Preparation Steps

• Preheat the oven to 350°F. Grease and line one 8-inch square cake pan and one 8-inch round cake pan.
• In a large bowl, whisk together the flour, sugar, cocoa powder, baking soda, and salt.
• Add the eggs, oil, buttermilk, food coloring, vanilla extract, and vinegar to the dry ingredients. Mix until well combined.
• Divide the batter evenly between the prepared square and round pans.
• Bake for 30 to 35 minutes, or until a toothpick inserted into the center comes out clean. Let the cakes cool completely.
• To make the frosting, beat the cream cheese and butter together until smooth. Gradually add the powdered sugar and vanilla extract, beating until creamy.
• To assemble the heart shape, place the square cake on a large platter in a diamond shape (one corner pointing down).
• Cut the round cake in half. Place the two flat edges of the round halves against the top two angled sides of the square cake to form a heart.
• Frost the entire cake evenly with the cream cheese frosting, covering the seams.
