Ingredients

The Lemon Cake

  • Freshly milled hard white wheat flour – Provides structure and stability while still creating a tender cake. It gives the crumb enough strength to hold the frosting and strawberry decoration beautifully.
  • Freshly milled soft white wheat flour – Adds softness and lightness to the cake, creating a more delicate crumb. Combined with the hard white wheat, it produces a cake that feels both fluffy and substantial.
  • Baking powder – Helps the cake rise evenly and gives it a light, fluffy texture.
  • Baking soda – Works alongside the buttermilk to keep the crumb soft, tender, and well balanced.
  • Salt – Enhances the lemon flavor and balances the sweetness throughout the cake.
  • Salted butter – Provides richness and creates the soft, buttery texture that makes this cake so satisfying.
  • Granulated sugar – Sweetens the cake while helping create a light, delicate crumb.
  • Eggs – Add structure, richness, and lift. Separating the eggs helps create an especially airy texture.
  • Fresh lemon zest – Adds bright citrus flavor and a fresh lemon aroma in every bite.
  • Fresh lemon juice – The heart of the lemon flavor. Freshly squeezed juice gives the cake its vibrant taste.
  • Vanilla extract – Adds warmth and rounds out the citrus notes beautifully.
  • Buttermilk – Keeps the cake moist, soft, and tender while adding a subtle tang that complements the lemon.

The Lemon Buttercream

  • Unsalted butter – Forms the rich, creamy base of the frosting and creates a smooth spreadable texture.
  • Powdered sugar – Creates a fluffy buttercream with just the right amount of sweetness.
  • Fresh lemon juice – Brightens the frosting and balances the richness of the butter.
  • Fresh lemon zest – Adds little bursts of citrus flavor throughout the buttercream.
  • Heavy cream – Helps create a light, silky consistency that spreads easily over the cake.
  • Salt – A small pinch keeps the frosting from tasting overly sweet and enhances the lemon flavor.

Variations & Add-Ins

  • Blueberry border – Add fresh blueberries around the edges for extra color and a classic summer berry combination. The deep blue berries look especially beautiful against the pale lemon frosting.
  • Almond extract – Add a small pinch (about ⅛ teaspoon) to the buttercream for subtle depth and a bakery-style flavor.
  • Vanilla cake base – Replace the lemon juice and zest with vanilla for a softer, more traditional cake flavor.
  • Mini lobster cakes – Divide the batter between mini loaf pans or small cake pans for individual desserts that are perfect for gatherings.
  • Extra lemon glaze – Drizzle a simple lemon glaze over the finished cake for an additional layer of bright citrus flavor.
  • Fresh raspberry garnish – Scatter a handful of raspberries around the border before serving for a beautiful pop of color and extra summer fruit flavor.

Recipe Tips

Use room temperature buttermilk – Cold buttermilk can cause the batter to mix unevenly. Let it sit out for about 30 minutes before baking so it blends smoothly with the other ingredients.

Cream thoroughly – Beat the butter and sugar for a full 3–4 minutes. This creates air in the batter and helps produce a lighter, fluffier cake.

Don’t overmix once the flour is added – Mix only until combined to maintain a tender crumb. Overmixing can make the cake dense instead of soft.

Fold the egg whites gently – A light hand helps preserve the air you’ve whipped into them. Those air bubbles help give the cake its delicate texture.

Dry the strawberries well – Excess moisture can soften the buttercream and affect the decoration. Pat them dry thoroughly before arranging them on the cake.

Chill before decorating – Slightly chilled frosting creates a firmer surface for decorating and helps keep the strawberry pieces neatly in place.

Choose varied strawberry sizes – Larger berries work best for the claws while smaller berries create natural-looking tail segments. Having a variety makes the design easier to assemble.

Cool completely before frosting – Even a slightly warm cake can melt the buttercream. Allow the cake to cool fully before decorating for the cleanest results.

Instructions

  1. Mill the flour: Mill 126 grams hard white wheat berries and 84 grams soft white wheat berries. Whisk the freshly milled flours together to create a balanced flour blend that yields approximately 210 grams (1¾ cups) of flour. If preferred, substitute 1¾ cups all-purpose flour.
  2. Preheat the oven: Preheat to 350°F and grease a 7×9-inch baking pan. A light coating of butter or baking spray helps ensure the cake releases easily after baking.
  3. Whisk the dry ingredients: In a medium bowl, whisk together the flour, baking powder, baking soda, and salt until evenly combined. This helps distribute the leavening ingredients throughout the batter.
  4. Cream the butter and sugar: In a large mixing bowl, beat the softened butter and granulated sugar together for 3–4 minutes, until light and fluffy. The mixture should become noticeably paler in color.
  5. Add the egg yolks and citrus: Mix in the egg yolks until fully incorporated. In a separate bowl, stir together the lemon zest, lemon juice, vanilla, and buttermilk.
  6. Combine the batter: Alternate adding the dry ingredients and buttermilk mixture, beginning and ending with the flour mixture. Mix just until combined to keep the cake tender.
  7. Whip the egg whites: In a clean bowl, beat the egg whites to soft peaks. They should hold a gentle curve when the beaters are lifted.
  8. Fold in the whites: Gently fold the whipped egg whites into the batter until no streaks remain. Take your time to preserve as much air as possible.
  9. Bake: Spread the batter evenly into the prepared pan and bake for 28–35 minutes, until a toothpick inserted into the center comes out clean. Allow the cake to cool completely before frosting.
  10. Make the buttercream: Beat the butter until smooth, then gradually add the powdered sugar, lemon juice, lemon zest, salt, and cream until light, fluffy, and easily spreadable.
  11. Frost and decorate: Spread the buttercream over the cooled cake and arrange the strawberries into a lobster design. Use larger berries for the claws and smaller pieces for the body and tail.
  12. Chill and serve: Refrigerate until ready to serve. A brief chill helps the frosting set and makes cleaner slices.

Freezing & Storage

  • Refrigerator – Store loosely covered in the refrigerator for up to 24 hours for the freshest appearance. The strawberries are at their best within the first day.
  • Avoid decorating too early – Fresh strawberries are best added within a few hours of serving. This helps prevent excess moisture from softening the design.
  • Make the cake ahead – Bake and frost the cake the day before serving. Add the strawberry decoration shortly before your gathering.
  • Freeze the unfrosted cake – Wrap tightly and freeze for up to 2 months before decorating. Thaw overnight in the refrigerator before frosting.
  • Clean slices – Use a sharp knife dipped in hot water and wiped dry between cuts for neat, bakery-style slices.

Notes

Use room-temperature buttermilk – Cold buttermilk can cause the batter to mix unevenly and affect the final texture. Let it sit out for about 30 minutes before baking for the smoothest batter.
Fold the egg whites gently – The whipped egg whites help create a lighter, softer crumb. Take your time when folding them into the batter to preserve as much air as possible.
Dry the strawberries thoroughly – Excess moisture can soften the buttercream and affect the finished decoration. Pat the berries dry before arranging them on the cake.
Decorate close to serving time – For the freshest appearance, add the strawberry lobster decoration within a few hours of serving. This helps the berries maintain their shape and color.
Freshly milled or all-purpose flour both work well – The blend of hard white and soft white wheat creates a wonderfully tender crumb, but all-purpose flour can be substituted with excellent results.
