Made with the usual sugar cookie ingredients, it's the special ratio that turns them into my dreamy Soft Sugar Cookies!
In a large bowl, cream together the butter and the sugar until pale and fluffy.
Next, add the eggs and vanilla and mix until just combined.
Stir in salt, baking powder and flour and mix until a dough is formed. Cover the dough with plastic wrap and chill for 1 hour*. At this point the dough can also be frozen to be baked off at a later date.
Pre-heat your oven to 350°F (180°C). Line 2 cookie sheets with parchment paper and set aside.
After 1 hour, roll the cookies into 1 tablespoon balls. Place the cookies about 2 inches apart on the prepared cookie sheet and press down to create a 1/4 inch thick cookie.
Bake for 8-10 minutes or until slightly golden. Remove from the oven and allow to cool completely on a wire rack.
While the cookies are baking make the icing: Using a whisk, combine the powdered sugar, butter, milk and vanilla until you have a smooth thick icing. Color the icing with a few drops of food coloring then mix until even in color.
Using a small offset spatula frost the cookies then scatter over sprinkles. Allow to set for about 30 minutes.
Once set, cover and store the cookies in an airtight container for up to 3 days.
*Chilling: don't skip this step! Chilling helps the cookies retain shape, and further helps with flavor and texture. In fact, chill for longer if you can!
