In a large mixing bowl, combine the strawberry cake mix, eggs, oil, and vanilla together and mix well (you can use a fork or a hand mixer).
Line a baking sheet with parchment paper and create 1 tablespoon cookie dough balls with a cookie scoop. Place the cookies about 2” apart on the baking sheet.
Bake for 10 minutes - or until the edges start to brown. Do not over bake.
Remove from the oven and let the cookies cool on the baking sheet while you make the glaze.
To make the glaze, blend strawberries and lemon juice together in a food processor or blender. Blend the strawberries to a puree, or leave larger chunks.
Add strawberry mixture to powdered sugar and mix until smooth (if the glaze is too thin, add powdered sugar. If it’s too thick, add more lemon juice or water).
Transfer cookies to a cooling rack and spoon glaze on top of cookies.
Once cooled, sprinkle with powdered sugar (optional).
Keep an eye on your cookies in the oven. You do not want to overbake these! Once they start to lightly brown on top, pull them out of the oven. They puff up nicely and taste best when they are chewy and soft.
You can sprinkle with powdered sugar before or after you add the glaze. Either way works.
