Instructions
Chocolate Ganache
Place the chocolate in a small/medium sized bowl so that it's spread across the bottom evenly.
Heat the heavy whipping cream in the microwave or over the stove (medium-low heat) until it comes to a boil. Stir frequently to ensure it's heated evenly.
Pour the hot cream over the chocolate so that it's completely covered, then place a lid or plate on top to trap in the heat. Wait for 5 minutes.
Using a spatula, stir the mixture in a circular motion until it's a smooth, homogenous mixture. Let it cool and thicken while making the cookies. (You can speed it up by placing it in the refrigerator, but be sure to stir it every once in a while.)
Peanut Butter Cookies
Preheat oven to 350°F and line 1-2 baking sheets with parchment paper (optional for easier cleanup).
In a small/medium bowl, whisk together the flour, baking soda, cinnamon and salt. Set aside.
In a large bowl with a hand mixer or stand mixer with a paddle attachment, cream together the butter and sugars for about 2 minutes. Scrape the sides as necessary. Add the peanut butter, egg and vanilla extract, mixing well after each addition.
Add the dry ingredients to the wet ones and gently stir to combine until all flour streaks have disappeared.
Using a medium cookie scoop, grab scoopfuls (about 2 tablespoons each) of cookie dough and roll them into neat balls. Place them on the baking sheets about 2 inches apart.
Bake the cookies until the edges are tan and they start to crack slightly on top (about 10-14 minutes). Let them cool on the pan for a few minutes, then transfer them to a cooling rack.
Assemble the Whoopie Pies
Once the cookies are completely cooled and the ganache has thickened, transfer the ganache to a piping bag with a medium round tip (or a plastic bag with the end cut off, about ½ inch diameter).
Pair the cookies up and pipe chocolate swirls onto half of them. Sandwich them together with the unfrosted cookies and enjoy!
