Creating this Gluten-Free Lemon Cake with Lemon Cream Cheese Frosting is a simple process if you follow these key steps:

1. Preheat the Oven: Start by preheating your oven to 350°F (175°C). Prepare two 9-inch round cake pans by greasing and lining the bottoms with parchment paper.
2. Mix Dry Ingredients: In a mixing bowl, whisk together the gluten-free flour, baking powder, and salt. Set aside.
3. Cream Butter and Sugar: In a large mixing bowl, beat the softened butter and granulated sugar together until light and fluffy, about 3-4 minutes.
4. Add Eggs: Add eggs one at a time, mixing well after each addition. This will ensure a well-blended mixture.
5. Incorporate Wet Ingredients: Mix in the buttermilk, lemon zest, lemon juice, and vanilla extract until just combined.
6. Combine Mixtures: Gradually add the dry ingredients to the wet ingredients, mixing until the batter is smooth and well combined.
7. Pour into Pans: Divide the batter evenly between the prepared cake pans, smoothing the tops.
8. Bake: Place in the preheated oven and bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
9. Cool Cakes: Remove from the oven and let the cakes cool in the pans for 10-15 minutes. Then, transfer them to wire racks to cool completely.
10. Prepare the Frosting: In a large mixing bowl, beat the softened cream cheese and butter together until creamy. Gradually add powdered sugar, mixing well after each addition. Finally, mix in lemon juice, zest, and a pinch of salt to taste.
11. Assemble the Cake: Once the cakes are cooled, place one layer on a serving plate. Spread a generous amount of frosting on top. Place the second layer on top and frost the top and sides of the cake as desired.
12. Decorate: Optionally, garnish with additional lemon zest or edible flowers for a stunning presentation.
