How to Make Easy Lemon Crumble Bars
Ingredients
- 1 box cake mix (any flavor works, but vanilla or yellow is best)
- 1/2 cup unsalted butter, melted
- 1 can lemon pie filling
Helpful Notes:
- Cake mix can be found in the baking aisle of any grocery store.
- For a richer flavor, consider using a butter cake mix.
- Ensure the butter is melted before mixing; this helps achieve a crumbly texture.
Directions
- Preheat the oven to 350°F (175°C). Ensure your oven is fully heated for even baking.
- In a mixing bowl, combine the cake mix and melted butter until crumbly. Use a spatula or your hands to create a mixture that resembles wet sand, ensuring all the cake mix is moistened.
- Press half of the mixture into the bottom of a greased baking dish. Use your fingers or the bottom of a measuring cup to press the mixture firmly and evenly, creating a solid crust.
- Spread the lemon pie filling evenly over the crust. Use a spatula to smooth the pie filling into a thin layer, allowing it to settle naturally into the crust.
- Sprinkle the remaining crumb mixture on top of the lemon filling. Distribute it evenly to create a lovely topping that turns golden while baking.
- Bake for about 25-30 minutes or until golden brown. You’ll know they’re ready when they are bubbling at the edges and have a fragrant aroma.
- Allow to cool before cutting into bars. This step helps firm them up, making slicing easier.

How to Serve Easy Lemon Crumble Bars
These lemon crumble bars are best enjoyed at room temperature, allowing all the flavors to meld beautifully. For an appetizing presentation, cut them into uniform squares and arrange them on a platter.
Pair these sweet treats with a cup of tea or coffee for a delightful afternoon snack or serve them at a festive gathering with a scoop of vanilla ice cream on the side. A dusting of powdered sugar or a sprig of mint can elevate your serving, making them perfect for special occasions like birthday parties or summer picnics.
How to Store Easy Lemon Crumble Bars
To keep your lemon crumble bars fresh, store them in an airtight container in the refrigerator. They’ll stay delicious for about 5-7 days.

When ready to enjoy, let them thaw in the refrigerator overnight. To preserve that crumbly texture, reheat them gently in the oven at 325°F for about 5-10 minutes.
