When I need a hands-off dessert for a busy holiday weekend, this slow cooker oatmeal crisp-style treat is exactly the kind of recipe I reach for. It uses pantry-friendly raw dry oatmeal flakes and just four other ingredients to create a warm, spoonable dessert with cozy flavor and almost no effort. It feels a little like the easiest fruit crisp ever, which makes it perfect for Labor Day gatherings when the oven is already busy and I still want something homemade on the table.
Serve this warm in bowls on its own, or make it feel extra special with a scoop of vanilla ice cream or a dollop of whipped cream. It also pairs well with grilled cookout favorites because the sweet, cinnamon-apple flavor is a nice contrast to savory burgers, hot dogs, or barbecue, and a cup of coffee alongside leftovers the next day is honestly hard to beat.
5-Ingredient Slow Cooker Apple Oat DessertServings: 6
3 cups raw dry oatmeal flakes
1 can (21 ounces) apple pie filling
1/2 cup brown sugar
1 teaspoon ground cinnamon
1/2 cup unsalted butter, melted
1. Lightly grease the inside of the slow cooker. Add the raw dry oatmeal flakes to the bottom, then spoon the apple pie filling over the oats.
2. Sprinkle the brown sugar and cinnamon evenly over the top, then drizzle the melted butter all over the mixture.
3. Cover and cook on low for 2 1/2 to 3 hours, until the apples are bubbly and the oats are tender around the edges.
4. Turn off the slow cooker and let the dessert rest for 10 to 15 minutes to thicken slightly before serving.
5. Spoon into bowls and serve warm.
Variations & TipsTry a pear version: Swap the apple pie filling for pear pie filling if you can find it. The texture stays soft and cozy, but the flavor feels a little different and perfect for late summer going into fall.
For a richer topping: Add a scoop of vanilla ice cream or a spoonful of whipped cream right before serving. Since this dessert is simple, a creamy topping makes it feel much more finished for guests.
Watch the cooking time: Slow cookers can run a little differently, so start checking at the 2 1/2-hour mark. You want the fruit hot and bubbly and the oats softened, but not dried out.
Make cleanup easier: A light coating of cooking spray or butter inside the crock helps a lot. This is one of those small steps I never skip on a busy workday because it saves time later.
Use old-fashioned oats: Raw dry old-fashioned oatmeal flakes work best here for texture. Quick oats can turn too soft, and steel-cut oats need a different amount of liquid and a longer cook time.
