Looking for a sweet and simple summer dessert? These Nectarine Oatmeal Crumble Bars are perfect when Nectarines are in season.

To make the crust and topping, whisk together the flour, oats, brown sugar, baking powder, salt, and cinnamon. Then add in the melted butter and vanilla extract and combine until the dough comes together. Take about 2/3 of the dough and press it down into a greased and lined 8″x8″ baking pan until it’s in a flat, even layer. Bake the crust for about 10 minutes at 350° F, and set aside the remainder 1/3 of dough.
While the crust is baking, toss the Nectarine slices with sugar. Once the crust has baked, spread the slices on top in an even layer. Then crumble and sprinkle the remaining dough on top and gently press down onto the filling. Bake for 35-40 minutes until the topping is golden brown. I love to store these Nectarine Oatmeal Crumble Bars in the fridge to eat them cold.
Some ingredients Notes
Nectarines – Using ripe nectarines when they’re in season in the summer will make these taste so fresh.
Old Fashioned Rolled Oats – These will give the crust and crumble a good texture and depth.

Nectarine Oatmeal Crumble Bars
- Prep Time: 20 minutes
- Cook Time: 45 minutes
- Total Time: 1 hour 5 minutes
- Yield: 16 bars 1x
Ingredients
- 1 1/4 cups all-purpose flour
- 3/4 cup old fashioned rolled oats
- 1/3 cup brown sugar
- 1 teaspoon baking powder
- 1/8 teaspoon salt
- 1/2 cup unsalted butter, melted
- 1 teaspoon vanilla extract
- 4 cups sliced Nectarines
- 2 teaspoons granulated sugar
Instructions
- Grease and line a 8″x8″ baking pan with parchment paper, making sure that the parchment paper hangs over the edge of the pan so that it’s easy to lift and remove the bars from the pan. Preheat the oven to 350° F.
- Whisk together the flour, oats, brown sugar, baking powder, and salt in a bowl until combined. Add in the melted butter and vanilla extract and mix until the dough comes together.
- Take about 2/3 of the dough and drop it into the lined baking pan. Press down on the dough with your fingers so that it’s in a flat, even layer covering the entire pan. Set aside the remaining 1/3 of the dough.
- Bake the crust for 10 minutes. Then, remove to slightly cool.
- In a small bowl, toss the Nectarine slices with the granulated sugar.
- Evenly spread the nectarines over the crust that’s still warm. Crumble the dough that was set aside so that it’s in small pieces. Sprinkle it on top of the filling.
- Bake the bars for 35-40 minutes. The topping should be golden brown and the filling will be bubbling. When done, place the pan on a wire rack to cool. Once completely cooled, remove the bars from the pan, cut, and serve.
