it into a small mound, about 3 inches across, leaving plenty of foil around the edges for wrapping. Repeat with the remaining foil pieces and batter until you’ve used up the batter.
Add the caramel and salt: Divide the caramel candies or caramel bits evenly among the brownie mounds, pressing them lightly into the center of the batter so they’re slightly nestled but not completely buried. Sprinkle each mound with a pinch of flaky or coarse sea salt, saving a little salt for finishing, if desired.
Wrap the dessert bombs: Bring the long sides of the foil up and over the brownie mound, then fold them together tightly to seal. Fold in the short sides as well to create a snug little packet, making sure there are no gaps where batter or melted caramel could leak out. The packets should look like small, tightly wrapped foil bricks. Repeat with all portions.
Arrange in the slow cooker: Place a single layer of foil packets in the bottom of the slow cooker, seam side up. If needed, stack additional packets on top, alternating the direction you place them so they fit snugly. It’s okay if they’re slightly on their sides or leaning; they’ll still cook through.
Cook the packets: 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. The exact time will depend on your slow cooker and the size of your packets. The brownies are done when they feel set and slightly firm when you gently press the top of a packet with a spoon, but they should still be soft and gooey inside.
Finish with caramel drizzle: Once done, turn the slow cooker to WARM. Carefully open one test packet (watch out for hot steam) to check for doneness and gooeyness. If you like, drizzle a little extra caramel sauce (melt a few extra caramels with a splash of water, or use bottled caramel) over the tops of the closed foil packets right in the slow cooker, then sprinkle with a bit more flaky salt. Close the lid and let them sit on WARM for 5–10 minutes so the caramel on top gets glossy.
Serve: Use tongs to lift the warm foil packets out of the slow cooker and onto a platter. Keep them wrapped so everyone can open their own little dessert bomb. Serve with spoons for scooping out the gooey salted caramel brownie center, and add ice cream or whipped cream on the side if you have a few extra minutes.
Variations & Tips
For extra chocolate, tuck a few chocolate chips or chunks into the center of each brownie mound along with the caramel (this technically adds an ingredient, but you can treat it as optional). If you prefer less salt, cut the sea salt down to 1/2 teaspoon and skip the finishing sprinkle, or use a milder kosher salt instead of flaky sea salt. To make these more kid-friendly, leave off the salt entirely and just serve them as caramel brownie packets. For a nuttier twist, stir a handful of chopped pecans or walnuts into the brownie batter before portioning (again, an optional add-on). If you don’t have boxed brownie mix, you can use any thick brownie batter recipe you like as long as it yields about the same amount as a standard box. To prep ahead, assemble the foil packets up to 24 hours in advance and refrigerate them on a baking sheet; when you’re ready, transfer the cold packets straight into the slow cooker and add about 15–20 minutes to the cooking time. Clean-up tip: line the bottom of your slow cooker with a sheet of parchment or an extra layer of foil before adding the packets to catch any caramel drips.
