Preheat the Oven: Preheat your oven to 350°F (175°C). Grease and flour an 8-inch round cake pan or line it with parchment paper to prevent sticking.
Mix Dry Ingredients: In a medium bowl, whisk together the all-purpose flour, baking powder, and salt. Set aside.
Cream Butter and Sugar: In a large mixing bowl, beat together the softened butter and granulated sugar until light and fluffy. This should take about 2-3 minutes using an electric mixer on medium speed.
Add Eggs and Lemon: Beat in the eggs one at a time, ensuring each is fully incorporated before adding the next. Stir in the lemon zest, followed by the vanilla extract.
Alternate Wet and Dry Ingredients: Gradually add the dry ingredients to the wet ingredients in three parts, alternating with the pink lemonade and buttermilk. Start and end with the dry ingredients. Mix gently until just combined, being careful not to overmix.
Transfer to Pan: Pour the cake batter into the prepared cake pan and smooth the top with a spatula to ensure an even layer.
Bake: Place the pan in the preheated oven and bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs attached.
Cool: Allow the cake to cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely.
Frost the Cake: Once the cake has completely cooled, spread a layer of frosting over the top using a spatula. You can also frost the sides if you prefer a fully frosted cake.
Serve: Slice the cake into 12-16 pieces and serve as a refreshing and vibrant dessert.
