Made these last week and practically had to lock them up to keep Buck out of them.
1 box lemon cake mix, 1/2 cup oil, 2 eggs, 1 cup white baking chips, 1 teaspoon freshly grated lemon rind. Mix all together and drop onto ungreased cookie sheet. Bake in preheated 350F oven for 12 to 14 minutes. Makes about 3 dozen 3-inch cookies.
The lemon rind is the key. Since you want "lemony" cookies, you might want to add more rind.
