The uncomplicated and delicious sugar cookie gets a fresh, new flavour profile, and an upgrade in this Lilac Sugar Cookies recipe. A classic sugar cookie base is baked with lilac infused sugar, lilac syrup, and lilac petals. Topped with a simple glaze and sprinkled with more lilac flowers, these cookies are a great early summer treat!
Preheat oven to 350 degrees. Line a baking sheet with parchment paper or a silicone baking mat. Set aside.
In a large bowl, use a mixer to beat together the butter and sugar until creamy and light yellow in colour. (About 4-5 minutes.)
Add the eggs one at a time and beat into the butter and sugar mixture.
Beat in the lilac syrup.
Sift in the flour, salt, and baking powder. Beat into the wet mixture until just combined.
Add in the lilac petals and stir into the cookie dough to incorporate.
Portion the cookie dough into heaping tablespoons. Roll into a ball and place onto the prepared baking sheet.
Press down on each ball until ball is flattened to just over 1/4 inch thick. (I used the bottom of a drinking glass.)
Bake for 10 minutes. Remove from oven and allow to cool for 2-3 minutes before transferring to a wire cooling rack to finish cooling.
Once completely cooled, stir the lilac syrup and purple food colouring into the confectioner's sugar until a thin, smooth frosting is formed.
Lay the cookies face up onto a wire cooling rack with a baking sheet underneath to catch any dripping frosting.
Drizzle the frosting over the cookies working in a zigzag pattern. Immediately top the cookies with extra lilac petals before the frosting hardens. Once hardened and dry, pack the cookies into a cookie jar or tin.
