Everyone has been creating their own version of this viral Chantilly Berry Cake, and this sheet-pan version couldn’t be easier. It starts with a light, moist cake made with a Betty Crocker™ vanilla cake mix. Whole eggs are swapped for egg whites to make a light cake, and sour cream is added for extra moisture. The cake gets brushed with a syrup for even more moisture. It is then covered in a mascarpone and cream cheese frosting and topped with fresh berries. It’s simple to make and perfect for a crowd.

    In a small saucepan, heat syrup ingredients over medium heat until the sugar is dissolved, stirring occasionally. Use a pastry brush to brush a thin layer of syrup over the cake. Not all syrup will be used at this point; reserve remaining syrup.
