I am always trying to sharing the easiest of recipes with you. I get that constantly cooking and baking can be a LOT (unless you absolutely love being in the kitchen, then more power to you!

These lemon bars are really easy and won’t require any fresh lemons or lemon zest. They are quick and delicious and great for a dessert of after school snack.

Classic lemon bars generally have a buttery shortbread crust and are made with fresh lemon juice and meyer lemons or regular lemons. You will need to simply mix the lemon pie filling and lemon cake mix in a large bowl or medium bowl, bake and serve at room temperature. This will be one of your favorite lemon desserts.

When they first come out of the oven you can put the cooled bars on a wire rack for cooling. The lemon flavor of these bars is just so good! These are the best lemon bars, and when you top them with confectioners’ sugar — magic!

It’s a super easy dessert especially when you are running low on time. These easy lemon bars are perfect for lemon lovers. You won’t have to worry about melted butter, all purpose flour, or cleaning the bowl of a stand mixer.

These lemon squares are great for bake sales and are just so much more fun than plain old chocolate chip cookies. To transport these or keep them for the next day you can put them in an airtight container with plastic wrap. If you want to separate multiple batches you can use parchment paper.

Make sure you have a prepared pan ready for your perfect lemon bars. These may not be traditional lemon bars but the end results are just as good.These homemade lemon bars are great for bridal showers or even baby showers!
