Tips & Variations

- Use frozen blueberries if fresh aren’t available; just thaw and drain excess liquid before layering.
- For a zestier lemon flavor, add a bit more lemon zest to the filling.
- To make cutting easier, refrigerate the bars for 1 hour before slicing.
Storage
Store the bars in an airtight container in the refrigerator for up to 5 days. They can be served cold or at room temperature. To reheat, let them sit at room temperature briefly or warm gently in a low oven for a few minutes.

FAQs
Can I use frozen blueberries instead of fresh?
Yes, frozen blueberries work well. Just thaw them fully and drain any excess juice before adding to the bars to avoid a soggy crust.
How do I get a crumbly but firm shortbread crust?
Be sure to use softened butter and mix just until combined with the flour. Pressing the dough firmly into the pan before baking helps create a solid base that holds together after baking.

Ingredients
Shortbread Crust
- 1 cup unsalted butter, softened to room temperature
- 3/4 cup granulated sugar
- 1 1/2 tsp vanilla extract
- 1/4 tsp sp almond extract
- 2 1/2 cups all purpose flour
Filling
- 1 14oz can sweetened condensed milk
- 6 Tbsp fresh lemon juice
- 1 Tbsp fresh lemon zest
- 2 cups fresh blueberries
Topping
- Powdered sugar, if desired
Instructions
- Preheat Oven and Prepare Pan: Preheat the oven to 350 degrees Fahrenheit and line a 9×9 inch baking dish with parchment paper or aluminum foil. Set aside for easy removal of the bars.
- Cream Butter: Using a stand mixer, hand mixer, or food processor, cream the softened unsalted butter until it becomes light and fluffy, which helps create a tender crust.
- Add Sugar: Add the granulated sugar to the creamed butter and mix until well combined and smooth.
- Add Extracts: Stir in the vanilla extract and almond extract to infuse the dough with aromatic flavors.
- Incorporate Flour: Gradually add the all-purpose flour and mix until a crumbly dough forms. The mixture should hold together when pressed but remain a bit crumbly. Set this dough aside.
- Make Filling: In a separate bowl, whisk together the sweetened condensed milk, fresh lemon juice, and lemon zest until smooth and well combined.
- Assemble Base Layer: Press half of the shortbread dough evenly into the prepared baking dish, ensuring a uniform layer to serve as the crust.
- Add Filling: Spread the lemon custard filling evenly over the shortbread crust, distributing it carefully to cover the base completely.
- Add Blueberries: Arrange the fresh blueberries in an even layer over the lemon filling to add bursts of juicy freshness.
- Add Topping: Sprinkle the remaining shortbread dough over the blueberries as a crumbly topping.
- Bake: Place the pan in the preheated oven and bake for 30-35 minutes, or until the top is lightly golden brown and the filling is bubbling around the edges.
- Cool: Remove from the oven and allow the bars to cool completely in the pan to set properly. They can also be chilled if preferred for a firmer texture.
- Serve: Dust the cooled bars with powdered sugar if desired, slice into squares, and serve.
Notes
- Make sure the butter is at room temperature for easier creaming and better texture in the crust.
- Using fresh lemons provides the best citrus flavor in the filling.
- Press the shortbread dough firmly into the pan to avoid crumbling when eating.
- Chilling the bars after baking enhances their flavor and makes them easier to cut.
- These bars keep well in an airtight container in the refrigerator for up to 4 days.
- You can substitute frozen blueberries if fresh are not available, but fresh is preferred for texture.
