Single Serving Sugar Cookie
This single serving sugar cookie bakes up with crispy golden edges and a soft, chewy center — all in under 20 minutes using just one bowl and a spoon. No stand mixer, no chilling time, no leftover temptation. Just a warm, buttery, perfectly portioned treat whenever that sweet craving strikes.
Equipment
- Small mixing bowl
- Measuring cups and spoons
- Rubber spatula or wooden spoon
- Small baking sheet - Quarter sheet pan recommended
- Parchment paper or silicone baking mat
- Wire cooling rack
Ingredients
- 2 tablespoons unsalted butter - 28g, softened to room temperature
- 3 tablespoons granulated sugar - 38g, plus 1 teaspoon reserved for rolling
- 1 large egg yolk - white reserved for another use
- 1/4 teaspoon vanilla extract
- 1/3 cup all-purpose flour - 42g, measured using spoon-and-level method
- 1/8 teaspoon baking soda
- 1/8 teaspoon salt
Optional Add-ins
- 2 tablespoons rainbow sprinkles - optional; nonpareils recommended
Instructions
- Preheat your oven to 350°F (177°C) and position the rack in the center. Line a small baking sheet with parchment paper or a silicone baking mat.
- In a small mixing bowl, use a rubber spatula to press and mix the softened butter and 3 tablespoons of granulated sugar together vigorously for 1–2 minutes until light, fluffy, and pale.
- Add the egg yolk and vanilla extract to the butter-sugar mixture and mix for 30–45 seconds until completely smooth, glossy, and streak-free.
- Add the flour, baking soda, and salt to the bowl and stir gently just until no flour streaks remain, about 15–20 strokes — do not overmix.
- If using sprinkles, fold them in with a few gentle strokes, being careful not to overmix so the colors don't bleed into the dough.
- Roll the dough into a smooth ball, coat it completely in the reserved teaspoon of granulated sugar, place it on the prepared baking sheet, and press down gently to about ½ inch thick.
- Bake for 14–16 minutes, until the edges are golden brown and set while the center still looks slightly underdone — it will continue to cook as it cools.
- Let the cookie rest on the pan for 5 minutes to firm up, then transfer to a wire rack and cool another 5–10 minutes before enjoying.
Notes
- Room temperature butter: Butter should feel cool but yield easily to pressure. Too soft or melted butter causes the cookie to spread too thin and turn greasy.
- Measure flour correctly: Use the spoon-and-level method — spoon flour into the cup then level off. Scooping directly packs in too much flour, resulting in a dry, cakey cookie.
- Don't skip sugar rolling: Rolling the dough in sugar before baking creates a sparkly crust and a satisfying textural contrast with the soft interior.
- Watch the edges, not the clock: Oven temperatures vary. Pull the cookie when edges are golden and set but the center still looks slightly underdone for that chewy middle.
- Salted butter substitute: You can use salted butter — just reduce or omit the added salt to avoid an overly salty cookie.
- Baking soda freshness: Test your baking soda by dropping a pinch into vinegar. If it doesn't fizz vigorously, it's time for a new box.
- Flavor variations: Swap vanilla extract for 1/8 tsp almond extract for a classic bakery flavor, or add 1/4 tsp lemon zest for a citrusy twist.
- Mix-in swaps: Replace sprinkles with 2 tablespoons of mini chocolate chips, white chocolate chips, or a pinch of cinnamon in the dough.
- Storage: Store in an airtight container at room temperature for up to 3 days, or freeze wrapped tightly for up to 2 months.
- Make-ahead dough: Refrigerate shaped, sugar-rolled dough for up to 2 days, or freeze for up to 3 months and bake from frozen, adding 2–3 minutes to the baking time.
