Two Ingredients and a Little Kitchen Magic

When my pantry was down to the last few staples, I tried this trick on a whim, and the pan was empty before the evening ended.

Learn more about DanyRecipes and why I love turning almost nothing into something sweet. These 2 ingredient lemon bars use a boxed cake mix and a can of lemon pie filling for a soft, tangy treat that costs just a few dollars.

Why This Budget Magic Works

The cake mix already holds the flour, sugar, and leavening, and the lemon pie filling brings the moisture, the tang, and the sweetness. Stirred together and baked, they turn into a chewy, soft bar with real lemon flavor.

This lemon bars recipe fits a standard 9×13 pan and cuts into about 24 squares, so it stretches a long way on a small budget. It is one of my favorite lemon desserts for last minute plans, and it sits nicely beside my chewy thumbprint lemon curd cookies on a dessert plate.

Just Two Ingredients

• 1 box (15.25 ounces) lemon or yellow cake mix
• 1 can (21 ounces) lemon pie filling

Optional: a light dusting of powdered sugar for serving, which is a pantry bonus rather than a core ingredient.

Easy Steps to Magic Bars

STEP 1

Heat the oven to 350°F and line a 9×13 pan with parchment, leaving an overhang on two sides.

STEP 2

Pour the dry cake mix and the lemon pie filling into a large bowl.

STEP 3

Stir with a sturdy spoon until no dry streaks remain and the batter looks thick and slightly lumpy.

STEP 4

Spread the batter evenly into the pan with a spatula, smoothing the top.

STEP 5

Bake for 25 to 30 minutes until the top is golden and a toothpick comes out with just a few moist crumbs.

STEP 6

Cool completely on a rack, then lift out and slice into squares.

Serving Ideas and Easy Twists

• Dust with powdered sugar right before serving for a bakery style finish.
• Stir a tablespoon of fresh lemon zest into the batter for extra zing.
• Pair with my crispy shortbread lemon curd cookies for a buttery crunch beside the soft bars.
• Top with a simple glaze of powdered sugar and a splash of lemon juice.
• Serve warm with a scoop of vanilla ice cream for a quick dessert.

Ingredients

  

Lemon Bar Batter

• 1 box lemon or yellow cake mix 15.25 ounces, dry mix
• 1 can lemon pie filling 21 ounces

Optional Garnish

• powdered sugar for dusting before serving

Equipment

• 9×13-inch Baking Pan
• Parchment paper
• Large Mixing Bowl
• Sturdy Spoon
• Spatula
• Wire Cooling Rack

Method

 

1. Preheat the oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, leaving an overhang on two sides for easy removal.
2. Pour the dry cake mix and lemon pie filling into a large mixing bowl.
3. Stir with a sturdy spoon until no dry streaks remain and the batter looks thick and slightly lumpy.
4. Spread the batter evenly into the prepared baking pan using a spatula. Smooth the top.
5. Bake for 25 to 30 minutes, until the top is golden and a toothpick inserted into the center comes out with just a few moist crumbs. Begin checking at 25 minutes to prevent overbaking.
6. Transfer the pan to a wire rack and allow the bars to cool completely. Lift them out using the parchment overhang and slice into approximately 24 squares.

Notes

Pro Tips:

• Use a sturdy spoon because the batter will be thick and heavy.
• Line the pan with parchment paper to make removing the bars easier.
• Start checking for doneness at 25 minutes because ovens vary.
• Avoid overbaking to keep the bars soft and chewy.
• Allow the bars to cool completely before slicing.
• Wipe the knife between cuts for neat squares.
• Add a pinch of salt to enhance the lemon flavor.

Serving Suggestions: Dust with powdered sugar, drizzle with a simple glaze made from powdered sugar and lemon juice, or serve warm with vanilla ice cream.

Variations: Add a tablespoon of fresh lemon zest for extra citrus flavor. Blueberry, cherry, and raspberry pie fillings can replace lemon pie filling while keeping the same approximate 21-ounce quantity.

Smaller Batch: For an 8×8-inch pan, use half the cake mix and half the pie filling. Bake for approximately 20 to 25 minutes, checking for doneness. Measure the ingredients by weight for better accuracy.

Storage: Cover and store at room temperature for up to 2 days or refrigerate for up to 5 days. Freeze individually wrapped squares for up to 2 months.

Troubleshooting: If the center is gummy, the bars may need additional baking time. Bake until a toothpick inserted into the center comes out with only a few moist crumbs. Cool completely before cutting.

Texture: These bars are softer and more cake-like than traditional custard lemon bars, with a pleasantly chewy texture.

Pro Tips

• Use a sturdy spoon, since the batter is thick and heavy.
• Line the pan with parchment so the sticky bars lift out cleanly.
• Check for doneness at 25 minutes, since ovens vary and overbaking dries the bars.
• Let the bars cool completely before cutting for neat, tidy squares.
• Wipe your knife between cuts for clean edges.
• Add a pinch of salt if you want the lemon flavor to pop.

FAQs

Are these bars like classic custard lemon bars?
No, they are softer and more cake-like, with a chewy texture instead of a firm custard. They are a quick, budget friendly cousin of the classic.

Can I use a different pie filling?
Yes, blueberry, cherry, or raspberry filling all work with the same method. Keep the can size at about 21 ounces.

How should I store the bars?
Cover and keep at room temperature for up to 2 days, or refrigerate for up to 5 days. Freeze wrapped squares for up to 2 months.

Why are my bars gummy in the middle?
They likely needed a few more minutes in the oven. Bake until a toothpick shows only a few moist crumbs, and cool fully before slicing.

Can I make these in an 8×8 pan?
Yes, use half the cake mix and half the pie filling, and bake for 20 to 25 minutes. Measure the mix by weight for the best results.
