Ingredients
Dry Ingredients:
-
1 cup (120g) all-purpose flour
-
½ cup (45g) unsweetened cocoa powder (natural or Dutch-process)
-
¾ cup (150g) granulated sugar
-
1 tsp baking soda
-
½ tsp baking powder
-
½ tsp salt
-
½ tsp espresso powder (optional for deeper flavor)
Wet Ingredients:
-
½ cup (120ml) neutral oil (like canola or vegetable)
-
2 large eggs (room temperature)
-
½ cup (120ml) buttermilk (or milk + 1 tsp vinegar)
-
½ cup (120ml) hot water
-
1 tsp vanilla extract
Optional Add-ins:
-
½ cup mini chocolate chips (for double chocolate variation)
Instructions
1️⃣ Prepare the Batter
• Preheat your oven to 350°F (175°C) and line a 12-cup muffin tin with cupcake liners.
• In a large mixing bowl, whisk together flour, cocoa powder, sugar, baking soda, baking powder, salt, and espresso powder.
2️⃣ Add Wet Ingredients
• Add the oil, eggs, vanilla extract, and buttermilk to the dry ingredients.
• Mix until just combined—do not overmix.
3️⃣ Incorporate Hot Water
• Slowly pour in the hot water while whisking. The batter will be thin; this helps create a moist texture.
• Fold in mini chocolate chips if using.
4️⃣ Fill and Bake
• Divide batter evenly among the liners, filling each about ⅔ full.
• Bake for 18–20 minutes, or until a toothpick inserted in the center comes out clean.
5️⃣ Cool and Frost
• Let cupcakes cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.
• Frost with your favorite buttercream or cream cheese frosting.
Notes
-
Room Temperature Eggs & Buttermilk help the batter emulsify better, creating even rise and texture.
-
Don’t skip the hot water—it activates the cocoa powder and loosens the batter for a tender crumb.
-
For a vegan version, replace eggs with flax eggs and use non-dairy milk + lemon juice.
-
Use natural cocoa for a classic flavor or Dutch-process cocoa for a darker, richer profile.
-
To freeze, wrap unfrosted cupcakes individually and freeze for up to 2 months.
