Ingredients for shortbread cookie recipe no eggs

Five simple ingredients deliver the same buttery crunch and vanilla sweetness of classic shortbread—without eggs.

The unsalted butter is non-negotiable here—use European-style or Plugrá for superior flavor and lower water content. Store it in the fridge to maintain firmness, and let it sit at room temperature for exactly 30 minutes before cubing. For the all-purpose flour, King Arthur or Bob's Red Mill brands yield the best texture; avoid pre-sifted versions. The aquafaba should be fresh—save the liquid from a can of chickpeas (like Goya or Chickpeas in Water) and whisk it vigorously until frothy. This substitution is the secret to achieving the same structure as eggs without compromising the delicate crumb.

No vanilla extract? Vanilla bean paste or seeds work beautifully—just add the seeds directly to the dough. Short on sugar? Coconut sugar or maple syrup can replace granulated sugar, though texture may vary slightly. The cornstarch is optional but recommended for an extra tender bite; if omitted, increase flour by 1 tbsp. For a lemon twist, zest 1 lemon and add it to the dough. The flaky sea salt (like Maldon) is purely for finishing—sprinkle it lightly over the tops before baking for a sophisticated touch.

Store the dough in an airtight container in the fridge for up to 5 days, or freeze it for 3 months for freshly baked cookies anytime. Once baked, keep the cookies in a tin or airtight container at room temperature for up to 1 week to maintain their crisp edges. For a restaurant-quality presentation, pack them in layers separated by parchment paper. These cookies reheat beautifully—pop them in a 350°F oven for 3-5 minutes to restore their buttery crunch.

Step-by-step instructions for eggless vanilla shortbread cookies

Here's how to craft buttery, crunchy shortbread without eggs—using aquafaba for perfect texture.

In a stand mixer fitted with the whisk attachment, combine the 0.25 cup aquafaba and 1 tsp pure vanilla extract. Whip on high speed for 4-5 minutes until glossy and holding stiff peaks when the whisk is lifted. You're looking for a texture similar to meringue—this will bind your dough just like eggs would.

I like to stop the mixer occasionally to scrape down the sides with a silicone spatula. This ensures even aeration throughout. If the aquafaba doesn't stiffen after 5 minutes, add 1 tbsp cornstarch mixed with 1 tsp water and whip for another 2 minutes. The aquafaba should hold its shape when you turn the bowl upside down.

While the aquafaba whips, place the 1 cup unsalted butter (cold, cubed) in the bowl of a stand mixer fitted with the paddle attachment. Beat on medium speed for 1 minute to soften slightly. Add the 0.5 cup granulated sugar and 0.5 tsp diamond crystal kosher salt, then beat on medium-high speed for 3-4 minutes until light and fluffy.

The mixture should nearly double in volume and become pale in color. This creaming process incorporates air, which creates those signature shortbread cracks and tender crumb. Don't rush this step—under-creamed butter leads to dense cookies. If the butter melts before reaching this stage, chill the bowl in the freezer for 10 minutes while you finish whipping the aquafaba.

Add the stiff aquafaba to the butter mixture in 2 additions, mixing on low speed after each until fully incorporated. Scrape down the sides of the bowl as needed. In a separate bowl, whisk together the 2 cups all-purpose flour (sifted) and 1 tbsp cornstarch. Gradually add the dry ingredients to the wet, mixing on low speed just until combined.

Here's where it gets tricky—I like to press the dough together gently with my hands to ensure even distribution of the flour. The dough should hold together when pressed but still be slightly crumbly. If it's too sticky, add 1-2 tablespoons more flour; if too dry, add 1 teaspoon aquafaba. Wrap the dough in plastic wrap and chill for at least 1 hour (or up to 24 hours) in the refrigerator.

Preheat your oven to 350°F. Line two baking sheets with parchment paper. On a lightly floured surface, roll the chilled dough into a ½-inch thick rectangle. Cut into 1-inch squares using a sharp knife or cookie cutter. Place cookies 2 inches apart on the prepared baking sheets.

Bake for 12-15 minutes until the edges are golden brown and the centers look just slightly underbaked. The cookies will continue firming up as they cool. Watch closely after 10 minutes—shortbread burns easily. When done, remove from oven and sprinkle immediately with 1 tsp flaky sea salt and 1 tsp vanilla bean seeds (if using). Let cool on the baking sheet for 5 minutes before transferring to a wire rack.

For the best texture, let the cookies cool completely on the rack for at least 1 hour before storing. This resting period allows the flavors to meld and the crumb to set properly. The cookies should be crisp around the edges with a tender, melt-in-your-mouth center.

Store in an airtight container at room temperature for up to 5 days, or freeze for up to 3 months. For extra crunch, serve with a cup of tea or coffee—these cookies pair beautifully with Earl Grey or chai. The vanilla and salt combination creates a perfect balance of sweetness and sophistication without any eggy aftertaste.

Storing and reheating this dish

Room Temperature Storage

Keep your egg-free shortbread cookies at their best by storing them in an airtight container at room temperature for up to 5 days. The crisp edges and tender centers develop fully after 24 hours, so freshly baked cookies taste even better the next day.

I like using glass containers with silicone seals—they keep the cookies from drying out while maintaining that perfect crunch. 🌟

Freezer Preservation

For long-term storage, freeze the cookies in a single layer on a baking sheet for 1 hour before transferring them to a freezer-safe bag or airtight container.

This prevents them from sticking together. They’ll stay fresh for up to 3 months, and you can reheat them directly from frozen using the method below. 🧊

Reheating for Crunch

To restore that buttery crunch, place cookies on a baking sheet and warm them in a 350°F oven for 3-5 minutes. For a quicker fix, use the air fryer at 325°F for 2 minutes—this method keeps the edges crisp while warming the center.

Avoid microwaving, as it can make the cookies rubbery. 🔥

Reviving Dried Edges

If your cookies lose their crispness, place them in a paper bag with a slice of bread for 10-15 minutes. The bread’s moisture will help restore the texture without making the cookies soggy. For extra crunch, sprinkle a pinch of flaky sea salt on top before reheating. ✨

Dough Storage Tips

Unused dough can be stored in the fridge for up to 5 days or the freezer for 3 months. Wrap it tightly in plastic wrap or place it in an airtight container to prevent drying.

When ready to bake, let the dough sit at room temperature for 30 minutes before rolling to avoid cracking. 💛

Packaging for Gifts

For gift-giving, layer cookies between parchment paper in a rigid box or tin. Add a ribbon and a handwritten note for a thoughtful touch. These cookies travel well and maintain their texture for 3-4 days at room temperature. 🎁
