Ingredients

• 1 cup (2 sticks or 226g) unsalted butter, softened (for crust and topping)
• 1 cup granulated sugar, divided
• 2 large eggs, room temperature
• 1 teaspoon vanilla extract
• 2 cups all-purpose flour, plus more for dusting
• 1 teaspoon baking powder
• 1/2 teaspoon salt
• 4 medium ripe nectarines, peeled, pitted, and sliced about 1/4 inch thick
• 2 tablespoons lemon juice
• 1 tablespoon cornstarch

Step-by-Step Instructions

1. Preheat your oven to 375°F (190°C). Grease and line a 9×13 inch baking pan with parchment paper, leaving an overhang on the sides for easy removal.
2. Prepare the Crust: In a large bowl or the bowl of a stand mixer, cream together 1 cup of the softened butter and 3/4 cup of the granulated sugar until light and fluffy, about 3 minutes. Beat in one egg and the vanilla extract until just combined.
3. In a separate bowl, whisk together the flour, baking powder, and salt. Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined and a thick dough forms. Do not overmix.
4. Press about two-thirds of the dough evenly into the bottom of the prepared baking pan to form the crust. Set the remaining one-third of the dough aside for the topping.
5. Prepare the Filling: In a medium bowl, gently toss the sliced nectarines with the lemon juice and cornstarch until lightly coated.
6. Spread the nectarine filling evenly over the prepared crust.
7. Prepare the Topping: In the small bowl where you set the remaining dough, add the remaining 1/4 cup of sugar. Use your fingers or a pastry blender to cut the remaining chilled dough into the sugar until a coarse, crumbly mixture forms. Sprinkle this crumble evenly over the nectarine layer.
8. Bake for 40 to 45 minutes, or until the edges are golden brown and the fruit filling is bubbly.
9. Let the bars cool completely in the pan on a wire rack before cutting (this is crucial for clean slices—about 2 hours). Once cooled, use the parchment paper overhang to lift the bars out and cut into squares.

Expert Tips / Pro Tips

For the best texture in these Homemade Nectarine Bars, ensure your crust dough is kept slightly cool. If the butter melts too much while mixing, the crust will spread too thinly and become greasy. Using room-temperature eggs helps emulsify the wet ingredients properly. Always chill the bars completely before slicing; cutting warm bars will result in a messy, gooey square.

Variations & Substitutions

Feel free to substitute the nectarines with other seasonal stone fruits like peaches or plums. If you want an extra layer of flavor, add 1/2 teaspoon of ground cinnamon or a pinch of nutmeg to the fruit mixture before topping. For the topping, instead of a crumble, you can press the remaining dough evenly over the fruit to create a cohesive top layer, sometimes called a shortbread bar.

Serving Suggestions

These bars are delightful served slightly warm or at room temperature. They pair wonderfully with a dollop of fresh whipped cream or a scoop of vanilla bean ice cream. For a simple presentation, dust the cooled bars lightly with powdered sugar just before serving.

Storage, Freezing & Reheating

Store leftover Homemade Nectarine Bars in an airtight container at room temperature for up to 3 days, or refrigerate for up to 5 days. To freeze, ensure the bars are completely cooled. Place them in a freezer-safe, airtight container separated by parchment paper. They freeze well for up to 3 months. Thaw overnight in the refrigerator before serving. Reheating is not generally necessary, but if desired, briefly warm individual squares in a toaster oven.

FAQ

Can I use frozen nectarines instead of fresh?

If using frozen nectarines, do not thaw them. Toss them directly with the lemon juice and cornstarch, adding an extra teaspoon of cornstarch to absorb the excess moisture released during baking. You may need to add 5-10 minutes to the baking time.

Why are my bars crumbly when I try to cut them?

The most common reason for crumbly bars is failing to let them cool completely. The butter and flour structure needs time to set firmly after coming out of the oven. Always wait at least two hours before attempting to slice.

Can I make this recipe ahead of time?

Yes, these bars are excellent for making a day ahead. In fact, they often taste better the next day as the fruit juices meld with the crust. Store them covered tightly at room temperature.

Ingredients Method Notes

Ingredients

  

For the Crust & Topping

• 1 1/2 cups All-purpose flour
• 1/2 cup Granulated white sugar
• 1/2 teaspoon Baking powder
• 1/4 teaspoon Salt
• 3/4 cup Unsalted butter Cold, cut into cubes

• 1/4 cup Brown sugar, packed
• 1 tablespoon Cornstarch
• 1 teaspoon Lemon juice
• 1/2 teaspoon Ground cinnamon

Method

 

Instructions

1. Preheat oven to 350°F (175°C). Line a 9×9 inch metal baking pan with parchment paper, leaving an overhang on two sides for easy removal.
2. Prepare the crust/topping mixture: In a medium bowl, whisk together the flour, granulated sugar, baking powder, and salt. Cut in the cold, cubed butter using a pastry blender or your fingers until the mixture resembles coarse crumbs.
3. Press about two-thirds (2/3) of the crumb mixture firmly into the bottom of the prepared baking pan to form the crust. Reserve the remaining one-third (1/3) for the topping.
4. Prepare the filling: In a separate bowl, gently toss the sliced nectarines with the brown sugar, cornstarch, lemon juice, and cinnamon until evenly coated.
5. Spread the nectarine filling evenly over the crust layer in the pan. Sprinkle the reserved one-third of the crumb mixture evenly over the fruit filling.
6. Bake for 45 to 50 minutes, or until the topping is golden brown and the filling is bubbly. Let the bars cool completely in the pan on a wire rack (at least 2 hours) before lifting out using the parchment overhang and slicing into squares.

Notes

For a richer flavor, use brown sugar in the crust mixture instead of granulated sugar. Make sure the bars are fully cooled before slicing; otherwise, the filling will ooze out. These are excellent served warm with a scoop of vanilla bean ice cream.
