1 teaspoon baking powder
1 teaspoon ground cinnamon (optional)
1/4 teaspoon baking soda
1/2 teaspoon salt
1/2 cup unsalted butter, softened

Chocolate Frosting:
5 tablespoons unsalted butter
5 tablespoons heavy cream

1 teaspoon vanilla extract
1/4 teaspoon salt
2 cups powdered sugar


Step 1: Simmer the chocolate chips on top of a double broiler.

Step 2: Stir and scrape the sides using a spatula to avoid burning. Heat for i5 minutes or until the chocolate is melted completely. Allow it to cool.

Step 3: Prepare the oven and preheat to 175 degrees C or 350 degrees F.

Step 4: In a medium mixing bowl, add in the cocoa powder, flour, cinnamon, baking soda, baking powder, and salt. Whisk until well mixed.

Step 5: In another mixing bowl, add in the butter and sugar. Beat using an electric mixer until well mixed. Add in the vanilla extract and eggs then beat until creamy.

Step 6: Transfer the melted chocolate into the egg mixture and stir until well blended.

Step 7: Transfer in 1/2 of the dry ingredients into the egg and chocolate mixture then stir until well combined. Add in the buttermilk and the rest of the dry ingredients. Stir until well combined.

Step 8: Scoop the mixture and drop them into the baking sheets. Make sure to leave 1 1/2-inches space on each cookie.

Step 9: Place inside the preheated oven and bake for 8 to 10 minutes or until cooked through.

Step 10: Remove from the oven and let it sit on a wire rack to cool at room temperature.

Step 11: In a saucepan, add in the butter, vanilla extract, heavy cream, salt, and cocoa powder. Turn the heat to low and cook until the butter is melted completely. Add in 1 cup of sugar at a time and whisk. Whisk for 1 to 2 minutes or until the frosting is smooth.
