Ingredients for 3 ingredient sugar cookie recipe with egg

Three magic ingredients—butter, sugar, and egg—that create bakery-style cookies in record time.

The butter is everything here—use European-style or high-fat (82%+) butter for that rich, melt-in-your-mouth texture. Kirkland Signature or Plugrá are my go-tos because they hold up better when baked. If you only have salted butter, reduce the added salt to 1/4 teaspoon. Room temperature butter is key—press it between two sheets of parchment and microwave for 10 seconds if it’s too cold. Sugar-wise, Domino or C&H work perfectly, but if you’re feeling fancy, superfine sugar dissolves faster for a smoother dough. The egg? Pasture-raised or organic adds depth of flavor, but any large egg will work.

No butter? Coconut oil or vegan butter gets you close, but the texture won’t be quite the same—these are butter cookies through and through. Short on sugar? Maple syrup or honey (reduce by 1/4 cup) adds moisture but changes the flavor profile. The egg is non-negotiable for binding, but if you’re allergic, aquafaba (3 tbsp) or flax egg (1 tbsp ground flax + 3 tbsp water) can substitute. Pro tip: if your dough feels too sticky, chill it for 10 minutes—it firms up beautifully. And if you’re making these for a crowd, double the recipe—they disappear fast!

Butter and sugar can sit at room temperature for up to 3 days before baking (just cover tightly), but eggs should be used within 1 week of purchase. Once mixed, the dough keeps for 24 hours in the fridge—perfect for shaping ahead. Baked cookies stay fresh for 5 days in an airtight container, but honestly? They’re best eaten within 2 days. For gift-giving, bake in mini muffin tins—they’re adorable and portable. Freeze unbaked dough balls for 3 months (bake straight from frozen, add 2 extra minutes).

Step-by-step instructions for 3 ingredient sugar cookies

Here’s how to make these buttery shortbread bites—simple, foolproof, and ready in record time!

In a medium bowl, combine the 1 cup unsalted butter and 1 cup granulated white sugar. Using a hand mixer or wooden spoon, beat vigorously for 3-4 minutes until the mixture becomes pale and fluffy. You’ll see it nearly double in volume—that’s the air being incorporated, which makes these cookies tender and light.

I like to use a wooden spoon for this step if I don’t have a mixer—just work it like crazy for those extra 30 seconds. The butter should be completely smooth with no graininess. If you skipped the superfine sugar, don’t worry—the regular sugar will still work, though the texture might be slightly less delicate.

Add the 1 whole large egg to the butter-sugar mixture. Mix on medium speed for 1-2 minutes until fully combined and smooth. The dough should look like thick, creamy cookie dough—almost like a soft, spreadable frosting. If it looks too thick, let it sit at room temperature for 5 minutes while you prep your baking sheet.

Here’s the thing—room temperature ingredients are crucial. If your egg is cold, the dough might curdle slightly, but don’t panic. Just keep mixing for another 30 seconds until it smooths out. The dough should be pliable but not sticky enough to cling to your fingers.

Preheat your oven to 350°F and line a baking sheet with parchment paper. Using a small cookie scoop or tablespoon, drop 1-tablespoon sized dollops of dough onto the prepared sheet, spacing them about 2 inches apart. They won’t spread much, so you can get about 12 cookies from this recipe.

Bake for 10-12 minutes until the edges are light golden brown and the centers look just slightly underdone. They’ll continue cooking on the hot sheet after you remove them. I know it seems like they’re not done when they come out, but trust me—they firm up as they cool.

Let the cookies cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely. They’ll be soft right out of the oven but firm up as they cool. The secret to these cookies is their buttery richness and melt-in-your-mouth texture—no crunchy edges needed here!

Real talk: these cookies are best enjoyed warm. If you make them ahead, store in an airtight container for up to 3 days or freeze for 1 month. To reheat, pop them in the oven at 300°F for 2-3 minutes until soft and gooey again. Perfect with a glass of cold milk or a cup of coffee!

Pro cooking tips for great 3 ingredient sugar cookie recipe with egg

Butter Temperature Matters

The butter needs to be softened but not melted—this is non-negotiable for perfect texture. Press your butter between two sheets of parchment paper and microwave for 10-second bursts until it yields slightly when pressed with a finger.

I’ve ruined batches using cold butter that didn’t incorporate properly. European-style butter (like Plugrá) works best because it has a higher fat content, which gives these cookies that melt-in-your-mouth quality. 🧈

Mix Until Pale and Fluffy

Don’t skip the 3-4 minutes of creaming the butter and sugar—this step is what creates the air pockets that make these cookies tender. Use a hand mixer on medium-high speed or a wooden spoon if you’re mixing by hand.

The mixture should look pale and nearly doubled in volume when done. If you’re in a hurry, a stand mixer with the paddle attachment will cut this step down to 2 minutes. Pro tip: If your butter-sugar mix looks grainy, it’s not ready—keep going!

Egg Temperature Matters Too

Room-temperature eggs mix in smoothly, but if yours is straight from the fridge, the dough might curdle slightly. Just keep mixing for an extra 30 seconds—it’ll come together. The egg is what binds everything, so don’t rush this step.

If your dough feels too sticky, pop it in the fridge for 10 minutes to firm up before shaping. I’ve even made these with aquafaba (3 tbsp) in a pinch, though the texture won’t be quite the same.

Bake Time is Critical

These cookies bake fast—10-12 minutes at 350°F is the sweet spot. They’ll look underdone when you pull them out, but they firm up as they cool. If you bake them too long, they’ll dry out.

I like to set a timer and check at 10 minutes—they’re done when the edges are light golden brown. For even baking, rotate the pan halfway through if your oven has hot spots.

Shape for Perfect Results

Use a small cookie scoop or tablespoon to portion the dough—1-tablespoon dollops work perfectly. Space them 2 inches apart on the baking sheet since they won’t spread much.

If you’re feeling fancy, roll the dough into 1-inch balls for a more classic sugar cookie look. The key is not to overhandle the dough—just shape and bake!

Cool Before Enjoying

Let the cookies cool on the baking sheet for 5 minutes before transferring to a wire rack. This prevents them from cracking as they firm up. They’ll be soft right out of the oven but set into that perfect buttery shortbread texture as they cool.

Trust me, they’re even better warm with a glass of milk—but if you wait too long, they’ll still taste amazing! 💛
