-Flour, Baking Powder & Cornstarch -Oil -Egg -Sugar and Vanilla -Butter -Raspberry Jam or Preserves
Cream the butter and sugar in a large bowl, then add the oil, egg, and vanilla and mix well to combine.
Add the flour, cornstarch, baking powder and salt to the wet ingredients and mix well. Chill the dough for at least 30 minutes.
Once dough has chilled in the fridge, roll it into small 1-inch balls.
Using a measuring spoon (or your thumb!) gently press into each cookie dough ball to form an indentation.
Fill each cookie with the raspberry preserves, then bake for 8-10 minutes. Allow the cookies to cool on the pan for 5 minutes before transferring to a cooling rack.
Chilling the dough not only makes it easier to work with and roll into balls, but it will help prevent the cookies from spreading during baking.
