Ingredients for Nectarine Crumble Bars
For the crust and crumble topping:
• All-purpose flour: Provides the base and structure of the bars.
• Brown sugar: Adds a rich, molasses-like sweetness to the crust.
• Granulated sugar: Balances the richness of the brown sugar.
• Baking powder: Helps the crumble rise slightly for a light texture.
• Cinnamon: Adds warmth and enhances the nectarine filling’s flavors.
• Nutmeg: Complements the cinnamon with a subtle, nutty taste.
• Salt: Balances the sweetness of the sugars.
• Unsalted butter: The key to achieving a buttery, flaky crust and crumble topping.
• Egg: Binds the crust and crumble together, creating a cohesive mixture.
For the nectarine filling:
• Sliced nectarines: Fresh nectarines provide a juicy and vibrant filling.
• Granulated sugar: Sweetens the filling without overpowering the fruit’s natural taste.
• Cinnamon: Enhances the flavor of the nectarines with a touch of spice.
• Cornstarch: Thickens the filling, preventing it from becoming too runny.
• Lemon juice: Adds a zesty brightness to balance the sweetness of the fruit.
• Vanilla extract: Elevates the overall flavor of the filling with a rich aroma.
Alternative Ingredient Suggestions for Nectarine Crumble Bars
If you’re looking to modify the recipe based on dietary preferences or availability, here are some helpful swaps:
• Gluten-free flour: Swap the all-purpose flour for a gluten-free flour blend to make these bars gluten-free.
• Coconut sugar: For a lower glycemic option, use coconut sugar in place of the brown and granulated sugars.
• Vegan butter: Substitute unsalted butter with vegan butter for a dairy-free version.
• Peaches: If nectarines aren’t in season, feel free to swap them for peaches, which will provide a similar texture and flavor.
Step-by-Step Instructions to Make Nectarine Crumble Bars
- Preheat the oven to 350°F (175°C). Line a 9×13-inch baking dish with aluminum foil and lightly spray with cooking spray to prevent sticking.
- In a large food processor, combine the all-purpose flour, brown sugar, granulated sugar, baking powder, cinnamon, nutmeg, and salt. Pulse until all ingredients are well combined.
- Add the cold, unsalted butter into the food processor and pulse until the mixture becomes crumbly.
- Add the whisked egg and pulse again until the dough starts to come together. If the dough doesn’t form easily in the processor, transfer it to a bowl and mix by hand with a spatula.
- Press a little more than half of the dough mixture into the bottom of the prepared baking dish to form the crust. Bake the crust in the preheated oven for 15 minutes.
- While the crust is baking, prepare the nectarine filling. In a large bowl, combine the sliced nectarines, sugar, and cinnamon.
- In a separate small bowl, whisk together the cornstarch, lemon juice, and vanilla extract. Pour this mixture over the nectarines and stir gently to combine.
- Once the crust is done baking, use a slotted spoon to transfer the nectarine mixture onto the crust. Sprinkle the remaining crumble topping evenly over the nectarines.
- Return the dish to the oven and bake for 40-45 minutes, or until the topping is golden brown.
- Allow the bars to cool completely before cutting them into squares and serving.

Tips & Tricks for Perfect Nectarine Crumble Bars
• Don’t Overbake: Be sure to keep an eye on the bars during the last few minutes of baking. You want the topping to be golden brown but not overdone.
• Add Texture: If you prefer a bit of crunch, add chopped nuts like almonds or walnuts into the crumble topping for extra texture.
• Serve Cold: These bars taste just as delicious chilled. In fact, some find that the flavors develop even more after a few hours in the fridge.
• Leftover Storage: Store any leftover bars in an airtight container in the refrigerator for up to 4 days. You can also freeze them for longer storage.
Pairing Ideas and Variations for Nectarine Crumble Bars
Nectarine Crumble Bars are perfect on their own, but if you want to take them to the next level, consider these pairing ideas:
• A scoop of vanilla ice cream or a dollop of whipped cream pairs beautifully with these bars, especially when served slightly warm.
• Serve them with a side of Greek yogurt for a tangy contrast to the sweetness of the bars.
• For a more decadent twist, drizzle caramel or chocolate sauce over the bars before serving.
Variations:
• For a gluten-free version, swap the all-purpose flour with a gluten-free flour blend and make sure all other ingredients are gluten-free.
• If you’re looking for a more vibrant flavor, try adding a bit of orange zest or cardamom to the nectarine filling.
