Ingredients
Scale
Crust and Crumble
- 1 cup Unsalted Butter, softened
- 1 cup Light or Dark Brown Sugar
- 1 teaspoon Vanilla Extract
- 2 cups All-Purpose Flour
- 1 teaspoon Baking Powder
- 1/2 teaspoon Salt
- 3 cups Old-Fashioned Oats
Lemon Filling
- 1 can Sweetened Condensed Milk (approximately 14 ounces)
- 1/3 cup Lemon Juice (from about 2 lemons)
- 1 tablespoon Lemon Zest (from about 1 lemon)
Instructions
- Preparation: Preheat your oven to 350°F (177°C) and line an 8-inch square baking pan with parchment paper to prevent sticking and facilitate easy removal.
- Make the crust mixture: Beat the softened butter and brown sugar together until creamy and smooth, then add vanilla extract and mix until fully incorporated to create a rich base for the crust.
- Mix dry ingredients: In a separate bowl, combine the all-purpose flour, baking powder, salt, and old-fashioned oats, stirring until the mixture becomes crumbly with an even distribution of ingredients.
- Form and pre-bake the crust: Press slightly more than half of the crumbly oat mixture firmly and evenly into the bottom of the prepared baking pan. Bake this crust for 12 minutes to set it before adding the filling.
- Prepare the lemon filling: In a bowl, whisk together the sweetened condensed milk, lemon juice, and lemon zest until the filling is smooth and homogenous, ready to pour over the crust.
- Assemble bars: Pour the lemon filling over the hot pre-baked crust, spreading it evenly to the edges. Then, sprinkle the remaining crumble mixture evenly on top of the lemon filling for a crunchy topping.
- Bake the assembled bars: Return the pan to the oven and bake for an additional 22 to 25 minutes, or until the topping is golden and set.
- Cool and slice: Allow the bars to cool completely on a wire rack; this helps the filling set firm so the bars slice cleanly. Once cooled, lift the bars out using the parchment paper and cut into 9 squares.
Notes
- For best results, ensure the butter is softened but not melted to achieve a creamy crust mixture.
- Use fresh lemons for juicing and zesting to maximize the tangy lemon flavor.
- Allow the bars to cool completely before cutting to prevent the filling from oozing.
- Store bars in an airtight container at room temperature for up to 3 days, or refrigerate for up to a week.
- These bars can also be frozen for up to 2 months; thaw in the refrigerator before serving.
