There's a reason why this vanilla cake recipe is the best. Adding creamy vanilla bean paste into this moist, rich cake batter creates a power-packed vanilla flavor that can't be bought in stores. Try spreading the Best Vanilla Buttercream frosting on top to finish it off. —Margaret Knoebel, Milwaukee, Wisconsin
