Ingredients and Preparation

Before you start, gather your ingredients and tools. Having everything ready makes baking smoother and more enjoyable.

For the Chocolate Cupcakes:

¼ cup (45 g) semisweet chocolate chips
¼ cup (22 g) dark cocoa powder
¾ cup (177 ml) boiling water
¾ cup (94 g) all-purpose flour
¾ cup (150 g) granulated sugar
½ teaspoon baking soda
½ teaspoon salt
⅓ cup (80 ml) vegetable oil
2 large eggs, room temperature
2 teaspoons vanilla extract

For the Cookies and Cream Buttercream Frosting:

1 cup (227 g) unsalted butter, softened to room temperature
2 ½ cups (300 g) powdered sugar
2 teaspoons vanilla extract
¼ teaspoon salt
2 tablespoons (30 ml) heavy cream or milk
½ cup (50 g) finely crushed Oreo cookie crumbs

For the Chocolate Ganache:

¼ cup (45 g) semisweet chocolate chips
2 tablespoons (30 ml) heavy cream

Garnish:

12 Oreo cookies, halved

Step-by-Step Instructions

1. Prepare the Chocolate Mixture

Preheat your oven to 350°F (177°C). Line a 12-cup muffin pan with cupcake liners.
In a small heatproof bowl, combine the semisweet chocolate chips and cocoa powder.
Pour the boiling water over the chocolate and cocoa, stirring until the chocolate melts completely and the mixture is smooth. Set aside to cool slightly.

2. Mix the Dry Ingredients

In a large mixing bowl, whisk together the flour, sugar, baking soda, and salt until evenly combined.

3. Combine Wet Ingredients and Batter

Add the vegetable oil, eggs, and vanilla extract to the dry ingredients. Mix gently to combine.
Slowly pour the cooled chocolate mixture into the batter while stirring gently. Mix until just combined. Avoid overmixing to keep cupcakes tender.

4. Bake the Cupcakes

Evenly divide the batter into the prepared cupcake liners, filling each about two-thirds full.
Bake for 18 to 22 minutes, or until a toothpick inserted into the center comes out clean.
Remove from the oven and allow cupcakes to cool in the pan for 10 minutes. Transfer to a wire rack to cool completely before frosting.

5. Prepare the Cookies and Cream Buttercream

Using a stand or hand mixer, beat the softened butter on medium speed until creamy and smooth (about 2 to 3 minutes).
Gradually add the powdered sugar, about half a cup at a time, mixing well after each addition to avoid lumps.
Add the vanilla extract, salt, and heavy cream. Beat on high speed for 3 minutes to create a light and fluffy frosting.
Fold in the crushed Oreo cookie crumbs gently with a spatula, ensuring even distribution but not overmixing.

6. Make the Chocolate Ganache

Place the chocolate chips in a small heatproof bowl.
Heat the heavy cream in the microwave or on the stove until just about to boil.
Pour the hot cream over the chocolate chips and let sit for 2 minutes.
Stir until smooth and glossy. Allow to cool slightly so it thickens but remains pourable.

7. Assemble the Cupcakes

Fit a piping bag with your favorite tip (star or round) and fill with the cookies and cream buttercream.
Pipe a generous swirl of frosting onto each cooled cupcake.
Drizzle the chocolate ganache over the frosting using a spoon or squeeze bottle.
Top each cupcake with half an Oreo cookie for garnish.

Beginner Tips and Notes

Use Room Temperature Ingredients: Eggs and butter at room temperature blend better for smoother batter and frosting.
Avoid Overmixing: Stir the batter until just combined to keep cupcakes tender and airy. Overmixing develops gluten, leading to dense cupcakes.
Crush Oreos for Texture: For the frosting, crush cookies into small bits, not powder, for a pleasant crunchy texture. A food processor or a rolling pin and ziplock bag works well.
Frosting Consistency Adjustments: If your buttercream is too stiff, add a teaspoon of heavy cream or milk at a time. If too runny, add more powdered sugar gradually.
Ganache Temperature: Drizzle ganache when it’s cool but still pourable. Too hot, it will melt the frosting; too cold, it won’t spread nicely.
Storage: Keep cupcakes in an airtight container at room temperature for up to 2 days or refrigerate for 4 days. Let refrigerated cupcakes warm to room temperature before serving for the best flavor.
Make Ahead: Cupcakes and frosting can be made a day ahead. Store cupcakes and frosting separately and assemble just before serving for freshness.

Serving Suggestions

Serve these cupcakes at room temperature alongside a simple glass of milk or your favorite hot beverage like coffee or tea to balance the sweetness.
For a party, place cupcakes on a tiered stand with fresh berries or a fruit platter to add a fresh contrast to the rich cupcakes.
Mini versions baked in mini muffin tins make great bite-sized treats for gatherings or kids’ parties.
For an elegant dessert, pair cupcakes with a scoop of vanilla ice cream and a drizzle of chocolate sauce.
