Lemon Sheet Cake

If you’re searching for a dessert that brings bright, fresh flavor and effortless presentation to the table, a lemon sheet cake stands out. This cake offers an inviting citrus tang balanced with gentle sweetness, all nestled in a moist, buttery crumb. As a bonus, sheet cakes are straightforward to make and serve—ideal for potlucks, family gatherings, or simply brightening a weekday evening.

Let’s dive into each stage, from selecting ingredients and measuring out lemon zest, to tips for baking, decorating, and storing for lasting freshness.

Why Lemon Sheet Cake?

Lemon sheet cake has universal appeal. The naturally tangy profile shines with each bite, making it a crowd-pleaser for lemon lovers and dessert fans alike. Unlike layered cakes, sheet cakes deliver a relaxed approach: they transport easily in the pan, slice cleanly, and look enticing even without elaborate decoration.

You get a generous slab of cake crowned with a simple glaze that soaks in just enough for a satisfyingly soft bite every time. Whether served upright on plates or cut into handheld bars, this cake never disappoints.

Ingredient Overview

Building a vibrant lemon sheet cake depends on simple pantry staples and fresh citrus. Here’s what you’ll need, with a quick reference table for amounts:

Ingredient Purpose
All-purpose flour Structure, light crumb
Baking powder & soda Even rise, tender texture
Salt Flavor, balances the lemon
Granulated sugar Sweetens, aids browning
Unsalted butter Richness, soft crumb
Large eggs Binding, moisture
Fresh lemons (juice/zest) Bold citrus flavor, aroma
Vanilla extract Depth, warmth
Sour cream or buttermilk Tang, moist texture
Powdered sugar Smooth, sweet glaze

Sourcing Your Lemons

Opt for fresh, plump lemons—unwaxed if possible—so you can zest and juice them easily. Zest captures fragrant oils, so use a microplane to avoid the bitter white pith beneath the yellow skin. Juice the lemons last to maximize their liquid and vibrant flavor. Bottled lemon juice can’t match the punch of fresh.

Step-By-Step: Making Lemon Sheet Cake

Every baker has their rhythm, but these steps create optimal results for a cake with bright citrus and melt-in-your-mouth texture.

1. Prep the Pan

  • Grease a 9×13-inch baking sheet or pan.
  • Line the bottom with parchment to ensure smooth removal.
  • Lightly dust with flour if desired.

This double layer—fat and parchment—guarantees your cake won’t stick, even if you pour the glaze on later.

2. Mix Dry Ingredients

  • In a bowl, whisk together the flour, baking powder, baking soda, and salt.
  • Use a fork or whisk for even distribution—no clumps means a uniform crumb.

3. Cream Butter and Sugar

  • In a separate bowl, beat softened unsalted butter with granulated sugar.
  • Mix until it looks pale and fluffy, which incorporates air for a light texture.

Hand mixers or stand mixers on medium speed do the trick. Whipping for about three minutes helps.

4. Add Eggs, Lemon, and Vanilla

  • Crack in the eggs one at a time, mixing gently after each.
  • Add lemon zest and vanilla extract.
  • Pour in fresh lemon juice.

Folding these ingredients in at this stage helps distribute the lemon without deflating the mixture.

5. Alternate Wet and Dry

  • Add dry ingredients to the butter mixture in three parts, alternating with the sour cream or buttermilk.
  • Start and finish with dry ingredients.

Stir until just combined—over-mixing leads to dense cake.

6. Pour and Bake

  • Spread the batter evenly in the prepared pan.
  • Bake at 350°F (175°C) for 30-35 minutes.

Test for doneness: a toothpick inserted in the center should come out with only a few moist crumbs attached.

7. Cool Before Glazing

  • Allow the cake to cool in the pan for 10 minutes.
  • Lift out and place on a wire rack until fully cooled.

Rushing this step can melt the glaze and affect texture.

Making the Lemon Glaze

Classic lemon sheet cake is topped with a simple lemon glaze—a slick, glossy layer that amplifies citrus flavor. This is easier than frosting but just as satisfying.

  • Whisk together powdered sugar and freshly squeezed lemon juice until smooth.
  • The glaze should be pourable but thick enough to slowly run off a spoon.

Pour over the cooled cake. Tilt the cake gently if you’d like even coverage, or use a spatula for a rustic look. Let it set for about 20 minutes before slicing.

Expert Techniques and Baker’s Tips

A lemon sheet cake excels in simplicity, but a few careful steps make all the difference. Consider these when baking:

  • Room Temperature Ingredients: Butter, eggs, and dairy blend best at room temperature. This creates an even batter for a softer crumb.
  • Use a Light-Colored Pan: Dark pans bake faster and may brown the cake’s sides more than you’d like. A light pan keeps everything tender.
  • Fresh Zest Is Key: Always zest lemons just before baking. Pre-zested citrus loses its vibrancy quickly.
  • Don’t Skip Parchment: This makes lifting and slicing a breeze.
  • Cool Thoroughly Before Glazing: If the cake is warm, the glaze melts and disappears.

Variations

Lemon sheet cake serves as a blank canvas for creativity:

  • Citrus Medley: Substitute half the lemon juice and zest with orange or lime for a deeper citrus note.
  • Berry Swirl: Drop spoonfuls of raspberry or blueberry preserves and swirl gently into the batter before baking.
  • Herbed Glaze: Stir in finely chopped fresh thyme or basil into the glaze for an elevated twist.
  • Cupcake Conversion: Divide batter among lined muffin tins and bake for 18-20 minutes for portable treats.

Serving Suggestions

Slice the cooled, glazed cake into squares or rectangles. For casual events, leave the cake in the pan for easy transport.

Pair lemon sheet cake with:

  • A dollop of whipped cream or vanilla ice cream
  • Fresh berries served on the side
  • A dusting of extra lemon zest for visual flare

This cake also complements a hot cup of tea or a chilled glass of lemonade.

Storing and Freezing

Sheet cakes stay moist for days, especially when stored correctly. To keep your lemon cake at its peak:

  • Room Temperature: Cover the cake or pan tightly with plastic wrap. It keeps well for up to three days.
  • Refrigeration: For extra freshness, especially in warmer climates, refrigerate covered cake. Allow it to come to room temperature before serving for the best texture.
  • Freezing: To freeze, wrap unglazed cake tightly in two layers of plastic, then foil. Store for up to two months. Thaw overnight in the fridge, then glaze before serving.

If you freeze glazed cake, expect some moisture on thawing. For best results, add glaze after defrosting.

Lemon Sheet Cake FAQ

Can I make this cake ahead?
Yes. Bake the cake and store it, unglazed, for 2-3 days at room temperature or up to 2 months frozen.

Can I substitute yogurt for sour cream?
Yes. Greek yogurt works well and contributes moisture, with a slight tang similar to sour cream.

How do I keep the cake extra moist?
Generous sour cream or buttermilk in the batter, and proper storage, keep each bite tender.

Does this recipe double?
Absolutely. Use two pans, or a half-sheet pan for a party.

Lemon sheet cake captures the best of both worlds: effortless baking and bold, fresh flavor. Its no-fuss assembly allows you to focus on bright flavors and soft, fragrant crumb. Whether served for a big celebration or tucked away for a quiet moment with coffee, this cake brings sunshine to any table. Baking one means sharing a slice of joy—quite literally—with anyone lucky enough to grab a piece.

Ingredients

  • 2 tablespoons lemon zest (about 2 large lemons)
  • 1/4 cup freshly squeezed lemon juice (1-2 large lemons)

  • 2 cups granulated sugar
  • 3-4 cups powdered sugar, sifted

Instructions

  1. Preheat the oven to 350 degrees Fahrenheit (175°C). Grease a 9x13-inch baking pan with butter or cooking spray, line it with parchment paper, and set aside.
  2. In a large bowl, whisk the flour, baking powder, baking soda, and salt until well blended.
  3. In a separate large bowl, beat the sugar and butter with an electric mixer until light and fluffy - about 5 minutes. Add the eggs one at a time, beating well after each addition until smooth. Finally, add the lemon zest, lemon juice, and vanilla, and stir to combine.
  4. Alternate adding the dry ingredients and sour cream, starting and ending with the flour. Stir by hand with a spatula until just combined and no streaks of flour are visible.
  5. Pour the batter into the prepared pan, smooth the top with a spatula, and bake for 30-35 minutes or until a toothpick inserted in the middle comes out clean. Remove from the oven and let cool on a wire rack.
  6. While the cake is cooling, add 3 cups of powdered sugar to a large bowl. Slowly whisk in the lemon juice until smooth and lump-free. Add more powdered sugar, as needed.
  7. Pour the glaze over the cooled cake and spread evenly over the surface. Garnish with lemon zest, if desired, and chill for 20-30 minutes or until the glaze is set. Then slice, serve, and enjoy!
