Oatmeal Topped Peach Crisp

Topping:
¾ cup packed light brown sugar
¾ cup rolled oats
⅓ cup plus 2 tbsp flour
¾ tsp cinnamon
6 tbsp cold butter (¾ stick), cut into small pieces

Filling:
⅓ cup packed light brown sugar
1 tbsp freshly squeezed lemon juice
1½ tsp cornstarch
¼ tsp vanilla
2 lbs, ripe but firm peaches (about 5 medium, halved, pitted and cut into ½” thick slices)

Heat the oven to 400 degrees.

Topping: Place all of the ingredients in a large bowl. With your fingertips, blend the butter pieces into the dry ingredients until large clumps form and the flour and butter are completely incorporated, about 3 minutes. Crumble the clumps into small pieces the size of kidney beans, then refrigerate the streusel while you make the filling.

Filling: Place the brown sugar, lemon juice, cornstarch, and vanilla in a large bowl and whisk to combine. Add the peaches and stir until evenly coated.

Transfer the mixture to an 8”x8” glass or ceramic baking dish and arrange it in an even layer. Sprinkle the reserved topping evenly over the peaches.

Bake until the topping is browned and crisp, about 20 to 25 minutes. Place the dish in a wire rack to cool for at least 30 minutes before serving.
