Martha Stewart Lemon Bars Recipe Ingredients
- ½ cup (1 stick) unsalted butter, room temperature, plus more for pan
- ½ cup confectioners’ sugar, plus more for dusting
- ¼ teaspoon salt
- 1 cup all-purpose flour (spooned and leveled)
- 4 large egg yolks
- 1 can (14 ounces) sweetened condensed milk
- ¾ cup fresh lemon juice (from about 3 lemons)

How To Make Martha Stewart Lemon Bars Recipe
- Preheat oven and prepare pan: Preheat oven to 350°F. Butter an 8-inch square baking pan and line the bottom with parchment paper, leaving overhang on two sides. Butter the parchment as well.
- Make the crust: In a bowl, beat butter, confectioners’ sugar, and salt with an electric mixer until light and fluffy. Add flour and mix on low until just combined. Press dough into the bottom and ½ inch up the sides of the prepared pan. Prick all over with a fork.
- Bake the crust: Bake crust for 15 to 20 minutes until lightly golden.
- Make the filling: In a large bowl, whisk together egg yolks, sweetened condensed milk, and lemon juice until smooth.
- Bake with filling: Pour lemon filling over hot crust and return pan to oven. Bake for 25 to 30 minutes, until filling is set. Let cool completely in the pan.
- Chill and slice: Refrigerate for at least 2 hours or up to 3 days. Use parchment overhang to lift bars from the pan. Cut into 16 squares and dust with confectioners’ sugar.

Recipe Tips

The bars likely didn’t bake long enough. Make sure the filling is fully set before removing from the oven. - How to get clean slices:
Wipe your knife clean between cuts and use a sharp blade for the best presentation. - Can I double this recipe?
Yes, use a 9×13-inch pan and adjust baking times slightly.
