                   3-Ingredient Lemon Bars

These 3-Ingredient Lemon Bars are an easy, bright dessert with a soft, tender center and plenty of sweet citrus flavor. Made with just three simple ingredients, they’re perfect when you want a homemade treat without measuring a long list of ingredients.

These easy lemon bars are wonderful for spring and summer gatherings, potlucks, holidays, bake sales, or an afternoon dessert with coffee or tea.

Ingredients

• 1 box (15.25 ounces) lemon cake mix
• 2 large eggs
• ½ cup unsalted butter, melted

The three ingredients are: lemon cake mix, eggs, and butter.

How to Make 3-Ingredient Lemon Bars

1. Prepare the Oven

Preheat your oven to 350°F (175°C).

Line an 8×8-inch or 9×9-inch baking pan with parchment paper, leaving some overhang along the sides. Lightly grease the parchment.

2. Make the Lemon Batter

Pour the lemon cake mix into a large mixing bowl.

Add the eggs and melted butter.

Stir until everything is completely combined. The mixture will be considerably thicker than regular cake batter, which is exactly what you want for soft dessert bars.

3. Spread in the Pan

Transfer the lemon mixture to the prepared baking pan.

Use a spatula or the back of a spoon to spread it into an even layer, making sure the batter reaches the corners.

4. Bake

Bake for approximately 18–25 minutes, or until the edges are lightly golden and the center looks set.

Avoid overbaking. The bars should remain soft and slightly chewy in the center rather than becoming dry and cake-like.

5. Cool Completely

Remove the pan from the oven and allow the lemon bars to cool completely in the pan.

Once cool, use the parchment-paper overhang to lift them onto a cutting board.

Cut into squares and serve.

Tips for the Best Lemon Bars

Don’t prepare the cake mix according to the directions printed on the box. For this recipe, use only the dry cake mix, eggs, and melted butter listed above.

Allow the melted butter to cool slightly before adding it to the eggs.

The batter will be thick and sticky. A lightly greased spatula can make it easier to spread evenly in the pan.

Watch the bars carefully toward the end of baking. Removing them once the center is set helps preserve their soft texture.

Most importantly, let them cool completely before slicing. Warm bars are much more likely to fall apart.

Easy Variations

If you don’t need to keep the recipe strictly three ingredients, there are several easy ways to dress up these lemon bars.

Dust the cooled bars with powdered sugar for a classic-looking finish.

You can also add fresh lemon zest to intensify the citrus flavor or drizzle the finished bars with a simple powdered-sugar-and-lemon glaze.

White chocolate chips are another delicious addition if you prefer a sweeter dessert.

How to Serve Lemon Bars

Serve these lemon bars at room temperature or slightly chilled.

They’re especially good with fresh berries, whipped cream, vanilla ice cream, coffee, or hot tea.

For parties and potlucks, cut them into smaller squares so they’re easy to pick up and serve.

How to Store Lemon Bars

Store the cooled bars in an airtight container at room temperature for about 2 days or refrigerate them for up to 5 days.

If stacking the bars, place parchment or wax paper between the layers to prevent sticking.

You can also freeze them for up to 2 months. Wrap individual bars well before placing them in a freezer-safe container.

Frequently Asked Questions

Can I use yellow cake mix instead?

Yes, but lemon cake mix provides a much stronger lemon flavor. If using yellow cake mix, adding lemon zest or lemon extract would improve the citrus flavor, although that would increase the ingredient count.

How do I know when the lemon bars are finished?

The edges should be lightly golden and the center should look set. A toothpick inserted near the center can have a few moist crumbs but shouldn’t come out covered in wet batter.

Why are my lemon bars dry?

They were probably baked too long. Since ovens vary, begin checking them around the 18-minute mark.

Can I make them ahead?

Yes. These bars are an excellent make-ahead dessert because they’re easier to slice once completely cooled.
