  • Lemon Juice: Provides tangy, fresh citrus flavor.

Lemon Squares Preparation Method

Step 1: Prepare Baking Station

Set your oven to 350°F. Grab a 9×13 inch baking dish and give it a quick spray with cooking spray or line it with parchment paper for easy removal.

Step 2: Create Crumbly Crust

Grab a mixing bowl and combine:
  • Flour
  • Sugar
  • Pinch of salt

Drizzle melted coconut oil into the dry ingredients and mix until the texture looks like coarse sand. Press this mixture firmly into the prepared baking dish. Slide the dish into the oven and bake until the edges turn a beautiful golden brown, about 15-20 minutes.

Step 3: Whip Up Tangy Filling

In a separate bowl, blend together:
  • Sugar
  • Flour
  • Eggs
  • Fresh lemon zest
  • Freshly squeezed lemon juice

Whisk everything until smooth and silky. Once the crust is out of the oven, carefully pour this bright, zesty mixture over the golden base.

Step 4: Bake to Perfection

Return the dish to the oven and bake for another 20-25 minutes. You’ll know it’s ready when the filling looks set and slightly jiggly in the center. Let the bars cool completely at room temperature.

Step 5: Finish with Flair

Dust the cooled bars generously with powdered sugar. Slice into squares and serve. These sunshine-inspired treats are perfect for sharing with friends and family.

Helpful Ideas for Lemon Squares

  • Zest Like a Pro: Use fresh, unwaxed lemons for the most vibrant and intense citrus flavor in your lemon squares.
  • Prevent Soggy Crust: Let the crust cool and set slightly before adding the lemon filling to maintain a crisp, golden base.
  • Slice with Ease: Chill the lemon squares completely in the refrigerator for at least 2 hours before cutting to get clean, sharp edges.
  • Dairy-Free Delight: Swap coconut oil for butter to keep the recipe dairy-free and add a subtle tropical hint to the crust.
  • Sugar Sensibility: Adjust the powdered sugar dusting to your taste, using less for a more tart experience or more for extra sweetness.

Best Way To Store Sunny Lemon Squares

  • Seal lemon squares in an airtight container, placing parchment paper between layers to prevent sticking. Keep refrigerated for up to 5 days, maintaining their fresh texture and tangy flavor.
  • Wrap individual squares tightly in plastic wrap, then place in a freezer-safe container. Freeze for maximum 2-3 months, ensuring no moisture penetrates the packaging.
  • Transfer frozen lemon squares to the refrigerator overnight, allowing gradual defrosting. Remove plastic wrap and let them reach room temperature before serving for best taste and texture.
  • Warm slightly in a preheated oven at 300°F for 5-7 minutes, or enjoy chilled directly from the refrigerator for a refreshing dessert experience.

Sunny Lemon Squares Accompaniments

  • Pair Creamy Beverages: Smooth, cold milk or light vanilla latte perfectly balances the tangy lemon squares with their rich, gentle flavor.
  • Complement Herbal Teas: Chamomile or lavender tea softens the zesty citrus notes, creating a delicate and refreshing dessert experience.
  • Match Sparkling Whites: Crisp prosecco or light sauvignon blanc cuts through the sweetness, enhancing the bright lemon flavor with elegant effervescence.
  • Enhance with Fresh Fruits: Fresh berry compote or passion fruit sorbet adds a complementary citrusy dimension, amplifying the lemon squares' vibrant profile.

Lemon Square Twists to Try

  • Gluten-Free Citrus Squares: Replace wheat flour with almond flour or gluten-free blend for a celiac-friendly version. Use coconut oil as a safe binding agent.
  • Vegan Lemon Bars: Substitute eggs with silken tofu or aquafaba. Use plant-based butter or coconut oil instead of dairy ingredients. Maintain the bright lemon flavor with fresh citrus zest.
  • Low-Sugar Zesty Squares: Swap regular sugar with monk fruit sweetener or stevia. Reduce overall sugar content while keeping the tangy lemon profile. Use a lighter base of ground nuts and dates for the crust.
  • Dairy-Free Sunshine Squares: Eliminate dairy completely by using coconut oil or plant-based margarine. Keep the lemon essence vibrant with fresh juice and zest. Ensure crust and filling remain creamy and smooth.

FAQs

  • Why use coconut oil in the crust?

Coconut oil provides a rich, subtly sweet flavor and creates a crisp, golden crust that’s lighter than traditional butter-based crusts. It also adds a hint of tropical essence to the lemon squares.

  • How do I get the perfect lemon flavor?

Use fresh lemon zest and freshly squeezed lemon juice. The zest contains essential oils that provide intense citrus flavor, while fresh juice ensures a bright, tangy taste that’s not overly artificial or flat.

  • Can I make these gluten-free?

Yes, substitute the regular flour with a gluten-free all-purpose flour blend. Make sure to use one that has xanthan gum or add 1/2 teaspoon of xanthan gum to help bind the ingredients and maintain the right texture.

  • What's the best way to cut clean, neat squares?

Refrigerate the lemon squares for at least an hour before cutting. Use a sharp knife dipped in hot water and wiped dry between each cut to create smooth, precise edges.

Ingredients

Scale

Main Ingredients:

  • 6 large eggs
  • 1 cup fresh squeezed lemon juice
  • 2 1/2 cups granulated sugar
  • 1 cup coconut oil

Produce:

  • 2 teaspoons lemon zest

Baking & Spices:

  • 2 1/3 cups flour
  • 3/4 teaspoon salt
  • 1 teaspoon vanilla extract

Instructions

  1. Prepare the oven environment by heating to 350°F (175°C) and preparing the baking dish with a light coating of grease or parchment paper.
  2. Create a delicate crust foundation by blending flour, sugar, and a pinch of salt until the mixture resembles coarse crumbs, then incorporate melted coconut oil to bind the ingredients.
  3. Press the crumbly crust mixture evenly into the prepared baking dish, ensuring a uniform layer that will provide a crisp base for the tangy filling.
  4. Bake the crust in the preheated oven for 15-20 minutes, watching for a gentle golden transformation that signals the perfect preliminary stage.
  5. While the crust bakes, craft the zesty lemon filling by whisking together sugar and flour to eliminate any potential lumps.
  6. Introduce fresh eggs to the sugar mixture, then infuse with vibrant lemon zest and freshly squeezed lemon juice, creating a smooth, sunshine-colored custard.
  7. Once the crust emerges golden and slightly firm, carefully pour the lemon filling over the hot surface, ensuring complete and even coverage.
  8. Return the dish to the oven and bake for an additional 20-25 minutes, watching for a subtle set and a slight jiggle in the center that indicates perfect consistency.
  9. Allow the lemon squares to cool completely at room temperature, which helps the filling stabilize and develop its signature texture.
  10. Finish by delicately dusting the cooled dessert with a light veil of powdered sugar, transforming the squares into an elegant, inviting treat.

Notes

  • Customize the crust by swapping coconut oil with butter for a classic flavor or using gluten-free flour for a dietary-friendly version.
  • Enhance lemon intensity by adding extra zest or using Meyer lemons for a sweeter, more aromatic citrus profile.
  • Prevent soggy bottom by ensuring the initial crust is fully baked and golden before adding the lemon filling, creating a crisp foundation.
  • Make ahead and refrigerate for cleaner, more precise cuts when serving, allowing the squares to set completely and develop a firmer texture.
