Scale
- For the Crust & Topping:
- 7 tablespoons (99g) unsalted butter, softened
- 3/4 cup (150g) packed light or dark brown sugar
- 1 teaspoon vanilla extract
- 1 cup (125g) all-purpose flour
- 1 teaspoon baking powder
- 1/4 teaspoon salt
- 1 cup (85g) old-fashioned or quick oats (not instant)
- For the Lemon Filling:
- 1 can (14 oz) full-fat sweetened condensed milk
- 6 tablespoons (90ml) fresh lemon juice (about 2 lemons)
- 1 tablespoon lemon zest (about 1 lemon)
Instructions
- Preheat oven to 350°F (177°C). Line an 8-inch square baking pan with parchment paper.

Store at room temperature for up to 2 days or in the fridge for 1 week. Freeze in layers with parchment for up to 3 months. Add extra zest or a drop of lemon extract for more citrus punch.
