Begin by taking a large mixing bowl. Add the vegetable oil, melted butter, eggs, vanilla extract, salt, baking powder, and 1 cup of powdered confectioners’ sugar. Whisk or use an electric mixer to blend until smooth.

Gradually add in the all-purpose flour while mixing continuously until the dough is smooth and fully incorporated.

Cover the bowl with plastic wrap and refrigerate the dough for at least 1 hour.

Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper.

Shape the chilled dough into ropes about 4 inches long and ½ inch in diameter, then connect the ends to form a donut shape. Place them on the baking sheets, leaving space between each cookie.

Bake the cookies for 16-18 minutes until the tops are golden and slightly firm.

Let the cookies cool on baking sheets for a few minutes before transferring to a wire rack to cool completely.

For the icing, mix ½ cup of powdered sugar with 1 tablespoon of milk and 2 teaspoons of corn syrup in two small bowls. Add food coloring to each for desired colors.

Once the cookies are cool, dip the tops in icing or spread with a spoon. Immediately add festive sprinkles while the icing is still wet.

Allow the icing to harden before enjoying or storing.
