Rather than individual strawberry shortcakes, serve this family-style showstopper for dessert. Our version might look time-consuming, but one major shortcut (relying on a box of yellow cake mix) cuts way down on prep time. On the other hand, an easy upgrade (whipping the cream by hand, with a few tablespoons of sugar) gives the finished product a distinctly from-scratch taste. Use a serrated knife to cut clean slices from the two-tier strawberry shortcake, and in high summer, feel free to toss in raspberries or blueberries. The real beauty, though? You soak the strawberries in sugar before layering the cake, fruit, and cream, so even mid-winter, less-than-perfect berries shine.
