Preheat a large nonstick pan or electric griddle to medium heat. Whip cream in a stand mixer or with an electric hand mixer and set aside. Whisk together pancake mix, egg, and milk until smooth. Pour the batter into 4-5 inch circles and cook for about 3-4 minutes on each side, until golden brown and firm. While the pancakes are cooking, slice strawberries and set aside. Stack cooked pancakes on plates and top with strawberries and whipped cream.
*2 cups of store-bought whipped topping can be substituted for homemade whipped cream.
