Sweet, zesty, and full of juicy berries, these lemon cake mix cookies are soft, chewy, and totally irresistible. They're made with cake mix for a super easy shortcut, and the cream cheese keeps them soft and fluffy. Plus, that glaze? You’ll be licking the spoon.
Get prepped: Line a baking sheet with parchment paper and set aside. Preheat oven to 350°F.
Make the cookie dough: Cream the ½ cup butter and 8 ounces cream cheese together using a hand or stand mixer for about a minute.
Mix in the 1 tablespoon lemon zest1 large egg, and 1 teaspoon vanilla extract.
Add the13.25 oz lemon cake mix and mix until combined.

Use a rubber spatula to scrape down the sides of the bowl if needed.
Fold in the ½ cup white chocolate chips, if using, then gently fold in the 1 cup fresh blueberries. Try not to burst them or the dough will turn blue-green.
Chill the dough: Use a cookie scoop to portion the dough onto a separate cookie sheet. Don’t worry about spacing them out. Cover with plastic wrap and chill in the fridge for 1 hour.
Bake: Transfer the chilled dough scoops to your prepared baking sheet, leaving space between each one. Gently press down each scoop to flatten slightly. These cookies don’t spread much.
Bake for 19 minutes or until just lightly golden around the edges.
Cool: Cool on the pan for 5 minutes, then transfer to a wire rack to cool completely.
Glaze: Once cookies are at room temp, mix 1 cup powdered sugar with 1½ to 2 tablespoons water. Stir until smooth. If too thick, add a little more water.
For a thinner drizzle, use a spoon. For more control, spoon the glaze into a small zip-top bag, snip a tiny corner, and squeeze to pipe it on.
Notes
You can swap in yellow or vanilla cake mix if that’s what you have. Add 1–2 tablespoons fresh lemon juice to bump up the lemon flavor.
Chilling the dough helps prevent spreading. If you're skipping the chill, space the cookies out more before baking.
For extra lemon zing, use lemon juice instead of water in the glaze.
