The Story: Baking, Birds, and Lemon Curd

Let me tell you, the first time I made these lemon sandwich cookies with lemon curd, I was elbows-deep in flour one unusually sunny April afternoon, birds arguing outside like they’d lost their minds over some leftover toast. I nearly knocked over the jar of coconut oil (again) and, honestly, I felt like these cookies pretty much chose the mood for the day: bright, tangy, and a bit unpredictable. My mum used to make lemon bars, but I’ve always been partial to cookies, especially the ones you sandwich together with something sticky. Plus, it’s kind of fun when you end up with jammy lemon curd stuck on your nose (no shame, happens every time). Anyway, if you love citrus or need a pick-me-up treat, these are an absolute riot.

Lemon Sandwich Cookies With Lemon Curd (Vegan, Gluten Free)

Why You’ll Love This Cookie Sandwich Situation

I make this when I want something cheery (cloudy days, birthdays, Wednesdays—doesn’t matter). My family basically demolishes them before I blink; my partner claims they’re the only reason he tolerates all my baking experiments. And if you’ve ever bought gluten free cookies that taste more like cardboard than dessert—these are not that. The cookies are soft but kinda snappy around the edges, and the homemade lemon curd… well, sometimes I catch myself eating it with a spoon. Oh, my neighbor once declared these “the only vegan gluten free thing I’ll eat without complaining”—so there’s that, too.

The Stuff You’ll Need (with My Casual Swaps)

1 3/4 cups gluten free flour blend (Bob’s Red Mill is my go-to, but honestly any decent blend seems fine—my friend used some random brand from Aldi and it worked)
1/2 cup almond flour (or ground hazelnuts if you’re feeling fancy; I’ve done both with equal success)
1/2 cup coconut oil, solid (sometimes I use vegan butter; it’s a bit softer but not bad)
3/4 cup powdered sugar (for real, sift it if you don’t want lumps)
Zest of 1 big lemon (go wild if you like it extra zingy)
1/4 tsp fine sea salt (I’ve forgotten it before and survived, but flavor’s better with)
2 tbsp lemon juice (from that same lemon’s good—no need to grab another)
1 tsp vanilla extract (totally optional, but I like the coziness it adds)
Up to 2 tbsp non-dairy milk (like almond or oat; only if dough is crumbly)

For the quick vegan lemon curd (see, this part is worth it!):

1/2 cup fresh lemon juice (about 2 lemons; sometimes I cut it with a splash of orange juice when I’m low on lemons)
1/3 cup maple syrup (agave works too, but maple’s my jam)
2 tbsp cornstarch (I’ve tried arrowroot, but cornstarch is less fussy)
1/4 cup canned coconut milk (sometimes I just use soy milk—it’s slightly less creamy but still tasty)
Pinch of turmeric, for color (strictly optional—no big deal if you skip it)
1/2 tsp vanilla extract

How I Make ‘Em (In Between Sips of Tea)

Make the lemon curd first, because it needs to cool: Whisk together lemon juice, maple syrup, cornstarch, and coconut milk in a saucepan (don’t panic if it looks wonky at first—it smooths out). Cook on medium, whisking like a maniac, ‘til it thickens—takes about 5 mins. Remove form heat, stir in vanilla and turmeric, and let it get to room temp. Stick it in the fridge, covered.
For the cookies: Mix coconut oil and powdered sugar with a fork or mixer (yep, it’s a bit messy—I always get sugar dust on my shirt). Add lemon zest, lemon juice, and vanilla. Combine well; it’ll look like very thick paste.
Add in the gluten free flour blend, almond flour, and salt. Stir until a dough does its thing. If too dry—add non-dairy milk, a splash at a time. When the dough sticks together but isn’t sticky, it’s ready.
Pat/roll the dough to about 1/4-inch thick. I use a floured glass to cut circles (pro tip: use what you’ve got—no need for special cutters). Place on a lined baking tray as you go.
Preheat oven to 350°F (180°C). While it heats, stick the tray in the fridge for 10 mins—makes the shapes hold.
Bake for 10-12 minutes, just until the edges get a tiny bit golden. They firm as they cool, so don’t overbake (unless you like cookies that can stand in for hockey pucks).
Let cool on the tray for 5 mins (they might break if you rush), then move to a wire rack to cool completely. This is where I sneak a taste—no apologies.
When cookies are cool, spoon about a teaspoon of the lemon curd onto half the cookies. Top with their partners. Don’t worry if curd squishes out—messy tastes better.

Notes No One Tells You (Until Too Late)

If the dough’s sticky, chill it for 15 mins—it’s easier to work with, especially if your kitchen’s like a sauna.
Don’t skip that non-dairy milk if things look dry—the dough likes a bit of moisture (not a flood though, learned that the hard way).
Store leftover curd in the fridge. I sometimes drizzle it over pancakes—wild, I know.

Past Experiments: What Else Works?

Swapped in lime for lemon: works but is almost too tart. Maybe half-and-half?
Chocolate drizzled over the top once—looked fancier, but my sister complained it hid the lemon. So, jury’s out.
I tried millet flour once—don’t bother. Texture’s all wrong; just stick to almond or hazelnut for the swap.

The Stuff You Might Need (Or Mightn’t)

Baking tray, parchment (I’ve gone without parchment—cookies survived, just stickier cleanup)
Rolling pin is great, but a wine bottle works in a pinch (not even joking—done it more times than I admit)
Whisk, mixing bowls, cooling rack
Cookie cutter—or, again, a glass (I learned this form an impatient friend in Glasgow… thanks Jen!)

Keeps Fresh, Kinda…

Store assembled cookies in an airtight container for two, maybe three days. Honestly, in my house, they never last more than a day. If they even survive an afternoon, I’d be shocked.

How I Serve ‘Em

I like to pile these high on a platter and dust with a touch of extra powdered sugar. Sometimes I wedge a few in a lunchbox for a mid-afternoon surprise (always better than a bruised apple, right?). Oh, and at birthdays, we actually sandwich birthday candles between two—strange tradition, great photos.

If I Could Do It Again… My Hard-Earned Tips

I once rushed chilling the cookie dough—big mistake, cookies spread all over. Let ‘em chill if you’ve got time; turns out it’s worth it.
Ignore the urge to overfill with curd. I know, it’s tempting, but then everything oozes. Go small and add a bit more if you must.
Oh, and double the curd. Trust me. You’ll find reasons to use it within days.

Blunt Answers to Real Questions

Can I make the curd ahead? Yep! Make it a day or two before—just give it a quick stir before using. Sometimes I even freeze little tubs for emergencies (midnight snacking IS an emergency).
Help, my dough’s too dry! Add that non-dairy milk bit by bit; it’ll come together. I had a batch where I thought it’d never stick and then suddenly, boom, perfect dough.
Do these travel well? Actually, yes—the cookies alone do. Once sandwiched, though, pack gently. I learned this after finding a lemony blob in my bag. Still tasty, just… not picture perfect.
Too lemony? Try substituting a bit of orange or mellow it out with extra vanilla. I mean, lemon’s the point, but hey, it’s your kitchen!
Do I have to use almond flour? Technically no. I’ve used hazelnut and once… oat flour. Almond’s my fav for texture, but it’s not a dealbreaker.

Well, now I’m hungry just thinking about these. If you try ‘em, let me know how your batch turns out – or, you know, send cookies, that works too!
