Turn on your oven to 350°F and prepare a baking tray with parchment paper to stop the cookies from sticking.
02 -
Grab a bowl and combine the flour, salt, baking soda, and baking powder. Give it a good stir and set it aside.
03 -
Whip your butter together with the sugar until creamy, fluffy, and pale. A mixer works best, and it’ll take about 3-4 minutes.
04 -
Beat in the egg and vanilla until the mixture turns smooth with no lumps left.
05 -
Slowly add the dry mix to the butter mixture, stirring gently until just mixed. Avoid over-stirring so the cookies stay soft.
06 -
Carefully mix in the blueberries and zest. Go ahead and add food coloring now if you want fun purple cookies, and stir until it’s blended in.
07 -
Use about a tablespoon of dough to make 1-inch balls, press them flat onto the tray, and sprinkle some coarse sugar over each for texture and shine.
08 -
Bake between 12-15 minutes until the edges turn a light golden color. The centers should look barely done so they stay chewy.
09 -
Leave the cookies on the tray for 5 minutes to set, then move them to a cooling rack. They’re ready to eat once cooled down.
