As a classic Oreo cookie proves, the only thing better than a cookie is two cookies sandwiched together with frosting. I do enjoy making Gluten Free Oreos almost as much as I enjoy dunking them in a glass of milk before devouring them. But sometimes I crave lighter, brighter flavors.
So in the midst of my recent lemon obsession that produced several batches of moist Gluten Free Lemon Cupcakes, I needed more citrusy goodness. Bite-sized citrusy goodness. And that’s where these dainty little treats came from.
Lemon Sandwich Cookies Made Easy and Gluten Free
- A perfect little treat. These mini cookie sandwiches are so fun to just pop into your mouth. Plus, they are a pretty addition to a platter of gluten free desserts!
- Can be made from scratch. Of course, making the cookies and buttercream from scratch will give you the best flavors with super vanilla-y and buttery cookies paired with fresh and tangy frosting.
- Or use shortcuts. But store-bought wafers or frosting (or both) make it possible to assemble piles of them in no time,
Recipe Ingredients
As mentioned, all you really need are gluten free vanilla wafers and lemon buttercream frosting. My recipes for each of those give you all the details on how to make them, including all of my tips and tricks. But the instructions are included right in the recipe card at the bottom of the post. So you don’t even have to look anywhere else. Scroll all the way down for the full recipe card with measurements.
- Gluten Free Vanilla Wafers – Make a batch of homeamde Gluten Free Vanilla Wafers, or these cookie sandwiches also work beautifully with store-bought vanilla wafers like the ones from Kinnikinnick.
- Lemon Buttercream – I have an increidble reicpe for Lemon Buttercream Frosting, but to really simplify things, you can even use a can of Betty Crocker Lemon Frosting, which is gluten free.
How to Make Gluten Free Lemon Sandwich Cookies
There really isn’t much to say about making these cookie sandwiches. Of course, if you are making your cookies from scratch, you’ll need to prepare them based on the details in the posts linked above and in the recipe card. Then it’s just assembling.
- Pipe the frosting. Set your cookies out on a work surface and transfer the frosting to a piping bag. Place one vanilla wafer upside down. Gently squeeze the piping bag to pipe a small dollop or swirl of buttercream onto the bottom of the flipped-over cookie.
- Pipe and sandwich. Place another cookie on top and gently press down. Let the frosting set so it can firm up slightly.
Tips for Success
- Choose your tips. I think it’s fun to use a 1M star tip for a lovely little starburst, but you can use a #12 round tip for a little swirl. In a pinch, just spreading a small dollop of frosting on the cookies is fine, too.
- Don’t overfill. While I like a nice amount of icing, you don’t want to use too much or it will all just squish out when you take a bite.
- Let them set. Speaking of squishing out, if you let your cookies set for a bit, the surface of the frosting will crystallize and harden a little so that they are easier to transport and eat without getting too messy.
- Variations. Feel free to use the vanilla wafers as your base and fill them with vanilla frosting for double the vanilla goodness, get chocolaty with chocolate buttercream, or have a little fun with cookies and cream frosting. Or go super indulgent with gluten free cookie dough in the middle. You can also roll the edges in sprinkles, nonpareils, or coconut.
Storing Cookie Sandwiches
These lemon sandwich cookies will keep for up to a week in an airtight container at room temperature.
If you want to freeze them. I recommend freezing them in a single layer on a baking sheet before transferring to a plastic freezer storage bag or container so that the icing firms up and they don’t fall apart and make a mess. Enjoy them within a month or two.
