Step 1: heat the oven

Preheat your oven to 350°F/175°C and line a baking sheet with parchment paper. To really get that citrus flavor, we want to release the oil from the zest into the sugar.

Step 2: combine ingredients

In a large bowl, combine the melted butter with the sugar – whisk until well combined.

Step 3: add wet ingredients

Add the eggs, lemon juice, lemon extract, and vanilla to the batter. Stir well.

Step 4: add ingredients to cookie dough

Add to the cookie dough mixture. Mix until just combined.

Step 5: add blueberry

Gently mix in the frozen blueberries. Be careful not to mix here over. Try whole blueberries.

Step 6: shape the cookies

Scoop cookie dough into cookie dough balls and arrange on a quarter sheet pan. Cover with plastic wrap and refrigerate the dough for 30-60 minutes.

Step 7: bake the cookies

Once the dough is chilled, bake the cookies on a parchment-lined sheet pan at 350° for 8-10 minutes.

Step 8: drizzle the cookies

While the cookies are baking, make the lemon glaze. Drizzle the baked cookies with the lemon glaze.

Step 9: store cookies

Allow the glaze to set until dry. Store baked cookies in an airtight container for 1-2 days.

Make sure your blueberries are nice and frozen before adding them to the cookie dough.
