In a bowl, whisk together powdered sugar and milk to your desired consistency. (Use less liquid for a thicker icing; add more liquid for a thinner glaze.)
Optional: Add vanilla extract for a vanilla icing, or add any other flavoring you’d like.
Use a spoon to pour or drizzle icing over cookies, cakes &pastries while they’re still warm (but not too hot, or the icing will melt). Allow to set at room temperature—the icing will harden as the baked goods cool.
Yield: ~½ cup icing or glaze. (Enough for ~40 cookies, 1 Bundt cake, 12 cinnamon rolls, 8-10 scones.)
Storage: Cover powdered sugar icing or glaze and store at room temperature for up to 3 days.
How to Make Frosting with Powdered Sugar
In a large bowl, beat softened butter (and/or cream cheese) with a hand mixer until smooth & creamy, for about 2 minutes.
Add powdered sugar and milk (if needed) and beat for 1-2 minutes, until fluffy.
Optional: Beat in vanilla extract or any flavoring you’d like. Or beat in a drop of food coloring to make different frosting colors.
Spread or pipe frosting onto completely cooled cookies, brownies, or cupcakes. Allow to set in the fridge for about an hour.
Yields: ~⅔ cup buttercream frosting. (Enough for 12-16 cupcakes or a pan of brownies.)
Storage: Keep buttercream in an airtight container or sealed piping bag at room temperature for 1-2 days, or store in the fridge for up to a week.
