Lemon Sandwich Cookies with Curd

The first time I attempted vegan lemon curd, I stood over that saucepan with my heart in my throat, convinced it would never thicken without eggs. But when that glossy, sunshine-yellow mixture suddenly coated the back of my spoon, I actually did a little victory dance right there in my kitchen. These sandwich cookies became an instant staple in my baking rotation after that day.

I brought a batch to my book club last spring, and they disappeared before anyone even touched the savory snacks. One friend who is notoriously suspicious of vegan baking took one bite and immediately asked for the recipe. Now they are the most requested treat at every gathering.

Ingredients

• Gluten-free all-purpose flour blend: The backbone of these delicate cookies, providing structure without the heavy texture of some gluten-free flours
• Almond flour: Adds a subtle nuttiness and tender crumb that makes these feel indulgent despite being vegan
• Cornstarch: The secret weapon for keeping these cookies light and melt-in-your-mouth delicate
• Solid coconut oil: Creates that perfect shortbread texture, but make sure it is firm, not melted, or your dough will be too sticky
• Organic cane sugar: Sweetens while letting the bright lemon flavor shine through without overwhelming
• Lemon zest: Do not skip this, those little flecks of zest are where all the fragrant lemon oil lives
• Fine sea salt: Balances the sweetness and makes all the flavors pop
• Baking soda: Just enough to give these cookies a subtle lift without making them cakey
• Unsweetened applesauce: The perfect egg replacement that adds moisture without altering the flavor
• Lemon juice: Brightens the dough and complements the zest beautifully
• Vanilla extract: Rounds out all the sharp citrus notes with warmth
• Fresh lemon juice: Use freshly squeezed, bottled juice lacks that vibrant zing we want
• Coconut cream: Creates that silky, luxurious texture in the curd that mimics traditional egg-based versions
• Turmeric: Just a pinch gives the curd that gorgeous yellow color without changing the taste

Instructions

Whisk up your sunshine curd first:

Combine the lemon juice, zest, sugar, cornstarch, coconut cream, turmeric, and salt in your saucepan, whisking until the cornstarch disappears completely.

Cook it to glossy perfection:

Set it over medium heat and whisk without stopping, watching in amazement as it transforms from thin to gorgeously thick in just 3 to 4 minutes.

Let it cool and set:

Transfer that beautiful yellow mixture to a bowl and let it cool completely, then pop it in the fridge to thicken even more while you make the cookies.

Cream your coconut oil and sugar:

Beat them together until they are light and fluffy, which will take about 2 minutes with an electric mixer.

Add the wet ingredients:

Pour in the applesauce, lemon zest, lemon juice, and vanilla, mixing until everything is well combined.

Whisk the dry ingredients:

In a separate bowl, combine the gluten-free flour, almond flour, cornstarch, salt, and baking soda until they are evenly distributed.

Bring the dough together:

Gradually add the dry ingredients to the wet, mixing gently until a soft dough forms that holds together when you pinch it.

Chill for easier rolling:

Divide the dough in half, shape each into a disc, wrap them in parchment, and let them rest in the fridge for 30 minutes.

Get your oven ready:

Preheat to 350°F and line two baking sheets with parchment paper.

Roll and cut your cookies:

On a lightly floured surface, roll the dough to 1/4 inch thickness and cut out 2 inch rounds.

Bake until just golden:

Arrange them on your prepared baking sheets and bake for 10 to 12 minutes until the edges are barely golden.

Cool completely:

Let them rest on the baking sheets for 5 minutes, then transfer to a wire rack to cool completely.

Assemble your sandwiches:

Spread 1 to 2 teaspoons of that luscious curd on the flat side of half the cookies, then top with the remaining cookies.

Add a finishing touch:

Dust with powdered sugar if you are feeling fancy, which I almost always am.

Last summer my neighbor came over unexpectedly when I had a fresh batch cooling on the counter. She ended up staying for two hours, drinking tea and eating three of these cookies while we talked about everything and nothing. Sometimes food is just the excuse we need to slow down and connect.

Making These Ahead

I have learned through happy accident that the cookie dough actually freezes beautifully. I often double the batch, wrap the dough discs well, and stash them in the freezer for those days when I need fresh baked cookies but zero ambition to start from scratch.

Getting The Texture Right

The secret to that perfect snap when you bite down is rolling the dough to exactly 1/4 inch thickness. Too thin and they will be fragile, too thick and they lose that delicate shortbread quality. I use two chopsticks as guides on either side of my dough to keep it consistent.

Serving Suggestions

These cookies are remarkably versatile despite their elegant appearance. They hold their own alongside espresso after dinner, but are just as happy on a casual afternoon snack plate.

• Earl Grey tea is the classic pairing for a reason, the bergamot loves the lemon
• A cold glass of almond milk makes for a surprisingly comforting afternoon snack
• They are elegant enough to serve on a tiered tray at your next garden party

There is something deeply satisfying about turning simple plant-based ingredients into something that feels so special and indulgent. Happy baking, friends.

Recipe FAQs

→ How long does the lemon curd need to chill?

The lemon curd should cool completely at room temperature after cooking, then refrigerate for at least 30 minutes to achieve proper thickness for spreading.

→ Can I make the dough ahead of time?

Yes, the dough discs can be wrapped in parchment and refrigerated for up to 24 hours before rolling and baking. Let soften slightly at room temperature before rolling.

→ What's the best way to store these cookies?

Store assembled sandwiches in an airtight container in the refrigerator for up to 3 days. The cool temperature helps maintain the curd's texture and prevents softening.

→ Can I freeze these sandwich cookies?

Freeze unbaked cookie dough discs for up to 3 months, thawing overnight before rolling. Assembled cookies don't freeze well due to the curd filling.

→ What can I substitute for coconut oil?

Solid vegan butter or cold palm shortening can replace coconut oil in equal amounts. The texture will remain similar though the flavor may vary slightly.

→ Why is turmeric added to the curd?

Turmeric provides a natural golden-yellow hue without artificial food coloring. It's optional but recommended for achieving that classic bright lemon curd appearance.
