Martha Stewart's Peanut-Butter Surprises

I make this recipe every year for Christmas. Definitely a family favorite and one of my most requested recipes. (*Note - prep time is estimated and does not include chill time)

• Ready In: 42 mins
• Yields: 2 dozen

Ingredients

• 2  cups all-purpose flour
• 1⁄2 cup  Dutch-processed cocoa powder
• 1⁄2 teaspoon baking powder
• 1⁄2 teaspoon baking soda
• 1⁄2 cup unsalted butter, room temperature
• 1⁄2 cup vegetable shortening
• 1⁄2 cup granulated sugar
• 1 1⁄4 cups light-brown sugar, firmly packed
• 2  large eggs
• 1  teaspoon pure vanilla extract
• 1  cup  semi-sweet chocolate chips
• 1⁄2 cup creamy peanut butter

Directions

1. Preheat oven to 350 degrees. Line two baking sheets with parchment. Sift together flour, cocoa powder, baking powder, and baking soda, and set aside.
2. In the bowl of an electric mixer fitted with the paddle attachment, beat butter, vegetable shortening, granulated sugar and 1 cup brown sugar on medium speed until light and fluffy, about 2 minutes. Add eggs, one at a time, mixing until fully combined between additions. Add vanilla; beat to combine. Gradually add dry ingredients; mix on low speed until fully combined. Add chocolate chips; mix on low just until combined. Cover bowl with plastic wrap; chill until firm about 1 hour.
3. In a small bowl using a rubber spatula, stir together peanut butter and remaining 1/4 cup brown sugar.
4. Drop 1 tablespoon of dough at a time onto baking sheets, spacing cookies about 2 inches apart. Make a thumbprint in the center of each cookie. Fill thumbprint with 2 teaspoons peanut butter mixture. Top with a second tablespoon of flattened dough. Carefully mold dough to cover "surprise.".
5. Bake until firm, about 12 minutes, rotating halfway through. Transfer baking sheets to wire racks to cool for 5 minutes. Remove cookies from baking sheets, and let cool completely on wire racks.
