Step-by-Step Instructions:
1. Prepare Your Cake Pans and Oven
Preheat your oven to 350°F (175°C). Grease and flour three 8-inch round cake pans, or line them with parchment paper circles. This ensures your beautiful birthday cake layers won’t stick.
2. Mix Dry Ingredients
In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set this aside for a moment. This step ensures an even distribution of leavening agents for fluffy birthday cake layers.
3. Cream Wet Ingredients
In a large bowl, using an electric mixer, cream together the softened butter and granulated sugar until light and fluffy. Beat in the eggs one at a time, then mix in the lemon zest and lemon juice.
4. Combine Wet and Dry Ingredients
Gradually add the dry ingredients to the wet ingredients, alternating with the buttermilk, beginning and ending with the dry. Mix until just combined, being careful not to overmix the batter. Gently fold in the floured blueberries.
5. Bake the Cake Layers
Divide the batter evenly among the three prepared cake pans. Bake for 30-35 minutes, or until a wooden skewer inserted into the center comes out clean. Let the cakes cool in the pans for 10 minutes before inverting them onto a wire rack to cool completely.
6. Prepare the Cream Cheese Frosting
While the cakes cool, beat the softened cream cheese and butter together in a large bowl until smooth. Gradually add the sifted powdered sugar, then mix in the vanilla extract and optional lemon juice until the frosting is light and fluffy. This delicious frosting is perfect for any birthday cake.
7. Assemble the Cake
Once the cake layers are completely cool, place one layer on your serving plate. Spread about a third of the frosting evenly over the top. Repeat with the second cake layer and more frosting, then top with the third layer. Frost the top and sides of the entire cake with the remaining frosting, smoothing it out for a beautiful finish.
Variation Ideas:
- Raspberry Lemon: Substitute raspberries for blueberries.
- Coconut Lemon: Add shredded coconut to the cake batter and sprinkle some on top.
- Mini Cakes: Use smaller cake pans to make individual birthday cake portions.
Storage Instructions:
Store your Lemon Blueberry Layer Cake in an airtight container in the refrigerator for up to 3-4 days. You can also freeze individual slices, tightly wrapped, for up to 1 month. Thaw frozen slices in the refrigerator overnight before serving.
