Preparation Steps

• Preheat oven to 350°F (175°C). Grease and flour two 9-inch round baking pans.
• In a medium bowl, whisk together flour, sugar, baking soda, and salt.
• In a large bowl, cream together butter and sugar until light and fluffy. Beat in eggs one at a time, then stir in vanilla.
• Gradually add the dry ingredients to the wet ingredients, alternating with the buttermilk, beginning and ending with the dry ingredients. Mix until just combined.
• Stir in purple food coloring until desired shade is reached.
• Divide batter evenly between prepared pans. Bake for 30-35 minutes, or until a wooden skewer inserted into the center comes out clean.
• Let cakes cool in pans for 10 minutes before inverting onto a wire rack to cool completely.
