Ingredients

• 1 cup powdered sugar (confectioners’ sugar)
• 2 tablespoons milk (whole or 2% for best texture)
• 1 teaspoon vanilla extract (or almond extract for a nutty flavor)
• 1 teaspoon lemon juice (freshly squeezed to add brightness)
• Optional: Food coloring drops or zest of lemon/orange for flavor variations

Equipment

• Mixing bowl (medium size)
• Whisk or fork (for mixing)
• Measuring cups and spoons
• Spoon or small spatula (for spreading or drizzling)
• Cooling rack (to place cookies while icing sets)
• Optional: Piping bag or plastic sandwich bag (for precise drizzle)

Instructions

1. Combine powdered sugar and milk. In your mixing bowl, sift the powdered sugar to avoid lumps. Add 2 tablespoons of milk gradually while whisking until smooth and glossy.
2. Add vanilla extract and lemon juice. Stir in 1 teaspoon vanilla extract and 1 teaspoon lemon juice. These add depth and a subtle tang that balances the sweetness.
3. Adjust consistency. If the icing is too thick, add milk a few drops at a time until it reaches a pourable but slightly thick glaze consistency. If too thin, add a pinch more powdered sugar.
4. Color or flavor (optional). Add a few drops of food coloring or a teaspoon of citrus zest for a fun twist. Mix well.
5. Apply the icing to cooled thumbprint cookies. Using a spoon, spatula, or piping bag, gently drizzle or spread the icing over the jam centers or around the edges. Avoid icing warm cookies to prevent melting.
6. Let the icing set. Place the iced cookies on a cooling rack and allow the glaze to harden at room temperature for about 30-60 minutes. The icing will dry to a shiny, firm finish.
7. Store or serve. Once set, your cookies are ready to enjoy! Store them in an airtight container to keep the icing crisp.

Tips & Variations

Pro tip: For a smoother glaze, always sift your powdered sugar before mixing.

If you want a thicker icing for piping designs, reduce the milk slightly. For a thinner glaze suitable for drizzling, add a bit more milk.

Try swapping vanilla extract for almond or orange extract to match your jam flavor, such as apricot or raspberry.

For a festive look, add colored sugar or edible glitter before the icing sets.
