Strawberry shortcake is a classic dessert that can be made healthier for a kids' birthday party. Use whole wheat flour or almond flour for the shortcake base, and sweeten it with a natural sweetener like honey or maple syrup. Top the shortcake with fresh strawberries and a dollop of whipped cream or Greek yogurt. This dessert is light, refreshing, and packed with vitamin C and antioxidants. Kids will love the combination of sweet strawberries and fluffy shortcake.
