Frosted Lemon Bars Instructions

Making Frosted Lemon Bars is a delightful experience that brings your kitchen to life with the scent of lemons. I always find joy in every step, from mixing the crust to pouring the creamy filling. Here’s how to create your own batch of sunshine:
Preheat your oven to 350℉. This is a crucial step as it ensures the crust will bake evenly and become perfectly golden.
In a large bowl, use an electric mixer to combine 2 cups of all purpose flour, 1 cup of salted butter (softened), and ½ cup of powdered sugar. Mix until well combined, forming a crumbly dough. The consistency should be similar to wet sand.
Press the crust mixture into a 9×13-inch baking pan evenly. Take your time to ensure it’s packed tightly, which will create a sturdy base for the filling.
Bake the crust for 20 minutes or until it’s light golden brown. You’ll know it’s ready when you see a slight color change and can smell the buttery aroma filling your kitchen.
While the crust is baking, prepare the filling. In another large bowl, whisk together 2 cups of granulated white sugar, 4 large eggs, 4 tablespoons of all purpose flour, 2 tablespoons of freshly squeezed lemon juice, and ¼ teaspoon of salt until smooth. The mixture should be light and frothy.
Once the crust has baked, pour the lemon filling over it evenly. Make sure to spread it out so that it covers the entire surface.
Bake for an additional 25 minutes. You want the filling to set, and the edges should start to slightly brown.
Remove from the oven and let the filled lemon bars cool completely. I usually set them on a wire rack to speed up the cooling process.
In a large bowl, combine 3 cups of sifted powdered sugar, ½ cup of salted butter (at room temperature), 4 ounces of cream cheese, and 3 tablespoons of heavy whipping cream. Use an electric mixer to combine until smooth and creamy.
Once the lemon bars are completely cool, carefully spread the frosting over the top. Take your time to create an even layer.
Finally, sprinkle lemon zest on top for garnish, if desired. Refrigerate until firm, then slice into squares and serve. Enjoy the bliss of Frosted Lemon Bars!
Things Worth Knowing
- Cooling Time Matters: Allow your bars to cool completely before frosting to prevent the frosting from melting into the filling.
- Use Fresh Lemons: Freshly squeezed lemon juice makes a noticeable difference in flavor compared to bottled lemon juice.
- Crust Consistency: Ensure the crust is firm before pouring in the filling; this helps in holding the bars together.
- Chill Before Serving: Letting the bars chill in the fridge enhances the flavors and helps set the filling.
Ways to Customize

Customizing Frosted Lemon Bars can lead to a lot of fun variations. Here are some great ways to add your own twist!
- Add Berries: Toss in some fresh blueberries or raspberries into the lemon filling for an added burst of flavor.
- Graham Cracker Crust: Substitute the all-purpose flour crust with a graham cracker crust for a different texture and flavor.
- Different Citrus: Experiment with lime or orange juice instead of lemon for a unique taste.
- Herbs: Infuse the filling with a hint of fresh basil or mint for a surprising and refreshing twist.
- Extra Frosting: Don’t hold back on the frosting—feel free to double the frosting ingredients for those who love it extra creamy!
- Gluten-Free Option: Use a gluten-free flour blend to make these bars suitable for those with gluten sensitivities.
- Spiced Flavor: Add a pinch of cinnamon or nutmeg to the frosting for a warm, spiced flavor that complements the lemon.
