Step-by-step instructions
Preheat your oven to 350°F (175°C) and line an 8×8-inch baking pan with parchment paper.
In a large bowl, mix together the flour, sugar, baking powder, and salt.
Cut the cold, cubed butter into the dry mixture using a pastry cutter or fork until it resembles coarse crumbs.
Stir in the egg and vanilla extract until the mixture is combined and crumbly.
Press half of this crumb mixture into the bottom of the prepared baking pan to form a crust.
In another bowl, whisk together the sweetened condensed milk, fresh lemon juice, and lemon zest until smooth.
Pour the lemon mixture over the crust in the baking pan.
Sprinkle the remaining crumb mixture over the top of the lemon filling.
Bake for 30-35 minutes, or until the top is golden brown and set.
Allow the bars to cool completely before slicing them into squares.

Keeping leftovers fresh
To keep any leftover Lemon Crumb Bars fresh, store them in an airtight container in the refrigerator. They can typically last for up to one week.
