01 - Preheat oven to 350°F. Grease and line two 8-inch round cake pans with parchment paper.
02 - Blend strawberries and sugar in blender or food processor until smooth. Reserve 1/2 cup for cake batter and 1/4 cup for frosting.
03 - In medium bowl, sift together cake flour, baking powder, baking soda, and salt.
04 - In large bowl, beat butter, oil, and sugar together until light and fluffy, about 3 minutes.
05 - Add eggs one at a time, beating well after each addition. Mix in vanilla extract.
06 - Mix in strawberry purée and food coloring, if using, until evenly distributed.
07 - Alternately add dry ingredients and buttermilk to wet mixture, starting and ending with dry ingredients. Mix until just combined; do not overmix.
08 - Divide batter evenly between prepared pans. Smooth tops. Bake for 28–32 minutes, or until toothpick inserted in center comes out clean.
09 - Let cakes cool in pans for 10 minutes, then turn out onto wire racks to cool completely before frosting.
10 - Beat cream cheese and butter together until smooth. Gradually add powdered sugar, beating until fluffy. Mix in vanilla and strawberry purée until well combined.
11 - Place one cake layer on serving plate. Spread layer of frosting on top. Add second cake layer and coat top and sides with remaining frosting.
12 - Decorate with fresh strawberries. Chill for 30 minutes before slicing to ensure clean layers.
