- 3 large eggs (room temperature)
- 3 cups all-purpose flour
- 1 tbsp baking powder
- 1 tsp fine sea salt

Buttercream Frosting Ingredients
- 1½ cups unsalted butter (very soft)
- 5½ cups powdered sugar (sifted)
- 1½ tsp vanilla extract
- 6 tbsp double cream
- ½ cup freeze-dried raspberries (finely ground)
- 3 tsp strawberry jelly powder (e.g., Strawberry Jell-O or any packaged Strawberry Gelatin Dessert)
Decoration
- Fresh raspberries
- Freeze-dried raspberries
- Lemon slices
Instructions
- Preheat and Prepare Pans: Preheat the oven to 350ºF. Grease and line three 8-inch cake pans with parchment paper, ensuring the sides are well coated to prevent sticking.
- Mix Lemon Sugar: In a large bowl, rub together the granulated sugar and lemon zest until the mixture feels like damp sand and emits a strong lemon aroma to release the oils from the zest.
- Cream Butter and Sugar: Add softened butter to the lemon sugar and beat for 2–3 minutes until the mixture is light, fluffy, and pale, which helps create a tender cake crumb.
- Add Eggs: Incorporate eggs one at a time, mixing well after each addition. If the batter looks curdled, add a tablespoon of flour to bring it back together.
- Mix Dry Ingredients: In a separate bowl, whisk together the flour, baking powder, and salt.
- Mix Wet Ingredients: In a jug, whisk the double cream, vegetable oil, lemon juice, and vanilla extract.
- Combine Ingredients: Add dry and wet ingredients to the butter mixture alternately, starting and ending with dry ingredients as follows: one-third dry, half wet, one-third dry, remaining wet, and remaining dry.
- Mix Batter: Mix on low speed just until smooth; avoid overmixing to keep the cake tender.
- Divide Batter: Evenly divide the batter between the three cake pans (about 492g per pan if weighing).
- Bake Cakes: Bake for 25–28 minutes, or until lightly golden and a touch to the center springs back.
- Bake Layers Sequentially: If baking with two pans, keep remaining batter at room temperature and bake the third layer once the first two are done.
- Cool Cakes: Let the cakes cool in pans for 10 minutes, then turn out onto a wire rack to cool completely.
- Prepare Raspberry Powder: Grind freeze-dried raspberries into a fine powder; optionally sieve to remove seeds.
- Beat Butter: Beat butter for the frosting until smooth and pale.
- Add Sugar Gradually: Gradually add sifted powdered sugar while mixing until fully combined and smooth.
- Add Flavorings: Mix in vanilla extract, raspberry powder, and strawberry jelly powder thoroughly.
- Add Cream: Gradually add double cream until the buttercream is smooth, soft, and spreadable but not too loose. Beat 2–3 more minutes for volume and light texture.
- Assemble Cake: For each cake layer, spread a thin layer of buttercream, pipe a buttercream dam border around the edge, then fill the center with ½ cup raspberry jam. Repeat for all layers.
- Crumb Coat and Chill: Apply a thin crumb coat of buttercream to the entire cake, then chill for 20–30 minutes.
- Final Frosting and Decoration: Apply a final layer of buttercream smoothly over the cake. Decorate with fresh raspberries, freeze-dried raspberries, and lemon slices.
- Serve: Slice the cake, serve, and enjoy the refreshing lemon and raspberry flavors.
Notes
- Ensure all ingredients such as butter, eggs, and cream are at room temperature for best mixing results.
- Do not overmix the batter to prevent a dense cake; stop as soon as smooth.
- Using fresh lemon zest is key to getting an intense lemon flavor in the cake.
- The buttercream can be adjusted for thickness by varying the amount of double cream.
- Freeze-dried raspberries add intense raspberry flavor without extra moisture in the frosting.
- Chilling the cake after crumb coating helps achieve a clean final frosting layer.
- Store leftovers covered in the refrigerator and bring to room temperature before serving for best texture.
