To prepare a strawberry crescent roll shortcake recipe, first you need to gather your ingredients. First, you'll need the following ingredients: 14 cup (60 milliliters) sugar, 1 tablespoon (2.5 ml) vanilla extract, and 1 teaspoon (0.5 g) salt. Then, mix the ingredients together until the sugar dissolves. Next, add the vanilla to the mixture and mix until it's completely dissolved. Finally, pour the batter into the prepared pan and bake for 20 to 25 minutes. Remove the pan from the oven and allow the cake to cool for 10 to 15 minutes before serving.
