Ingredients

For the Cake:

• 3/4 cup unsalted butter (12 Tbsp), softened
• 1 cup granulated sugar
• 3 large eggs, room temperature
• 2 cups all-purpose flour
• 2 1/2 tsp baking powder
• 2 Tbsp poppy seeds, sifted to remove debris
• 1 Tbsp lemon zest (from 2 large lemons)
• 1 Tbsp lemon juice
• 1 tsp vanilla extract
• 1/2 cup buttermilk, room temperature

For the Lemon Buttercream Frosting:

• 1 cup unsalted butter (2 sticks), softened
• 4 oz cream cheese, softened
• 4 cups powdered sugar
• 3 Tbsp lemon juice
• 1 tsp vanilla extract

Instructions

Making the Cake:

1. Preheat the oven to 350°F (175°C) and position the rack in the center. Grease two 9-inch cake pans and line the bottoms with parchment paper.
2. In a large mixing bowl, use an electric mixer to cream together the softened butter and sugar on high speed for 2 minutes until light and fluffy.
3. Add the eggs one at a time, mixing just until incorporated after each addition.
4. In a separate bowl, whisk together the flour, baking powder, and poppy seeds.
5. Gradually mix in half of the dry ingredients, stirring just until combined.
6. Add the lemon juice, lemon zest, and vanilla extract, mixing briefly to incorporate.
7. With the mixer on low speed, pour in the buttermilk, followed by the remaining dry ingredients, and mix until smooth and lump-free.
8. Divide the batter evenly between the prepared cake pans and smooth the tops.
9. Bake for 20-23 minutes or until a toothpick inserted in the center comes out clean.
10. Let the cakes cool in the pans for 10 minutes, then transfer to a wire rack to cool completely before frosting.

Making the Lemon Buttercream Frosting:

1. In a large mixing bowl, beat the softened butter on high speed for 2 minutes until smooth and creamy.
2. Add the softened cream cheese and continue beating until fully blended and smooth.
3. Gradually add the powdered sugar, followed by the lemon juice and vanilla extract.
4. Beat on high speed for about 5 minutes until the frosting is light, fluffy, and well combined.

Assembling and Frosting the Cake:

1. Place one cooled cake layer on a serving plate and spread 1/3 of the frosting evenly over the top.
2. Position the second cake layer on top, flat side up, and spread another 1/3 of the frosting over the top and sides.
3. If desired, sprinkle the edges of the cake with poppy seeds.
4. Use the remaining frosting to pipe decorative swirls on top, garnishing with lemon slices for a finishing touch.

Tips

• For extra moisture, brush the cake layers with a simple syrup made of lemon juice and sugar before frosting.
• Ensure all ingredients, especially eggs and buttermilk, are at room temperature for a smooth batter.
• Sift the powdered sugar before adding it to the frosting to prevent lumps.
• Store the cake in an airtight container in the refrigerator for up to 4 days.

Variations and Substitutions

• Citrus Swap: Substitute orange or lime zest for a different citrus twist.
• Dairy-Free Option: Use plant-based butter and dairy-free buttermilk (almond milk + lemon juice).
• Gluten-Free Version: Replace all-purpose flour with a gluten-free 1:1 baking blend.
• Extra Flavor: Add a teaspoon of almond extract for a unique flavor variation.

FAQs

Can I make this cake ahead of time? Yes! You can bake the cake layers a day in advance and store them wrapped in plastic wrap at room temperature. Frost the cake just before serving.

Why is my cake dense instead of fluffy? Overmixing the batter can lead to a dense cake. Mix only until the ingredients are combined.

Can I use store-bought frosting? You can, but homemade lemon buttercream provides the best flavor and texture.

What if I don’t have buttermilk? Substitute with 1/2 cup milk mixed with 1/2 Tbsp lemon juice or vinegar and let it sit for 5 minutes before using.
