Shortbread Crust
- 1 stick butter, melted
- ½ cup granulated sugar
- 1 teaspoon vanilla extract
- 1 teaspoon lemon zest (about 1 lemon)
- 1 ¼ cup all purpose flour
Lemon Blueberry Filling
- 2 large egg yolks
- 14 ounces sweetened condensed milk
- ½ cup lemon juice
- 1 teaspoon lemon zest (about 1 lemon)
- 1 ½ cups blueberries, fresh or frozen (if frozen, do not thaw)
Shortbread Crust
Preheat oven to 350℉.
In a bowl, whisk together the butter, sugar, vanilla, and lemon zest until smooth.
1 stick butter, melted, ½ cup granulated sugar, 1 teaspoon vanilla extract, 1 teaspoon lemon zest (about 1 lemon)
Then, add the flour and stir until all ingredients come together in a crumbly dough.
1 ¼ cup all purpose flour
Press the dough evenly into the bottom of a parchment-lined 8 x 8 baking dish.
Bake on the middle rack of the oven for 20 minutes.
Let cool to room temperature.
Lemon Blueberry Filling
In another bowl, whisk together the egg yolks and sweetened condensed milk.
2 large egg yolks, 14 ounces sweetened condensed milk
Stir in the lemon juice and zest.
½ cup lemon juice, 1 teaspoon lemon zest (about 1 lemon)
Lastly, gently fold in the blueberries.
1 ½ cups blueberries, fresh or frozen (if frozen, do not thaw)
Once the shortbread crust has cooled, pour the lemon mixture over top of the crust in the pan.
Bake for 15 minutes or until set when you give the pan a shake.
Let cool to room temperature and then refrigerate for at least 2 hours. Patience is key!
Sprinkle with a dusting of powdered sugar just before serving.
Enjoy!
👩🍳 Pro Tip: To cut clean squares, make sure: (a) the bars have completely cooled before attempting to slice them, and (b) use a sharp knife and wipe the knife clean between each cut.
🧺 Storage: When kept covered in the refrigerator, these lemon blueberry bars will stay delicious for several days.
😃 Delicious Variations
- Crust - Switch things up and make a graham cracker crust instead. Just pulse some graham crackers in a food processor until they form crumbs, then mix with a little melted butter. Press this mixture into the bottom of the pan and bake as usual.
- Topping - Set aside a little bit of the shortbread dough and sprinkle it on top of the lemon blueberry filling for a crumble topping.
- Fruit additions - Besides blueberries, try mixing in other fruits, like raspberries, blackberries, strawberries, kiwis, peaches, mangoes, or any other soft fruit.
- Filling - Feeling adventurous? Why limit yourself to lemon bars? Try making the filling with other citrus fruits like lime, orange, grapefruit, kumquat, yuzu, or any other citrus your heart desires!
- Pan size & shape - If you don't have an 8" x 8" pan handy, use a 9 x 13 (just be aware that the lemon filling won't be as thick) or even a tart pan!
