Ingredients
To make the Easy Plum Crumble Bars, you’ll need:
- 2 cups plums, pitted and diced
- 1 cup all-purpose flour
- 1 cup rolled oats
- 1/2 cup brown sugar
- 1/2 cup granulated sugar
- 1/2 cup unsalted butter, softened
- 1 tsp cinnamon
- 1/2 tsp salt
- 1/4 tsp baking powder
Step-by-Step Instructions
- Preheat the Oven: Start by preheating your oven to 350°F (175°C). This ensures that your Easy Plum Crumble Bars bake evenly.
- Prepare your Baking Dish: Grease an 8-inch square baking dish with a little butter or cooking spray, so the bars don’t stick.
- Make the Crumble Mixture: In a mixing bowl, combine the flour, rolled oats, brown sugar, granulated sugar, cinnamon, salt, and baking powder. Mix well until all dry ingredients are combined.
- Add the Butter: Add the softened unsalted butter to the dry mixture. Using your fingers or a pastry cutter, mix until the mixture resembles coarse crumbs.
- Layer the Plums: Take half of the crumble mixture and press it firmly into the bottom of your greased baking dish. This acts as the base for your Easy Plum Crumble Bars.
- Add the Plums: Spread the diced plums evenly over the pressed crumble base.
- Top with Remaining Crumble: Sprinkle the remaining crumble mixture over the plums, ensuring even coverage.
- Bake: Place the dish in the preheated oven and bake for 30-35 minutes or until the top is golden brown and the plums are bubbling slightly.
- Cool and Serve: Let the bars cool in the pan before cutting into squares. These bars are best served warm but can also be enjoyed at room temperature.
Top Tips for Perfecting Easy Plum Crumble Bars
- Plum Substitutes: If you can’t find plums, you can use peaches or nectarines as a delightful alternative! They’ll bring a slightly different flavor profile but work just as wonderfully.
- Timing: Keep an eye on the crumble towards the end of the baking time. Ovens can vary, and you want to make sure your bars don’t burn.
- Common Mistakes to Avoid: Avoid over-mixing the crumble topping once you add the butter. You want that crumbly texture, not a doughy one. Also, don’t skip the cooling process; it helps the bars hold their shape!
Storing and Reheating Tips
Once these Easy Plum Crumble Bars have cooled, you can store them in an airtight container in the refrigerator for up to one week. If you want to save them for later, they freeze beautifully for up to three months. To reheat, simply place the bars in a preheated oven at 350°F (175°C) for about 10-15 minutes until warmed through. This will help maintain that wonderfully crunchy texture that you fell in love with!
