Ingredients: 1/2 cup unsalted butter (softened); 1/2 cup granulated sugar; 1 whole large egg; 1 teaspoon vanilla extract; 3 tablespoons cocoa powder; 1 teaspoon baking powder; 1/2 teaspoon salt; 1/2 teaspoon cinnamon (optional); 1 1/3 cups all-purpose flour; 1/2 cup semi-sweet chocolate (melted); 1/2 cup butter; 2 tablespoons cocoa powder; 3 tablespoons milk; 1 teaspoon white vinegar; 2 1/2 cups powdered sugar

Ingredients

1/2 cup unsalted butter (softened)

1/2 cup granulated sugar

1 whole large egg

1 teaspoon vanilla extract

3 Tablespoons cocoa powder

1 teaspoon baking powder

1/2 teaspoon salt

1/2 teaspoon cinnamon (optional)

1 1/3 cup all-purpose flour

1/2 cup semi-sweet chocolate (melted)

1/2 cup butter (for icing)

2 Tablespoons cocoa powder (for icing)

3 Tablespoons milk (for icing)

1 teaspoon white vinegar (for icing)

2 1/2 cups powdered sugar (for icing)

Instructions

Step 1: Preheat your oven to 350º F (175º C).

Step 2: In an electric mixer, cream together the softened butter and granulated sugar until creamy and well combined. Add the egg and vanilla extract, beating until fully incorporated.

Step 3: Mix in the cocoa powder, baking powder, salt, cinnamon (if using), and flour until a smooth batter forms. Stir in the melted semi-sweet chocolate until evenly combined.

Step 4: Scoop the dough into 18 equal balls and place them onto a lined baking sheet. Bake for 8 minutes, or until the cookies are just dry on the top—avoid overbaking for the best texture.

Step 5: Remove the tray from the oven and allow the cookies to cool completely on the baking sheet.

Step 6: To prepare the icing, melt 1/2 cup butter in a saucepan. Add 2 tablespoons cocoa powder, 3 tablespoons milk, 1 teaspoon white vinegar, and 2 1/2 cups powdered sugar. Whisk together until smooth and pourable. If too thick, add milk 1 teaspoon at a time to reach the right consistency.

Step 7: Pour the frosting evenly over the cooled cookies on the baking tray. Let them sit for a couple of hours so the icing can fully set.

Step 8: Once set, remove the cookies and store them in an airtight container for up to 3 days.

Tips & Variations

For extra richness, use high-quality dark chocolate when melting for the batter.

Add chopped nuts or chocolate chips to the dough for extra texture.

If you prefer a spicier kick, increase the cinnamon or add a pinch of cayenne pepper to the batter.

Make the cookies gluten-free by substituting all-purpose flour with a 1-to-1 gluten-free flour blend.

Storage

Store these cookies in an airtight container at room temperature for up to 3 days. The icing will stay soft and delicious. If you want to keep them longer, refrigerate for up to a week, letting them come to room temperature before serving. Avoid freezing, as the delicate icing texture may be affected.

FAQs

Can I make these cookies ahead of time?

Yes, you can bake and frost the cookies ahead. Let them cool completely before icing, then store in an airtight container. They are best enjoyed within 3 days for optimum freshness.

What if I don’t have white vinegar for the icing?

If you don’t have white vinegar, you can substitute with lemon juice or omit it altogether. The vinegar helps balance sweetness but isn’t essential to the overall flavor.
