Signature of Duncan Hines A family favorite, the Perfectly Moist Strawberry Supreme Naturally Flavored Cake Mix creates a wonderful and moist strawberry cake. It's simple to prepare a consistently moist cake thanks to the velvety cake batter. Just toss in the eggs, water, and vegetable oil after adding the baking mix. Transfer onto a pan and bake according to the recipe's suggested timing. To make a rich sheet cake with frosting and fresh berries, prepare this strawberry cake mix. It can also be used to produce creative cake creations like cake pops, or as a cupcake mix.
