These bright and tangy lemon pie bars offer a punch of citrusy flavors and are topped with cake crumble. Grab a fork because these babies are thick, saucy, and will remind you of an old-fashioned lemon meringue pie sitting on a chewy delicious cookie.
Lately, the lemons have been calling my name. When I was making the filling for my lemon meringue pie I knew I had to find another way to use it. I love being about to make a recipe once, but find other ways to totally repurpose it. Like when I make lemon curd, we spread it on breakfast crepes but I usually make an extra batch to fill cupcakes too.
So technically I used this filling for my pie but then changed up a few things so I could make lemon bars too.

How to Make Easy Lemon Pie Bars
Prepare pan. Grease a 9×13 baking pan with cooking spray or line it with parchment paper. Preheat the oven to 350 degrees.
Mix and bake the crust. Beat together the cake mixes, eggs, and oil in a medium bowl by hand or with an (electric) stand mixer. Set aside half of the mixture for later, and press the remaining dough into the prepped baking dish. Bake for 15 minutes.
Make the lemon pie filling. Stir together the sugar, water, and cornstarch in a medium saucepan. Whisk in the large egg yolks. Bring the filling to a simmer over low heat whisking constantly. Cook until it’s thick and boils on low for at least 1 minute.
Add filling to bars. Remove the mixture from the heat and stir in the lemon juice, lemon zest, and butter. Pour the filling over the crust of the bars.
Sprinkle on the topping. Sprinkle the reserved dough from earlier in clumps over the filling.
Bake the bars. Place the lemon squares bake in the oven to bake for 15 to 20 minutes or just until the tops begin to brown. Allow for the bars to cool completely.
Drizzle the glaze. In a small bowl, whisk together the milk and powdered sugar to make a glaze. Pour over top of the cooled bars. Cut into squares with a sharp knife and serve.
Fun Fact
Egyptians once believed that eating lemons offered protection from several forms of poison.
- For a thinner filling and sturdier cookie bar: use half of the lemon pie filling.
- Instead of vanilla cake mix, you could use white, yellow, or lemon cake mix.
- To make a lemon glaze: use lemon juice instead of the milk. If you want to keep the milk for the glaze, you can add 1-2 drops of lemon oil for an extra punch of flavor.
- For a more tart lemon pie filling: use Eureka lemons
- To make a sweeter, mellow filling: use Meyer lemons
- If you want to use up the leftover egg whites, make my lemon meringue pie!
- Store on the counter for 2-3 days or freeze for up to 1 month.
You could use a graham cracker crust for the lemon bars, except there wouldn’t be a crumble topping. In that case, you could reduce the cooking time and dust with powdered sugar. You may also want to try a shortbread crust.
Make sure you are using a sharp knife. When cutting, slice in one complete stroke. Make sure the bars are completely set and cooled before cutting.
