Why You'll Love This Lemon Cream Cheese Bar Recipe

If you're looking for a great recipe for lemon bars, look no further - this one's got it all.

Imagine a lemon dessert with two different elements going on.

On the bottom, you have a rich, chewy cake crust that has a hint of lemon flavor going. On the top, you have a tangy, creamy cheesecake filling that's sweet, playing perfectly off of the rich crust. These two layers together make a knock-out combination.

This is such a great recipe for summer. It's bright and fresh, but filling and comforting at the same time. It's also super simple to whip together - just mix ingredients for two layers and bake.

Ingredients, Substitutions, and Additions

A few important ingredient notes:

  • lemon cake mix - if you ever want to change the flavor of this recipe, it's so easy! Simply use a different flavor of cake mix and substitute a packet of gelatin mix (flavor of choice) for the lemonade mix. I'd recommend strawberry cake mix, orange cake mix, or even pineapple cake mix to give this recipe more depth. (See my tres leches with cake mix or my slow cooker peach cobbler for more recipes that use cake mix.)
  • cream cheese - Make sure your cream cheese is at room temperature before mixing. This will help your cheesecake layer stay nice and smooth. And, while I used full-fat cream cheese for my recipe, you can cut the fat content of the bars a little by using reduced-fat cream cheese in this recipe.
  • powdered sugar - Don't be tempted to use granulated sugar here. The powdered sugar keeps the cheesecake layer from getting super grainy.

Additions

This is a great recipe for little additions. The lemon flavor goes so well with tons of different fruits! Use the following variations to make the flavor even more complex:

  • Add frozen or fresh berries to the cheesecake layer before baking. You could mix in a cup of blueberries, strawberries, raspberries, or even cranberries to give a really fun and different element to the bars.
  • If you'd like to jazz up that lemon flavor even more, add fresh lemon juice (2 lemons worth, or ¼ cup) and/or lemon zest (2 lemons worth) to the cream cheese batter.
  • Give this dessert another texture element by topping bars with a dollop of whipped cream.
  • Sprinkle the finished lemon bars with a light layer of powdered sugar.

Step-by-Step Instructions

Step 1: For the crust layer, mix together cake mix, 1 egg, and a stick of butter in a medium bowl until smooth (it will be the consistency of a cookie dough). Press this mixture into the bottom of the prepared baking dish.

Baking Dish Sizes

I used a 7x11" glass Pyrex baking dish for this recipe. This makes for a thicker cake crust and an average-sized cream cheese layer. You would get similar results to mine with an 8x8" glass Pyrex dish.

If you'd like thinner layers, I'd suggest going with a 9x13" glass baking dish.

Step 2: For the lemon cheesecake layer, mix together the remaining ingredients (cream cheese, lemonade mix, powdered sugar, and 2 eggs) in a large bowl, using a hand mixer, until smooth. Pour this cream cheese mixture on top of the cake mix already in the glass baking pan.

Step 3: Bake the lemon cheesecake bars in a preheated oven at 325 degrees for 35-40 minutes, until the top mixture is set and the top turns golden brown. (Inside will still be slightly jiggly, but should be browned on top.) Allow bars to cool for about 30 minutes after removing them from the oven, then chill for 3-4 hours before cutting.

Storage & Freezing Instructions

Because of the cream cheese filling, you'll want to store any leftover lemon bars in the refrigerator after serving. Cover them and place them in an airtight container when storing. These should last 3-4 days in the refrigerator.

This recipe can be frozen as well. Bake as instructed, wrap bars tightly with aluminum foil and plastic wrap, and freeze for up to 6 months. When you're ready to serve them, simply thaw them in the fridge and enjoy!

Other Tips & Tricks

  • Make sure to either spray your baking dish with cooking spray or line the bottom with parchment paper. These will stick!
  • Before cutting the lemon cream cheese bars, allow them to cool in the fridge for a few hours. Use a sharp knife to make the bars' edges smooth. Fill a bowl with warm water and dunk your sharp knife in the water before cutting each bar. I prefer to chill my bars before cutting so those edges are neat.
  • Make sure you don't bake too long. Over-cooking will dry out that luscious creamy cheesecake layer - nobody wants that. These should be pulled when the top just starts to brown.

Lemon Cream Cheese Bars FAQs

Yes, because there is cream cheese in these bars, I recommend refrigerating them. Cover tightly and store for up to 3-4 days in the fridge.

The longer lemon bars cool, the more set they will be. If the bars still aren't set after 30 minutes of cooling, pop them in the fridge for an hour or two.

Yes, absolutely. Overcooking the bars will dry out the top - you don't want that. Make sure these are just cooked until the top of the bars starts to brown. In my oven, that meant a 35 minute cook time.

    I'm with you on struggling to resist the leftovers - fortunately I have 6 other mouths in my house so leftovers don't last long around here! These look delicious!

  4. I was wanted to know if you make the cake first or do you just spread the mixture?

    1. Leslie Lambert says:

      No, you won't make the cake as directed on the box. Just use the cake mix as an ingredient in the recipe!
