Ingredients
| Ingredient | Amount |
|---|---|
| Oatmeal cookie mix | 1 (17–18-ounce) pouch |
| Unsalted butter, melted | ½ cup (1 stick) |
| Raspberry preserves | 1 to 1¼ cups |
Instructions
Step 1: Prepare the Baking Dish
Preheat the oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with butter or nonstick cooking spray.
Step 2: Make the Crumble Mixture
In a medium bowl, combine the oatmeal cookie mix with the melted butter. Stir until the mixture is evenly moistened and crumbly.
Step 3: Form the Crust
Press about two-thirds of the crumb mixture firmly into the bottom of the prepared baking dish, creating an even layer.
Step 4: Add the Filling
Spread the raspberry preserves evenly over the crust, leaving a small border around the edges if desired to help prevent sticking.
Step 5: Add the Topping
Sprinkle the remaining crumb mixture evenly over the raspberry layer. Leave the topping loose to create a classic crumb texture as it bakes.
Step 6: Bake
Bake for 22–28 minutes, or until the topping is lightly golden and the raspberry filling is bubbling around the edges.
Step 7: Cool Completely
Place the baking dish on a wire rack and allow the bars to cool completely for at least 1 hour before cutting.
Tip: Letting the bars cool completely helps the raspberry filling set, making them much easier to slice and serve.
Step 8: Slice and Enjoy
Cut into 12–16 squares and carefully remove each bar with a spatula. Serve at room temperature and enjoy.
