These sugar cookies start with a box of cake mix, which replaces the usual flour, sugar, and leavening with one perfectly balanced dry mix. The result is a soft, chewy cookie with a tender crumb and a classic vanilla flavor, ready in about 20 minutes from start to finish. This is a genuinely useful shortcut for busy bakers who want homemade-style cookies without measuring a dozen dry ingredients.
Ingredients
- 1 box (15.25 oz / 432 g) white or yellow cake mix
- 2 large eggs, at room temperature
- 1/3 cup (80 ml) vegetable oil (or melted butter, cooled)
- Optional: 1 teaspoon vanilla extract (if your cake mix is not vanilla-flavored)
- Optional: 1/4 cup (50 g) granulated sugar, for rolling
Instructions
- Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone baking mats.
- In a large bowl, combine the cake mix, eggs, and oil. If using vanilla extract, add it now. Stir with a sturdy spoon or spatula until a soft, cohesive dough forms. It will be slightly sticky but should hold together when pressed.
- If you want sparkly, crackly cookies, place the granulated sugar in a small bowl. Scoop tablespoon-sized portions of dough (about 1.5 tablespoons / 20 g each) and roll them into balls. Roll each ball in the sugar to coat evenly.
- Place the dough balls on the prepared baking sheets, spacing them about 2 inches (5 cm) apart. Do not flatten them; they will spread as they bake.
- Bake one sheet at a time on the center rack for 9–11 minutes, or until the edges are set and just starting to turn golden. The centers will look slightly underdone—that’s perfect. Do not overbake, or the cookies will be dry.
- Let the cookies cool on the baking sheet for 5 minutes. They will continue to set as they cool. Then transfer them to a wire rack to cool completely.
Tips
- Don’t overmix: Stir just until the dry mix is moistened. Overmixing develops gluten and makes cookies tough.
- Chill if sticky: If the dough is too sticky to roll, refrigerate it for 20–30 minutes. This also helps prevent excessive spreading.
- Butter vs. oil: Oil yields a softer, chewier cookie. Melted butter gives a slightly richer flavor and a bit more spread. Both work well; just use what you have.
- Check your cake mix size: Boxes vary from 15 to 16 ounces (425–455 g). If using a larger box, add an extra tablespoon of oil and one extra egg white to keep the dough from being too dry.
Serving Suggestions
These cookies are wonderful on their own with a glass of milk or a cup of coffee. For a festive touch, sandwich two cookies with buttercream frosting, or dip half of each cooled cookie in melted chocolate and sprinkle with colorful jimmies. They also make great ice cream sandwich cookies—use slightly underbaked, softer cookies for best results.
Variations
- Lemon Sugar Cookies: Use lemon cake mix, replace the oil with melted butter, and add 1 tablespoon lemon zest. Roll in sugar mixed with a little lemon zest.
- Chocolate Chip: Use white or yellow cake mix and fold in 3/4 cup (130 g) mini chocolate chips before scooping.
- Red Velvet: Use red velvet cake mix and fold in 1/2 cup (85 g) white chocolate chips. These are perfect for Valentine’s Day.
- Spiced: Use spice cake mix and add 1/2 teaspoon cinnamon and a pinch of nutmeg. Roll in cinnamon-sugar.
- Gluten-Free: Use a gluten-free yellow or white cake mix. The rest of the recipe stays the same; just check that your mix contains a binder like xanthan gum.
Storage and Reheating
Store baked cookies in an airtight container at room temperature for up to 5 days. To keep them soft, add a slice of plain bread to the container—it releases moisture and the cookies stay tender. For longer storage, freeze baked cookies in a single layer in a freezer-safe bag for up to 3 months. Thaw at room temperature for 30 minutes. To refresh, warm a cookie in the microwave for 8–10 seconds, or in a 300°F (150°C) oven for 3–4 minutes. You can also freeze the unbaked dough balls for up to 3 months; bake directly from frozen, adding 2–3 minutes to the baking time.
Frequently Asked Questions
Can I use butter instead of oil? Yes. Use 1/3 cup (75 g) melted and slightly cooled unsalted butter. The cookies will be a bit flatter and richer in flavor. If using salted butter, reduce any added salt in the recipe.
Why are my cookies spreading too much? The most common causes are warm dough, a greasy baking sheet, or an oven that runs cool. Chill the dough for 20 minutes, use parchment paper, and verify your oven temperature with an oven thermometer.
Can I make these without eggs? Yes, you can substitute each egg with 1/4 cup (60 g) unsweetened applesauce or a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water, let sit for 5 minutes). The cookies will be slightly softer and a bit more cake-like.
How do I make them chewier? Use oil instead of butter, remove them from the oven when the edges are just set (around 9 minutes), and let them cool completely on the baking sheet. Also, underbaking slightly is the key.
Can I use a different flavor of cake mix? Absolutely. Any flavor works—chocolate, strawberry, funfetti, or even carrot cake. Just adjust the add-ins to complement the flavor. For chocolate cake mix, consider adding 1/2 cup (85 g) chocolate chips or chopped nuts.
Do I need to refrigerate the dough? Not for immediate baking, but chilling for 30 minutes makes the dough easier to handle and helps the cookies keep their shape better. If you want thicker cookies, chilling is recommended.
