Ingredients
Oat Crust &
- Topping
- 1 cup (80 g) quick-cooking oats
- 1½ cups (180 g) all-purpose flour
- 1 cup (200 g) light brown sugar, packed
- ¼ teaspoon baking soda
- ¼ teaspoon baking powder
- ¾ cup (1½ sticks / 170 g) unsalted butter, melted
Lemon Filling
- 1 can (14 ounces) sweetened condensed milk
- 2 large egg yolks
- ½ cup (115 g) freshly squeezed lemon juice (about 5 lemons)
- 1 teaspoon lemon zest
- ⅛ teaspoon kosher salt
Directions
Prepare the Pan
Preheat oven to 350°F (175°C) and line a 9×9-inch pan with parchment paper, leaving an overhang on the sides for easy removal.
Make the Oat Crust
In a large bowl, combine oats, flour, brown sugar, baking powder, and baking soda. Pour melted butter over the mixture and mix until crumbly. Be careful not to overmix so it remains crumbly for the topping.
Measure out ½ of the mixture (about 2 cups) and set aside for the topping. Pour the remaining mixture into the lined baking dish and press firmly to the bottom of the pan.
Bake 12-15 minutes, or until golden brown. Set aside to cool slightly while you make the lemon filling.
Make the Lemon Filling
In a large bowl, whisk together sweetened condensed milk, egg yolks, lemon juice, lemon zest, and salt until smooth and creamy.
Assemble and Bake
Spread the lemon mixture evenly over the baked oat crust. Crumble the reserved oat mixture over the top.
Bake 20-25 minutes or until the edges are golden brown and the filling is set.
Cool and Chill
Let the bars come to room temperature, then refrigerate for at least 1 hour before slicing. Use the parchment overhang to lift the bars out of the pan for clean, easy cutting.
