Equipment Breakdown
Before you dive into the baking, gather the necessary equipment to streamline the process:
- Mixing bowl: A large bowl is essential for mixing all your ingredients together.
- Whisk or spatula: You’ll need this for mixing and ensuring there are no lumps in your batter.
- Muffin tin: A standard muffin tin will work perfectly for baking your cupcakes.

The Method for One-Bowl Chocolate Cupcakes

Now that you have your ingredients and equipment ready, let’s get into the step-by-step process of creating these luscious One-Bowl Chocolate Cupcakes.
Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). This allows for even baking, giving you that perfect rise and texture.
Step 2: Prepare the Muffin Tin
Line your muffin tin with parchment liners. This will not only make for easy cleanup but also ensure your cupcakes come out flawlessly.
Step 3: Melt Chocolate and Butter
In your mixing bowl, combine the unsalted butter and semi-sweet chocolate chips. Pour in the very hot coffee or hot water. Mix until everything is melted and combined into a smooth mixture. The heat from the liquid will help the chocolate and butter meld beautifully.
Step 4: Add Eggs and Sugar
Once your chocolate mixture has cooled slightly, add in the eggs, egg yolk, and granulated sugar. Whisk until everything is well combined and smooth. This is where the magic starts to happen!
Step 5: Incorporate Vanilla
Add the vanilla extract to the mixture and stir well. The aroma of vanilla will enhance the chocolate flavor, making your cupcakes even more delightful.
Step 6: Mix Dry Ingredients
Next, sprinkle the all-purpose flour, baking soda, baking powder, cocoa powder, and salt over the wet ingredients. Use a spatula or whisk to gently fold the dry ingredients into the batter. Be careful not to overmix; a few lumps are perfectly fine.
Step 7: Add Sour Cream and Oil
Now, it’s time for the sour cream and oil. Gently fold them into the batter until just combined. The sour cream will add moisture and richness, while the oil contributes to a tender crumb.
Step 8: Fill Muffin Tin
Using a scoop or spoon, fill each muffin liner about 2/3 full with batter. This allows room for the cupcakes to rise beautifully.
Step 9: Bake
Place the muffin tin in the preheated oven and bake for 18-20 minutes, or until a toothpick inserted in the center comes out clean. Keep an eye on them towards the end to avoid overbaking.
Step 10: Cool
Once baked, remove the cupcakes from the oven and allow them to cool in the muffin tin for 5 minutes. Then, transfer them to a wire rack to cool completely before frosting.
Holiday & Seasonal Touches

These One-Bowl Chocolate Cupcakes can be adapted to fit any holiday or season:
- Valentine’s Day: Top with pink or red frosting and heart-shaped sprinkles.
- Halloween: Decorate with orange frosting and spooky-themed sprinkles.
- Christmas: Use peppermint extract in the frosting and garnish with crushed candy canes.
- Birthday: Add colorful sprinkles or edible glitter for a festive touch.
Missteps & Fixes
Even experienced bakers can run into issues. Here are some common missteps and how to fix them:
- Cupcakes overflowed: Make sure to fill each liner only 2/3 full to allow space for rising.
- Dry cupcakes: Avoid overmixing the batter and check for doneness a minute or two earlier than the suggested time.
- Frosting too runny: If your frosting is too thin, add more confectioners’ sugar a tablespoon at a time until desired consistency is reached.
- Frosting too thick: Add a splash of half and half to loosen it up.
Make Ahead Like a Pro
Want to get a head start on your baking? Here’s how to make ahead:
These One-Bowl Chocolate Cupcakes can be baked and stored in an airtight container for up to 3 days at room temperature. If you want to prepare the batter ahead of time, cover the mixing bowl with plastic wrap and refrigerate for up to 24 hours. When you’re ready to bake, allow the batter to come to room temperature before filling the muffin tin.
