Could you tell me how to prepare Fudgy Brownie Cookies?
Here's a recipe for Fudgy Brownie Cookies:

Ingredients:

• 10 oz semi-sweet chocolate chips
• 1/2 cup unsalted butter
• 2 tablespoons vegetable shortening
• 1 1/4 cups all purpose flour
• 1/4 cup dutch processed cocoa  powder
• 1 teaspoon baking powder
• 3/4 teaspoon fine sea salt
• 1 teaspoon instant espresso powder
• 1 cup granulated sugar
• 1/4 cup dark brown sugar
• 2 whole eggs, plus one egg yolk, room temperature
• 2 teaspoons vanilla extract
• 1/2 cup semisweet chocolate chip

Instructions:

1. Using a microwave-safe bowl, melt the chocolate, butter, and shortening in the microwave in 30-second increments until completely melted, stirring in between each increment. Set aside to cool slightly as you complete the other steps.
2. In a medium bowl, whisk the flour, cocoa powder, baking powder, salt, and espresso powder until combined.
3. In a large bowl using a hand mixer or a stand mixer with a paddle attachment, whip the sugar and eggs on high speed for a full 5 minutes. The mixture will look frothy and lighter in color.
4. Add the vanilla, followed by the mixture of melted chocolate, butter, and shortening in a slow and steady stream on low speed until fully combined.
5. Add the dry ingredients in two additions and mix on low speed by hand until just combined. Don’t over-mix. Finally, mix in the mini chocolate chips.
6. Cover and chill the cookie dough for 1 hour in the fridge.
7. Preheat your oven to 350°F and prepare 2 half sheet trays with parchment paper. Scoop dough into balls, rolling them to make them slightly taller before you place them on the tray 2-3 inches apart, no more than 8 cookies per tray. Bake for 13-16 minutes until the edges look set.
8. Remove from the oven and let cool for at least 10 minutes before serving.

Enjoy your Fudgy Brownie Cookies!
