Why You’ll Love These 2-Ingredient Lemon Bars
- Only two ingredients: You need just a box of lemon cake mix and a can of lemon pie filling.
- Quick preparation: The batter comes together in minutes.
- Bright citrus flavor: Lemon cake mix and lemon filling create a sweet, tangy combination.
- No complicated techniques: No separate crust, frosting, or special equipment required.
- Easy to share: Cut the cooled dessert into squares for parties and gatherings.
Ingredients
- 1 box (15.25 ounces) lemon cake mix
- 1 can (21 ounces) lemon pie filling
That’s all you need for this easy dessert. Do not prepare the cake mix according to the package directions.
Instructions
Step 1: Prepare the Baking Pan
Preheat your oven to 350°F (175°C).
Lightly grease a 9-by-13-inch baking pan or line it with parchment paper, leaving a little overhang to make removing the bars easier.
Step 2: Combine the Ingredients
Add the lemon cake mix and lemon pie filling to a large mixing bowl.
Stir with a sturdy spoon or spatula until the dry cake mix is incorporated. The mixture will be thick and sticky, rather than a traditional pourable cake batter.
Avoid adding eggs, oil, or water. The recipe is designed to use only the two listed ingredients.
Step 3: Spread the Batter
Transfer the mixture into the prepared baking pan.
Use a spatula to spread it into an even layer, gently pressing the batter into the corners.
Step 4: Bake
Bake for approximately 25–35 minutes, or until the edges are lightly golden and the center looks set.
Because ovens and cake mix brands vary, begin checking around the 25-minute mark. A toothpick inserted into the center should come out without wet batter.
Step 5: Cool and Slice
Remove the pan from the oven and place it on a wire rack.
Allow the bars to cool completely before cutting. For cleaner slices, refrigerate them for about 30 minutes after cooling.
Cut into squares and serve.
Tips for Perfect Lemon Bars
- Use lemon pie filling: Lemon curd and lemon pie filling are not always interchangeable. Use the canned pie filling specified for this recipe.
- Don’t prepare the cake mix: Add the dry cake mix directly to the pie filling.
- Spread evenly: An even layer helps the bars bake consistently.
- Watch the edges: They should be lightly golden, not dark brown.
- Cool completely: Warm bars are soft and may fall apart when sliced.
- Use parchment paper: This makes lifting the cooled bars out of the pan much easier.
Easy Variations
The original recipe uses exactly two ingredients. If you want to customize it, try these optional additions:
- Powdered sugar: Dust the cooled bars lightly before serving.
- Fresh lemon zest: Add a little extra citrus aroma.
- Vanilla glaze: Drizzle a simple glaze over the cooled bars.
- Coconut: Sprinkle shredded coconut over the top before baking.
These additions are optional and are not included in the two-ingredient count.
How to Serve 2-Ingredient Lemon Bars
These bars are delicious on their own, but they also pair beautifully with:
- Fresh strawberries or raspberries
- A dollop of whipped cream
- Vanilla ice cream
- Fresh blueberries
- Hot tea or iced coffee
For a pretty dessert platter, arrange the lemon bars alongside fresh berries and small cookies.
Storage Instructions
Room temperature: Because the filling is moist, store the bars covered in the refrigerator rather than leaving them out for extended periods.
Refrigerator: Place cooled bars in an airtight container and refrigerate for up to 4 days.
Freezer: Freeze individual bars in a single layer until firm, then transfer them to a freezer-safe container with parchment between layers. Freeze for up to 2 months. Thaw overnight in the refrigerator.
Frequently Asked Questions
Can I really make lemon bars with only two ingredients?
Yes. Lemon cake mix and lemon pie filling combine to make a thick, easy batter that bakes into soft lemon dessert bars.
Do I need eggs or butter?
No. This particular shortcut recipe does not require eggs, butter, oil, or water.
Why is my batter so thick?
That is normal. Unlike traditional cake batter, this mixture is thick and sticky because the pie filling provides the moisture.
How do I know when the bars are done?
The edges should look lightly golden, and the center should be set without wet batter. Avoid overbaking, which can make the bars dry.
Can I use another flavor of cake mix?
Yes. White or yellow cake mix can be used for a different flavor, although the result will not have the same strong lemon taste.
Should lemon bars be refrigerated?
Yes. Since these bars contain moist pie filling, refrigeration is the best way to store leftovers.
