I actually was hoping for a soft, thick sugar cookie, but I got a thin and crispy one. THe flavor was still amazing, and I still did like the crispyness. I may come out with a thick, soft, chewy, lemon cookie in the near future....
Preheat oven to 350 degrees. Grease baking sheets.
Combine flour, baking soda, and baking powder in a small mixing bowl. Set aside. Combine butter and sugar and cream. Add egg, vanilla, and lemon vest, and beat until smooth. Add flour mixture gradually til soft dough forms.
Drop dough by rounded teaspoon onto a greased baking sheet. Bake until edges turn brown and cookie appears puffy. About 12 minutes. Let sit about 3 minutes to set, and transfer to wire rack to cool completely.
For glaze combine powdered sugar, milk, water, and vanilla. If glaze is too thick, add some water til thin glaze. Pour 2 teaspoons of glaze over each cooled cookie. Sprinkle with sprinkles. (optional, and glaze is optional as well).
