Ingredients
For the Oatmeal Crumble
- 2 cups old-fashioned rolled oats
- Note: Avoid quick oats—they’re too soft
- 1½ cups all-purpose flour
- ¾ cup brown sugar packed
- ½ teaspoon baking soda
- ½ teaspoon salt
- ¾ cup unsalted butter melted
For the Lemon Filling
- ¾ cup granulated sugar
- 2 tablespoons all-purpose flour
- 2 large eggs
- ½ cup fresh lemon juice about 2–3 lemons
- 1 tablespoon lemon zest
Instructions
1. Preheat and Prep
- Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, leaving an overhang for easy removal.
2. Make the Oat Crumble
- In a large bowl, mix oats, flour, brown sugar, baking soda, and salt. Pour in melted butter and stir until the mixture is evenly moistened and crumbly.
3. Form the Crust
- Press about two-thirds of the oat mixture firmly into the bottom of the prepared pan to create an even layer.
4. Bake the Crust
- Bake for 12–15 minutes, until lightly golden and set. Remove from oven and let cool slightly.
5. Prepare the Lemon Filling
- In another bowl, whisk together granulated sugar and flour. Add eggs, lemon juice, and zest, whisking until smooth.
6. Assemble the Bars
- Pour the lemon filling evenly over the warm crust. Sprinkle the remaining oat mixture over the top, gently pressing it down slightly.
7. Bake Again
- Return to the oven and bake for 22–25 minutes, or until the top is golden and the filling is set.
8. Cool and Slice
- Let the bars cool completely in the pan. For clean slices, chill for 1–2 hours before cutting.
