Lemon Blueberry Thumbprint Cookies are a sweet treat that make a delightful dessert or midday snack. A lemon shortbread cookie is topped with blueberry jam and a delectable lemon-flavored glaze. Once you see how easy it is to make thumbprint cookies, be sure to try my Turtle Thumbprint Cookies and Raspberry Thumbprint Cookies.

Lemon Blueberry Thumbprint Cookies

The foundation for this amazingly simple (yet delicious) cookie is shortbread. I have always loved shortbread cookies, but after some research, I have a newfound appreciation for them! Shortbread dates many many years to 12th century Scotland.  Shortbreads were a delicacy at that time and were reserved for only special events.  So what makes a shortbread? Butter. Shortbread actually started out as a biscuit bread, but by adding in a large amount of butter the dish became crumbly. 

Back in the day, the term “short”, meant “crumbly” (at least when it applied to baked goods).  For this thumbprint recipe, I added a touch of lemon flavor to the cookie and used a blueberry jam as the centerpiece.

There are two parts to this cookie–the shortbread cookie and the toppings. Both parts are easy to make and will taste like they were a lot more work than they are!

How to Make Lemon Blueberry Thumbprint Cookies

These cookies are impressive.  They look like they take quite a bit of effort.  Spoiler Alert!  They don’t.  These cookies are so simple and whip together in just minutes! 

To make this Lemon Blueberry Thumbprint Cookie recipe you simply cream together butter and sugar, add in some lemon zest, egg yolk, and some flour.   Roll this out into 1 1/2 in cookie balls and fill with jam.   The hard work is done!  You pop them in the oven for about 14 minutes.   While the cookies are baking you throw the glaze together.

Making the Glaze

Yes, I mentioned how easy it is to make the glaze, but things can definitely go wrong! You wouldn’t think that the sweet topping with just three ingredients could cause such grief! Well, it can…but, there are some things to be aware of so you can adjust ingredients if you need to. One thing to consider is making sure you are using the best ingredients in the glaze.

Humidity and tiny measurement differences can also make or break a glaze recipe. You need to be flexible in changing amounts as you need to. Finally, don’t overmix for the best consistency, and try not to overthink it. Play around with the amounts until it meets your approval. 

The Trick to Perfect Thumbprint Cookies

The trick to making the perfect thumbprint is not to use your thumb.  Shh, don’t tell anyone.  I like to use the edge of my spoon.  I keep a small plate of flour out and dip the spoon in to prevent sticking and then lightly press to make your circular center.  Now, using your thumb will work too, have no fear. The other tip I will give you on these cookies is to actually roll out the ball with your hands.  If you use a cookie scoop you will get the right size, but don’t skip out on the hand rolling.  This motion seals the cookie dough together and prevents the base from cracking under heat.

How to Store Thumbprint Cookies

Are you really worried about having extra?  Just kidding.  Yes, you can freeze and store Lemon Blueberry Thumbprint cookies.

After baking, allow the cookies to cool completely, and then place them in a freezer-safe container.  I would suggest setting them flat and then adding a layer of parchment paper on top.

  1. Could I use a sil-pat instead of parchment paper? Would there be an impact to soft or hardness to the bottoms? Thank you!

  2. How come when you print the recipe you don’t get the colored picture of the dessert? It shows it right before you got to print then it doesn’t.
