Step 1: Preheat Your Oven - Start by preheating your oven to 350°F (175°C). This ensures that your cupcakes will bake evenly.
Step 2: Prepare the Muffin Tin - Line a muffin tin with cupcake liners for easy cleanup and presentation.
Step 3: Mix the Dry Ingredients - In a large mixing bowl, whisk together the all-purpose flour, granulated sugar, baking powder, salt, and malted milk powder until well combined.
Step 4: Melt the Chocolate - In a double boiler or microwave, melt the finely chopped unsweetened chocolate with the unsalted butter until smooth. Let cool slightly.
Step 5: Combine Wet Ingredients - In another bowl, combine the vegetable oil, whole milk, eggs, and vanilla extract. Whisk until blended, then pour in the melted chocolate and mix until combined.
Step 6: Combine Wet and Dry Mixtures - Add the wet ingredients to the dry ingredients and gently fold using a rubber spatula until just combined.
Step 7: Fill the Muffin Tin - Evenly distribute the batter into the prepared muffin tin, filling each liner about two-thirds full.
Step 8: Bake - Bake in the preheated oven for 18-20 minutes, or until a toothpick comes out clean.
Step 9: Cool the Cupcakes - Remove the cupcakes from the oven and let them cool for 5 minutes, then transfer to a cooling rack.
Step 10: Make the Ganache - Heat the heavy cream until simmering, pour over the milk chocolate and malted milk powder. Stir until smooth and add butter.
Step 11: Frost the Cupcakes - Once cool, frost each cupcake with the ganache.
