Ingredients
- 120 g boiling water
Boiling water helps to activate the cocoa powder, ensuring that the chocolate flavor is deep and rich in the cupcakes. It also contributes to the moisture content, resulting in a tender crumb. - 160 g all-purpose flour
The backbone of the cupcake, all-purpose flour provides structure. It balances the moisture from other ingredients, ensuring the cupcakes rise nicely while maintaining a soft texture. - 200 g granulated sugar
Sugar sweetens the cupcakes while also aiding in browning during baking, giving that desirable golden hue. It plays a critical role in achieving the right texture—fluffy and light. - 50 g unsweetened cocoa powder
Cocoa powder is key for delivering the rich chocolate flavor. It also contributes to the color of the batter, making it inviting and decadent. - 1 teaspoon instant espresso powder
This ingredient enhances the chocolate flavor without adding a coffee taste. It helps to intensify the richness, making the overall cupcake experience more pronounced. - ½ teaspoon baking powder
Baking powder is a leavening agent that helps the cupcakes rise, giving them a light and airy quality. It reacts with moisture in the batter, creating tiny bubbles that expand during baking. - ½ teaspoon baking soda
Working in tandem with baking powder, baking soda aids in leavening as well, contributing to the overall fluffiness and helping the cupcakes rise to perfection. - ½ teaspoon salt
Salt enhances the chocolate flavor while balancing the sweetness of the sugar. It’s a small amount that makes a significant impact on the overall taste. - 120 g sour cream, room temperature
Sour cream adds moisture and a slight tang, contributing to a tender crumb. Its acidity also helps to balance the sweetness, resulting in a well-rounded flavor profile. - 75 g vegetable oil
Oil keeps the cupcakes moist and adds richness to the batter. Unlike butter, oil maintains a more consistent moist texture throughout the baking process. - 1 ½ teaspoon vanilla extract
Vanilla extract levels up the flavor profile, providing a warm and sweet backdrop that enhances both the chocolate and sweetness in the cupcakes. - 50 g granulated sugar (for frosting)
Additional sugar is essential for the frosting, providing sweetness and stability to the mixture. It helps achieve the fluffy and delightful texture that complements the richness of the cupcakes. - 25 g agave syrup
Agave syrup adds sweetness and a unique flavor to the frosting. Its liquid form helps to keep the frosting smooth and pourable when needed. - 60 g whole milk
Milk is critical for creating a creamy consistency in the frosting. It helps achieve the right texture and allows for easier spreading or piping. - 100 g semi-sweet chocolate
Melting this chocolate into the frosting creates a rich and luxurious topping for the cupcakes, enhancing the overall chocolate-y experience. The creaminess of the chocolate pairs perfectly with the soft cupcake. - 10 g cocoa powder (for frosting)
Cocoa powder in the frosting provides added depth of flavor and enhances the chocolatey taste. It also contributes to the visual appeal, giving the frosting a richer color. - 15 g butter, cold
Cold butter in the frosting helps to achieve a lighter texture. It gives stability and richness, making the frosting not only delicious but also easy to work with.
Directions & Preparation
Step 1: Preheat the oven and prepare the cupcake pan.
Start by preheating your oven to 160ºC (320ºF) and lining a 12-cup cupcake pan with liners. This is a crucial step as it ensures an even baking temperature so that the cupcakes rise correctly. Using cupcake liners not only helps with easy removal after baking but also adds a decorative touch to your presentation.
Step 2: Combine dry ingredients.
In a large bowl, sift together the flour, sugar, cocoa powder, espresso powder, baking powder, baking soda, and salt. Sifting helps to aerate the dry ingredients and ensures that there are no lumps. This step is important for achieving a uniform batter, which leads to evenly baked cupcakes. Give them a gentle stir to mix everything well.
Step 3: Prepare the wet ingredient mixture.
In another mixing bowl, combine the boiling water, sour cream, vegetable oil, eggs, and vanilla extract. Stir them together gently, ensuring that the mixture is well combined without overmixing. Overmixing can lead to denser cupcakes, so aim for just enough blending until smooth. The boiling water activates the cocoa and adds moisture, while the sour cream enriches the batter.
Step 4: Combine wet and dry ingredients.
Slowly pour the wet ingredients into the bowl with the dry ingredients. Gently stir until no lumps remain in the batter. It’s essential to avoid overmixing at this stage as well, which can result in tough cupcakes. You want a smooth and homogenous batter that will rise beautifully in the oven.
Step 5: Fill cupcake liners and bake.
Spoon the batter into each prepared cupcake liner, filling about two-thirds full. This allows enough space for the cupcakes to rise without overflowing. Bake the cookies in the preheated oven for about 20-23 minutes, or until a toothpick inserted in the center comes out clean. Let them cool in the pan for five minutes before transferring to a wire rack to cool completely.
Step 6: Make the hot fudge sauce while baking.
In a small saucepan, combine the agave syrup, granulated sugar, and milk over medium heat. Stir until the sugar has dissolved and the mixture begins to bubble. This sauce will be drizzled over the cupcakes, adding an indulgent touch that mimics the flavors of hot chocolate. Once heated, pour it over the chopped semi-sweet chocolate and cocoa powder in a bowl, stirring until melted and combined.
Step 7: Finish the hot fudge sauce.
Add the cold butter, vanilla extract, and a pinch of salt to the bowl with the melted chocolate mixture. Stir until all the ingredients are incorporated and the frosting is smooth and glossy. Allow the sauce to cool to room temperature, which will help it thicken slightly, making it easier to drizzle over your cupcakes later.
Step 8: Prepare the frosting.
To make the frosting, beat the remaining granulated sugar, agave syrup, milk, melted chocolate mixture, cocoa powder, and cold butter together in a mixing bowl until smooth and fluffy. This step is vital for achieving a light and airy frosting that will sit perfectly on top of your cupcakes, mimicking the creamy texture of hot chocolate.
Step 9: Frost the cupcakes.
Once the cupcakes are completely cool, use a piping bag to beautifully frost them with the chocolate mixture. If you'd like, sprinkle with mini marshmallows or chocolate shavings for an extra touch. This step not only enhances appearance, offering a delightful visual effect, but it also adds creaminess and flavor, bringing that hot chocolate experience to life.

Elevate with Marshmallow Topping
A swirl of marshmallow frosting elevates these cupcakes to a nostalgic level, reminiscent of classic hot chocolate topped with fluffy marshmallows. Consider using mini marshmallows or a torch to toast your frosting for an added layer of texture and flavor. It's this whimsical touch that makes each bite feel like a warm hug on a cold day, perfectly completing your hot chocolate cupcakes.
Infusing Flavor with Espresso
Incorporating espresso powder in the batter may seem unconventional, but it plays a key role in deepening the chocolate flavor without overtly tasting like coffee. This blend amplifies the rich taste of cocoa, making your cupcakes more enjoyable for chocolate lovers. A dash of espresso creates an aromatic complexity that truly enhances the experience of each bite.
Perfect Pairing: Hot Fudge Sauce
The hot fudge sauce not only serves as a delightful drizzle but acts as a metaphorical cherry on top of this dessert. This luxurious addition pulls together the flavors of these cupcakes, creating a molten chocolate center that harmonizes with the cocoa cupcake. Every bite of the cupcake is delightful, especially when the warm fudge mingles with the soft cake, embodying the essence of hot chocolate.
FAQs
What if the cupcakes are too dense?
If your cupcakes turn out dense, it may be due to overmixing the batter. Ensure you mix just until combined and also make sure your leavening agents are fresh and active.
Can I use dark chocolate instead of semi-sweet for the frosting?
Absolutely! Dark chocolate will add a deeper more intense chocolate flavor to your frosting, creating a delightful contrast to the sweet cupcake base.
What can I do if the frosting is too runny?
If your frosting is too runny, you likely need to chill it for a while to firm it up. Alternatively, you can add a bit more cocoa powder to thicken the mixture.
How can I enhance the overall chocolate flavor?
Consider adding a pinch of cinnamon or vanilla extract to the batter. This can enhance the chocolate flavor without overpowering it, bringing out deeper notes.
What if my hot fudge sauce seizes up?
To remedy seizing, gently reheat the mixture over low heat, adding a little more milk while stirring to return it to a pourable consistency.
Can I substitute the sour cream with plain yogurt?
Yes, plain yogurt can be used in place of sour cream while still maintaining moisture and tanginess in the cupcakes.

These hot chocolate cupcakes are sure to be a hit, whether for a festive gathering or just a cozy evening at home. Their rich chocolate flavor and delightful texture offer a sense of warmth that resonates with everyone during colder months.
Baking them not only creates a delicious treat but also a wonderful way to share joy around the table. Enjoy every bite, and don’t hesitate to experiment with toppings and fillings to make them your own.
