Key Lime Pie Thumbprints

Thumbprint cookies… A versatile cookie that traditionally has a shortbread base and an indent in the center filled with jam, chocolate, dulce de leche, or for today’s cookie, a key lime chocolate filling. Don’t worry its white chocolate, not semi or milk chocolate. I definitely don’t think these cookies would be as appetizing if key lime juice was mixed in with either of those chocolates. Somehow I think the key lime flavor would be lost. Now, as a filling for a truffle I think it would be perfect. I may have had one or two of those before so I am speaking from experience.

I have a friend who has all of a sudden fallen in love with Key Lime Pie. I’ve been making it for a few years now but all of a sudden when I made it last year it was like he was eating it for the first time. And when I asked some friends what cookies they wanted for Christmas last year (just over a month ago sounds so much better to say this early in the year) he suggested rugelach and a key lime pie. Which got me thinking of a key lime pie cookie since I wasn’t in the mood to make a pie (which I ultimately ended up making anyway.) So, I initially made the Key Lime Crinkles that were part of Cookie Palooza. While they were delicious, they lacked the key lime filling he enjoys so I knew I would have to try these thumbprints instead and I am happy to say that these were a hit with everyone who tried them. A cookie that will definitely be in my cookie rotation. Thanks to the graham cracker crumbs in the base of the cookie this is almost like enjoying a piece of key lime pie, but, in a bite size grab and go form. And while the key lime flavor is apparent in the filling I could imagine adding another tablespoon or so would kick it up even more.

Key Lime Pie Thumbprints

  • Servings: 40 cookies
  • Print

Ingredients:

Cookies:

1 cup unsalted butter, at room temperature

1/3 cup sugar

1/3 cup light brown sugar

1 teaspoon vanilla extract

1 large egg yolk

2 cups flour

1/2 cup graham cracker crumbs (4 graham crackers)

2 teaspoons cornstarch

1/2 teaspoon salt

 

Filling:

1 cup white chocolate chips

1/2 cup sweetened condensed milk

3 tablespoons key lime juice

2 teaspoons lime zest (1 lime)

 

Directions:

Line cookie sheets with parchment paper.

Combine the butter and sugars in a large bowl and beat on medium speed until creamy.

Switch the mixer to low and add in the egg yolk and vanilla extract and continue mixing until well combined, scraping the sides of the bowl as necessary.

In a separate bowl which together the flour, graham cracker crumbs, cornstarch and salt.

Gradually add the flour mixture to the butter mixture, mixing until the ingredients are incorporated. Scraping the sides of the bowl as necessary.

Scoop 2 teaspoons of the dough and roll into a smooth ball and place on the prepared cookie sheets about an inch apart. (Using a standard cookie scoop I scooped the dough and then divided the dough in half to get the 2 teaspoon amount)

Using the back of a rounded teaspoon gently press an indent in the center of each ball. I have tried using my thumb for this step, but, have found that a teaspoon produces a much better circular shape.

Chill the dough in the freezer for at least 30 minutes. Freezing the dough prevents the cookie from spreading too much while baking giving you more room for your filling.

Preheat the oven to 350 F.

Bake the cookies for 10-11 minutes. Immediately after removing the cookie from the oven press the teaspoon into the indent once again to redefine it. Let the cookies cool completely on the sheets before filling them.

To make the filling… Combine the chocolate chips, condensed milk and key lime juice in a small saucepan and cook over medium-low heat. Stir frequently until the chocolate chips have melted and the ingredients are well combined. Stir in the lime zest and continue stirring until the mixture begins to boil. Reduce the heat to low and using a teaspoon spoon the filling into the cookies.

Allow the filling to cool and set before serving. When storing the cookies, keep in mind that the filling may remain a bit tacky. Store in an airtight container at room temperature.

Cookie Palooza: Key Lime Pie Tassies & Pistachio Cookie Cups

These are definitely not your typical cookies, they’re more like mini tarts, but are cookies nonetheless. I tried to do some research as to how a tassie got its name and what the difference was between a tassie and a cookie cup, but, I came up empty handed… Oh well. If anyone knows feel free to share it in the comments sections below!

These weren’t on my original list of cookies for this week, originally I was planning on an Earl Gray Tea Cookie that called for cardamom. Cardamom became the main flavor of the cookie as opposed to the titled earl gray and while that was fine as the cookie tasted good, after making the cookie 2 different times – following the directions exactly the first time and making some variations the second time – both times the cookie came out too dense. I knew then that the recipe was a fail and searched for something else. Hence these tassies and cookie cups, both of which turned out to be a major hit. On a side note, I had a second fail with another cookie recipe as well. It was for a Maple Pecan Chocolate Cookie that called for maple sugar. I had to do some searching for the maple sugar and while the cookie dough – yes, I eat raw cookie dough from time to time – tasted delish with a maple flavor the cookie itself lost the maple flavor and was flat, chewy in the middle and crispy along the edges. Not at all what I was expecting. I read the directions numerous times afterwards to make sure I added the right amount of ingredients and such and I had. I wonder if anyone tests some of these recipes before publishing them sometimes.

Back to the cookies at hand. When I initially made them I didn’t want to make too many – each recipe calls for 24 – just in case this was another fail. But, after friends tried them it was evident that I needed the full amount so I made them again for Thanksgiving and once again they were a hit.

Here are some tips to make these…

To help divide the dough into 24 somewhat evenly balls I formed the dough into a 6×4-inch rectangle on a lightly floured surface and cut it into 24 squares. I began by scoring it with a pizza cutter and then actually cut it once it had all been scored.

For the Pistachio Cookie Cups to save money, but not time, I opted to buy roasted unsalted pistachios in their shells and shelled and chopped them myself.

Which I then mixed with an egg, confectioners’ sugar and chopped dried apricots for the filling.

Since key limes aren’t always available in my area and I do love key lime pie, I usually have key lime juice in my fridge. You can find it in the juice aisle or oddly enough at some supermarkets they have it in the baking aisle. I can’t say for sure if using the juice from key limes as opposed to regular limes alters the flavor of the tassies since there are other ingredients involved, but, I do know that there is a difference in the flavor between the two of them. It’s all about preference and authenticity to the recipe when it comes to which lime or lime juice you choose.

The Pistachio Cookie Cups are baked filled while the Key Lime Pie Tassies pastry cup is baked first and then filled with the key lime filling and then baked again. Don’t worry, the pastry cup won’t burn or dry out… that’s what I initially thought would happen. Both of these are delicious and it’s hard to choose a favorite and thankfully they are easy enough and quick enough to bake that you could bake them both to enjoy them at the same time.

And while the Key Lime Pie Tassies are good on their own, I decided to add a little homemade whipped cream and lime zest to some of them for a little more sweetness.
