These easy-to-make chocolate cookies are so perfect to make for the holidays and your special celebrations. Today we are celebrating Valentine's Day by covering the cookie dough with pink, white, and red nonpareil sprinkles. Bake a batch of these sweet and festive cookies for your special someone!

Valentine's Sprinkles

You can use any color of sprinkles you like, think Christmas, Easter, Halloween, birthday parties, or just because you want to make some festive cookies with pretty sprinkles. No matter what you use, the colorful sprinkles look so pretty next to the dark chocolate cookie dough.

There are several types of sprinkles to use but I prefer using the little round candies called nonpareils. They stick better to the dough and keep their color. I have found the jimmie sprinkles don't stick as well and they tend to lose their color during baking, but you can use them.

Of course, another great reason to use the nonpareils is to watch them roll all over your countertop and then onto the floor! A broom is required when making these cookies.

Ingredients needed

The beauty of making a shortbread cookie recipe is it takes just a few ingredients, and this recipe takes just ten basic ingredients.

Shortbread cookies are really easy to make no matter what recipe you use.  These three cookie treats are always a favorite, try these Crispy Lemon Shortbread Cookies, and if you love spice, these Chai Shortbread Cookies are gluten-free and filled with lots of warming spices. Rose Petal Shortbread Cookies have just a hint of rose and cardamon flavors with rose petals baked on top, they are pretty and delicious. 

Let's bake some cookies

Step 1. You need to melt the chocolate first so it can cool. Place the chocolate chips in a small bowl and place them in the microwave for 30 seconds, take the bowl out and stir, then return to the microwave at 15-second intervals until the chocolate is melted.  If you are using a chocolate bar, chop the chocolate into small pieces similar to a chocolate chip.

Step 2. Mix the flour, salt, and cocoa powder together in a small bowl, using a wire whisk will break up any clumps of cocoa powder.

Step 3. In the bowl of a stand mixer, add the room temperature butter and both the sugars. Mix together until a nice creamy mixture forms.

Step 4. Add the egg and vanilla to the bowl and mix to incorporate. Scrape down the sides of the bowl.

Step 5. Add the melted chocolate to the bowl and mix on medium speed. Make sure the chocolate is not super hot, otherwise, it will melt the butter.

Step 6. Add the flour/cocoa powder mixture in half-cup amounts, mixing between each addition until the flour is no longer visible.

Step 7. Place the nonpareil sprinkles in a large container with sides that will fit the dough logs. The sprinkles do like to roll around so a deep-sided container works the best.

Step 8. Divide the dough in half and place it on a sheet of parchment or plastic wrap and roll the dough into a 6" x 2" log. The dough should be just a bit sticky, but not sticky enough that you can't work with it. Roll the dough back and forth with your hands to make the log nice and round.

Step 9. As soon as you make the dough log, place it in the sprinkles and cover the dough entirely.  The dough should be sticky enough from rolling and forming that the sprinkles will stick.

Step 10. Roll the sprinkle-covered log in a piece of parchment paper or plastic wrap and place in the refrigerator for 1 hour to chill.

Step 11. Heat the oven to 350 degrees F. and prepare two cookie sheets with parchment paper or a Silpat.

Step 12. Place the chilled cookie dough log on a cutting board and slice each log into ¼" slices, place the slices on the cookie sheet and bake for 12-13 minutes. Remove to a cooling rack.

Step 13. Adding the jumbo heart sprinkle on each cookie is totally optional but I think they just make the cookie look super cute. Stick one heart in the middle of each cookie before baking.

Step 14. Keep the baked cookies in an airtight container for up to two weeks.

Shortbread questions and tips

• Is a shortbread the same as a sugar cookie? They have similar ingredients but shortbread cookies have more butter to flour ratio which results in a more tender and crumbly texture.
• Shortbreads are supposed to be slightly crisp with a melting texture.
• Overworking or over beating the dough will make the cookies tough. Just mix until no flour is visible and be gentle when rolling.
• A good way to keep the cookie dough logs round is to place the rolls on a plastic flower former used for making fondant flowers, or cut a paper towel roll in half and place the dough into the cut-out half.
• Shortbread dough will keep well for up to a week in the fridge before being baked.
• The rolled dough can be frozen for three months. To bake let the dough thaw slightly and slice and bake as directed.  You want the dough to be firm when you slice it.
•        I have not frozen this dough with the sprinkles so I can't guarantee that they will stick when the dough thaws. I must try this though!

Don't forget the sprinkles

Make sure to buy your sprinkles early since they tend to run out of stock in early February. I've learned the hard way.  These sprinkles are more affordable in bulk, but I use these Wilton Valentine's Nonpareil Sprinkles and try to get them at Michael's or Hobby Lobby if I can find them.  And for the pink and red hearts, I used these Wilton Jumbo Heart Sprinkles.

These shortbread cookies stack perfectly in a mini bread pan for a pretty presentation and you can use this set of red and red stripe mini loaf pans for Christmas too! I love pretty towels and this set of striped heart towels are just right for Valentine's Day.

Why I love these cookies

• They have an incredibly deep dark chocolate flavor, just take a bite of one and you will understand what I mean..intense chocolate that is just so delicious.
• This recipe comes together in minutes.
• Since this recipe makes two cookie dough logs you can bake one today and chill the other for another day.
• Let's talk about color, these cookies are really, really pretty with the dark chocolate centers surrounded by colorful sprinkles. These shortbreads will look so festive on your cookie platters.
• Shortbread cookies last for over a week and are perfect for gift giving. You can even give the rolled cookie dough as a gift, just wrap it up in parchment and tie on the baking instructions with a pretty ribbon.
