What is the Best Way to Store Lemon Cake Mix Bars

These can be stored in an airtight container at room temperature for up to 3-4 days or in the fridge for up to a week.

You can also freeze them for up to 2-3 months. Make sure you wrap them tightly in plastic wrap and then slip them into a freezer-safe container or freezer bag.

Lemon Bar Recipe Variation

  • Cake mix: If you want a more subtle lemon flavor, you can use another flavor of cake mix. A white cake mix, or yellow cake mix with a little bit of lemon extract is a good choice. And both will work well with lemon glaze.
  • Other mix-ins: If want to add just a little crunch to your bars, mini white chocolate chips or finely chopped macadamia nuts go great without overpowering the lemon flavor.
  • Additional fresh lemon flavor: To give your homemade lemon bars even more tangy flavor, add some fresh lemon zest to the dry cake and some to the glaze before it dries.
  • Glaze: If you want a thicker lemon frosting you can mix in some softened cream cheese. Just keep in mind that you don’t want a thick cream cheese frosting because the lemon bars are thinner than a sheet cake and more delicate than a brownie.

Can I Use Store-Bought Lemon Juice?

It may seem like a small thing, but fresh lemon juice just can’t be duplicated with store-bought. It makes all the difference in the fresh, tangy flavor of the dessert.

Tips For Making the Best Lemon Bars with Cake Mix

  • Avoid overmixing: Don’t overwork the batter. This can result in tough and dry bars. Mix the ingredients just until they are well combined.
  • Watch your baking time: Baking times will vary depending on your oven.  Keep an eye on the bars towards the end time.  You’ll want to remove them from the oven once they are lightly browned on the edges and the center seem to be set. 
  • Always cool before glazing: To prevent the glaze from warming up and running off the bars, let your lemon cake mix cookies completely cool before glazing. Letting the bars cool also helps them hold their shape when sliced.
  • Prevent sticking: If you’re worried about the bars sticking, you’ll get the best results by lining the bottom of your baking dish with parchment paper. This makes it easy to remove the bars from the dish and cut them into even slices.
