1/2 cup (1 stick) unsalted butter, at room temperature
1/2 cup vegetable oil, such as canola or sunflower oil. I used almond oil.
1/2 cup granulated sugar, plus additional for sugaring tops
1/2 cup powdered sugar
1 large egg
2 teaspoons vanilla extract, or the seeds of 1 vanilla bean
2 cups all-purpose flour
1/2 teaspoon baking soda
1/4 teaspoon salt
1 cup powdered sugar
2 teaspoons milk
2 teaspoons light corn syrup
1⁄4 teaspoon vanilla extract
Preheat the oven to 350 degrees F. Line baking sheet with parchment paper, or foil, or grease generously with butter or cooking spray.
Using a mixer fitted with a paddle attachment, beat the butter in a large bowl on medium speed for about 1 minute. Add the vegetable oil. It may not fully incorporate with the butter, but that’s ok. Add the granulated sugar, powdered sugar, egg and vanilla, beating on medium speed until each ingredient is completely incorporated.
Stir in the flour, baking soda and salt all at once using a wooden spoon or the mixer set on low.
The dough will be soft.
Refrigerate the dough for 1 hour or freeze for 15 minutes to make it easier to handle.
Depending on how you divide the batter, this recipe can make anywhere from a dozen to two dozen cookies.
Bake for 12 to 14 minutes for larger cookies or 8 to 10 minutes for smaller cookies. Let the cookies cool on the baking sheet for at least 10 minutes before transferring to racks to cool completely. The cookies will keep for up to 3 days if stored in an airtight container.
To make them Valentine’s Day cookies, you can create Valentine’s Day icing by combining and mixing the sugar, milk, corn syrup, and vanilla extract until it is smooth and thick. Mixing in red food coloring will make the icing pink, perfect for the holiday.
