Description

Developed from the same cookie dough used for my neapolitan cookies, these mint chocolate checkerboard cookies are styled and shaped to resemble a checkerboard pattern. It all starts from 1 basic cookie dough! For best success, read through the recipe and notes before beginning because there are a couple chilling and shaping steps.


Ingredients

Base Cookie Dough

  • 2 and 1/2 cups (313g) all-purpose flour (spoon & leveled)
  • 1/2 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1 cup (230g; 2 sticks) unsalted butter, softened to room temperature
  • 1 cup (200ggranulated sugar
  • 1 large egg + 1 egg yolk, at room temperature* (save extra egg white)
  • 1 and 1/2 teaspoons pure vanilla extract
  • optional for topping: 1 Tablespoon (15ml) water and 1/4 cup (50g) coarse sugar

For the Mint Dough

  • 1 teaspoon peppermint extract
  • optional: 1 drop green food dye

For the Chocolate Dough

  • 2 Tablespoons (11gunsweetened natural or dutch-process cocoa powder
  • 1 Tablespoon (15ml) milk
  • optional: 1 teaspoon espresso powder

Instructions

  1. Make the dough: Whisk the flour, baking powder, and salt together in a medium bowl. Set aside.
  2. In a large bowl using a hand mixer or a stand mixer fitted with a paddle attachment, beat the butter and granulated sugar together on medium-high speed until creamed, about 2 minutes. Add the egg, egg yolk, and vanilla extract and beat on high speed until combined, about 1 minute. Scrape down the sides and up the bottom of the bowl and beat again as needed to combine.
  3. Add the dry ingredients to the wet ingredients and mix on low until combined. Dough will be thick and sticky. Remove from the mixing bowl. No need to rinse out the mixing bowl.
  4. Divide the dough in half: There’s almost 4 cups of dough. Divide in half, a bit less than 2 cups each.
  5. Make the mint dough: Place half of the dough back into the mixing bowl. Add the mint dough ingredients. I recommend starting with 1 small drop of green food coloring. Beat on low speed until dough is combined. Add another small drop of food coloring if desired. For the pictured cookies, I used 1 drop of leaf green gel food coloring. Remove from the mixing bowl. No need to rinse out the mixing bowl, but feel free to wipe clean.
  6. Make the chocolate dough: Place other half of dough back into the mixing bowl. Add all of the chocolate dough ingredients. Beat on low speed until dough is combined.
  7. Shape & chill cookie dough for just 1 hour: Place doughs on a lightly floured work surface. It’s sticky, so do your best in this step. With lightly floured hands, carefully form both doughs into a 6 inch long rectangle block, 2 inches tall and 2 inches wide. Wrap both dough blocks up in plastic wrap or place on a plate and cover with aluminum foil. Refrigerate for just 1 hour. The *key* is to only refrigerate until the dough is less sticky, but still pliable enough to bend and shape. Chilling any longer will make it difficult to form a neat checkerboard pattern. If you need to chill it for longer than 1 hour, make sure you let it sit at room temperature for 15-30 minutes before continuing with the next step.
  8. Shape the dough: See photos in the blog post above for visuals of this step. Remove doughs from refrigerator and unwrap. Using a sharp knife, cut each block lengthways into 3 even strips. Then cut each strip into thirds again. You’ll have 9 thin strips from each dough block. My strips are usually a little uneven and messy, so for a neat checkerboard pattern, I always trim off* any rounded edges. Place 1 mint dough strip on your work surface. Line up a chocolate dough strip next to it. Line up a mint dough strip next to that. Top each with a row of alternating flavored dough strips, then top that with another row of alternating dough strips. Repeat with 2nd block, starting with a chocolate dough strip this time. As you’re working, press the strips tightly together to rid any gaps. (This is why it’s important the doughs are still a bit soft and pliable.) If desired to keep the checkerboard pattern neat, trim off* any rounded edges of your blocks.
  9. Chill for 2 more hours: Wrap each block of dough back up or cover and refrigerate for 2 more hours and up to 4 days.
  10. Preheat oven to 350°F (177°C). Line 2 baking sheets with parchment paper or silicone baking mats. Set aside.
  11. Slice and bake: Slice each block into 12 1/2-inch thick cookies. For thinner cookies, slice each block into 18 cookies, about 1/3-inch thick. (Bake time will be about 1 minute shorter.) Trim the cookie edges* to make neat squares, if desired.
  12. Arrange cookies 2-3 inches apart on the baking sheets. If desired, brush each lightly with egg wash (see recipe note) and sprinkle with coarse sugar. Bake for 12-14 minutes or until very lightly browned around the edges.
  13. Remove from the oven and allow cookies to cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
  14. Cookies stay fresh covered at room temperature for 1 week.

Notes

  1. Make Ahead Instructions: Baked cookies freeze well up to 3 months. Thaw overnight in the refrigerator and bring to room temperature, if desired, before serving. You can shape the cookie doughs in the checkerboard pattern blocks and chill in the refrigerator for up to 4 days (see step 9). You can also freeze the checkerboard pattern blocks for up to 3 months. Thaw overnight in the refrigerator then continue with step 10.
  2. Eggs/Egg Wash: You need 1 egg plus an additional egg yolk for the cookie dough. Save the extra egg white and mix it with 1 Tablespoon of water to make a simple egg wash. Brush this over each cookie as directed in step 12, then sprinkle with coarse sugar before baking. This gives the cookies a little crunch and sparkle.
  3. Trimmed Off/Excess Dough: In steps 8 and 11, I recommend trimming the dough strips, checkerboard blocks, and sliced cookies. This is optional, but it helps create neat looking checkerboard cookies. You’ll have some leftover cookie dough scraps. Discard or meld them together, roll out with a rolling pin (about 1/4 – 1/2 inch thick), and cut into shapes. Bake as directed in this recipe.
