Ingredients Breakdown

Let’s take a closer look at what makes these cookies so uniquely delicious:

Wet Ingredients:

  • Granulated sugar (½ cup + extra for rolling)
    Adds sweetness and a light crunch on the outside.
  • Powdered sugar (½ cup)
    Creates a tender, melt-in-your-mouth texture.
  • Egg (1 large)
    Binds the dough and adds richness.
  • Butter (½ cup, softened)
    Brings classic buttery flavor and helps with spread.
  • Vegetable oil (½ cup)
    Keeps the cookies soft and gives them a delicate crumb.
  • Vanilla extract (½ tsp)
    Adds warmth and depth.

Dry Ingredients:

  • All-purpose flour (2 cups)
    Provides structure and balance.
  • Baking soda (½ tsp)
    Helps the cookies rise and spread.
  • Salt (½ tsp)
    Enhances flavor and balances sweetness.
  • Cream of tartar (½ tsp)
    Adds a subtle tang and helps create a soft, chewy texture.

Optional: Add a pinch of nutmeg or lemon zest for a twist on the classic flavor.

Equipment Needed

  • Stand mixer or hand mixer
  • Mixing bowls
  • Measuring cups and spoons
  • Cookie sheets
  • Parchment paper
  • Cookie scoop or tablespoon
  • Cooling racks
  • Oven

Step-by-Step Instructions

Step 1: Cream the Wet Ingredients

In a stand mixer or large bowl:

  • Combine ½ cup granulated sugar, ½ cup powdered sugar, 1 egg, ½ cup softened butter, ½ cup vegetable oil, and ½ tsp vanilla extract.

Mix on medium speed until smooth and fully incorporated.

Step 2: Add the Dry Ingredients

In a separate bowl:

  • Whisk together 2 cups flour, ½ tsp baking soda, ½ tsp salt, and ½ tsp cream of tartar.

Gradually add the dry mixture to the wet ingredients.

Mix until a soft dough forms, scraping down the sides as needed.

Step 3: Chill the Dough

Cover the dough and chill:

  • Overnight in the refrigerator for best results
  • Or at least 1 hour in the freezer for a quicker option

Chilling helps the cookies hold their shape and enhances flavor.

Step 4: Shape and Roll

Preheat oven to 350°F (175°C).

Line cookie sheets with parchment paper.

Scoop dough into 1–2 tablespoon-sized balls.

Roll each ball in granulated sugar.

Place on cookie sheet, spacing 1½–2 inches apart.

Flatten each ball to about ½ inch thick using:

  • A cookie press
  • The bottom of a glass
  • A fork or your palm

Step 5: Bake

Bake for 10–15 minutes, until:

  • Edges are lightly golden
  • Centers are set but still soft

Let cool on the baking sheet for a few minutes before transferring to a wire rack.
