Ingredients You’ll Need
- 1 ¾ cup all-purpose flour: This forms the base of our crust. Choose a high-quality flour for the best results; you can substitute it with whole wheat flour for added nutrition.
- â…” cup sugar: Used to sweeten the base dough. For a healthier alternative, try coconut sugar or a sugar substitute.
- ½ tsp baking powder: This gives the bars a light texture. Make sure it’s fresh for the best rise.
- ¼ tsp salt: A small amount enhances the flavors; do not skip it!
- ½ cup butter, cold: The key to a flaky crust. Cut it into small pieces and keep it in the fridge until ready to use.
- 1 egg, whisked: This binds the ingredients together. You can replace it with a flax egg for a vegan option.
- 2 tbsp milk: Helps bring the dough together. Dairy-free milk works just as well.
- 4 plums, diced small: The star of our show! Choose ripe, sweet plums for maximum flavor.
- ¼ cup sugar: Sweetens the plum filling. Adjust according to your taste preference.
- 2 tbsp all-purpose flour: Thickens the plum filling and prevents it from getting too runny.
- ½ tsp vanilla extract: Adds depth of flavor to the bars; feel free to use almond extract for a different twist.
How to Make Plum Bars
- Prepare the Oven and Pan: Preheat your oven to 400°F. Line an 8×8 baking dish with parchment paper, letting it hang over the edges for easy removal later.
- Make the Crust Mixture: In a large mixing bowl, combine the 1 ¾ cup all-purpose flour, ⅔ cup sugar, ½ tsp baking powder, and ¼ tsp salt. Grate the cold butter into the mixture using a cheese grater, incorporating it with your hands until it resembles small pebbles.
- Combine Wet Ingredients: Add the whisked egg and 2 tbsp milk to the flour mixture and stir until everything is just combined.
- Prepare the Plum Filling: In a separate bowl, combine the diced plums, ¼ cup sugar, 2 tbsp all-purpose flour, and ½ tsp vanilla extract. Mix gently to coat the plums evenly.
- Assemble the Bars: Press about â…” of the crust mixture into the lined baking pan. Evenly spread the plum mixture on top, ensuring it covers the crust. Crumble the remaining crust mixture over the plums, distributing it evenly.
- Bake: Place the pan in the preheated oven and bake for 30-32 minutes, or until the edges are golden brown, and the plum filling is bubbling.
- Cool and Enjoy: Once done, let the bars cool at room temperature. Then, slice them into squares and enjoy your delectable plum bars!
Storing & Reheating
To store your delicious plum bars, keep them at room temperature for up to 2 days, covered with foil or stored in an airtight container. For longer storage, refrigerate them for up to a week, ensuring you use a suitable container. You can also freeze the bars for up to 3 months—just cut them into squares, wrap each piece individually, and store them in a freezer-safe bag. To reheat, bake in a preheated oven at 350°F for about 5-7 minutes until warm. Note that freezing may alter the texture slightly, but refreshing them in the oven can revive their lovely flavor.
Chef’s Helpful Tips
- Avoid overmixing the crust to keep it light and flaky.
- Feel free to swap out the plums for other fruits like peaches or cherries based on what’s in season or your personal preference.
- Make sure your butter is cold; this is crucial for achieving that perfect buttery texture!
- If the filling looks runny, it may benefit from baking an extra couple of minutes.
- You can prepare the crust ahead of time; just keep it chilled until you’re ready to bake.
Plum Bars are not just a sweet treat; they allow you to experiment with flavors and textures that evoke nostalgia. Each slice bursts with juicy plum flavor alongside the buttery crust, reminding you of warm summer days. So, why not take some time to get your hands floury and create something special? Enjoy every single bite!
