What you need

Ingredient Notes

• Flour - You can use either gluten free flour or regular flour for this recipe. I used Bob's Red Mill All Purpose Gluten Free Flour.

• Butter - Softened unsalted butter works great. If you want to make this recipe without dairy, you can use dairy free buttery spread.

• Lemon Oil - I used pure lemon oil (food grade) to make it extra lemony. You can find it on Amazon. If you can't find it, you can substitute the zest of one lemon.

• Lemon Juice - It's best to use fresh lemon juice but if you don't have it, you can use bottled lemon juice instead.

• Eggs - Large eggs work best.

How to make classic Lemon Bars

1) The crust comes together very easily by mixing up some room temperature butter or margarine, flour, powdered sugar and salt. A wooden spoon works well.

2) Heat oven to 350°. Press into a greased 9-inch square aluminum pan, then bake or 15 minutes.

3) Meanwhile, make the creamy lemon filling (eggs, sugar, lemon juice, lemon oil or zest, flour and baking powder) in a large bowl and pour over warm crust. Bake for 25 more minutes.

4) Let cool, then sprinkle with powdered sugar. Cut into squares with a sharp knife and serve cooled bars.

Frequently Asked Questions

Do I have to use the lemon oil? No, you don't have to use lemon oil. You can substitute the lemon zest of one lemon instead, if you prefer.

Can I make this recipe dairy free? Yes, just use dairy free buttery spread instead of butter.

Expert tips

• Air Bubbles - Don't worry if you see white air bubbles on top of the lemon bars. It's just air from mixing the eggs, that's rising to the top. Simply dust with powdered sugar.

• Make Ahead - If you want to make the bars ahead of time, you can refrigerate them the day before you serve them. Then dust with powdered sugar when ready to serve.

• Freezing Tips - You can freeze your homemade lemon bars once they've been cooled and refrigerated overnight. Wrap in plastic wrap and place in a sealed airtight container or freezer bag and freeze for up to 3 months. Then thaw and enjoy later.
