Recipe Information
Ingredients
- 1.5 cups All-purpose flour
- 1.5 cups Rolled oats
- 1 cup Brown sugar
- 0.75 cup Unsalted butter (cold, cubed)
- 1 cup Granulated sugar
- 3 pieces Large eggs
- 0.75 cup Lemon juice (freshly squeezed)
- 2 tablespoons Lemon zest (finely grated)
- 0.25 cup All-purpose flour (for filling)
- 2 tablespoons Powdered sugar (optional, for garnish)
Instructions
Preheat your oven to 350°F (175°C) and line a 9x13-inch baking pan with parchment paper, leaving an overhang on the sides for easy removal.
In a large mixing bowl, combine 1.5 cups of all-purpose flour, 1.5 cups of rolled oats, and 1 cup of brown sugar. Mix well.
Add the cold cubed butter to the dry mixture. Using a pastry cutter or your fingers, blend until the mixture resembles coarse crumbs.
Press about three-quarters of the mixture firmly into the bottom of the prepared pan to form a crust. Reserve the remaining mixture for the crumble topping.
Bake the crust in the preheated oven for 10 minutes. Remove from the oven and set aside while you prepare the lemon filling.
In a medium mixing bowl, whisk together the granulated sugar, eggs, freshly squeezed lemon juice, lemon zest, and 0.25 cup of flour. Mix until smooth and well combined.
Pour the lemon filling over the pre-baked crust, spreading evenly with a spatula.
Sprinkle the reserved crumble mixture evenly over the top of the lemon filling.
Bake in the preheated oven for 25-30 minutes, or until the topping is golden brown and the filling is set.
Allow the lemon oatmeal crumble to cool completely in the pan. Once cooled, lift them out using the parchment overhang and cut into squares.
If desired, dust the squares with powdered sugar before serving for an extra touch of sweetness.
