Ingredients for Chocolate Custard Cupcakes

Chocolate Cupcakes:

  • Milk and Lemon Juice: Together, they create a homemade buttermilk substitute, adding moisture and a tender crumb to the cupcakes.
  • Cane or Castor Sugar: Provides sweetness while enhancing the chocolate flavor.
  • Brown Sugar: Adds moisture, richness, and a slight caramel flavor to the recipe. It helps make cupcakes softer and more flavorful compared to white sugar, thanks to its molasses content.
  • Oil: Keeps the cupcakes moist without overpowering the flavor. Use any neutral oil for this recipe.
  • Vanilla Extract: Rounds out the flavor profile with warm, aromatic notes that are necessary for any chocolate cupcake!
  • Cocoa Powder: The star ingredient for a rich chocolate base. Use a Dutch-processed cocoa powder for the best results.
  • All-Purpose Flour: Provides structure to the cupcake batter. You can use a gluten free all purpose flour if necessary, just make sure it has xanthan gum.
  • Baking Powder and Baking Soda: These leavening agents ensure the cupcakes rise perfectly.
  • Salt: Balances the sweetness and enhances the chocolate flavor.
  • Freshly Brewed Coffee or Boiling Water: Blooms and Enhances the cocoa flavor and creates a smooth batter. I sometimes like to use brewed coffee as it adds complexity to the flavor of the cake.

Homemade Chocolate Custard Filling:

  • Milk: Provides the base for the custard’s creamy texture and deep chocolate flavor. You can use plain whole milk or any dairy-free milk for a vegan option.
  • Cane or Castor Sugar: Sweetens the custard while balancing the bitterness of the chocolate.You can use castor sugar.
  • Dutch Processed Cocoa Powder: Enhances the rich chocolatey depth in the custard. Using a Dutch processed cocoa powder is important as its high quality will make this custard explode with a chocolatey flavor. Natural cocoa powder will also work.
  • Cornstarch: Essential for thickening the custard to create a smooth, stable filling.
  • Unsalted Butter: Adds richness and creaminess to the custard. Dairy-free butter can be used for a vegan version.
  • Vanilla Extract: Adds a hint of flavor that compliments the chocolate.
  • Dark Chocolate: Use good quality chocolate to give the custard a deep, luxurious taste.

Chocolate Buttercream Frosting:

  • Butter: The base for a rich and creamy frosting. Use dairy free butter sticks if making a vegan version of this recipe.
  • Powdered Sugar and Cocoa Powder: These create a smooth, sweet, and chocolatey frosting.
  • Whipping Cream: Adds fluffiness and a light texture, use dairy free if necessary. 
  • Vanilla Extract: Balances the chocolate flavor with a touch of warmth.

How to Make  Chocolate Custard Cupcakes?

Chocolate Cupcakes

Start by preheating your oven to 350°F (175°C) and lining a 6 or 12 cup muffin pan. Combine the milk and lemon juice to create buttermilk, then mix in both sugars, oil, and vanilla extract. In a separate bowl, sift together the dry ingredients, including cocoa powder and flour, then gradually incorporate them into the wet mixture. Finally, add boiling water or brewed coffee to the batter. Pour the batter into cupcake liners and bake for 13–15 minutes.

  • Butter: Dairy-free butter sticks or any butter of your choice.
  • Sugar: Cane sugar can be substituted with granulated sugar or castor sugar. Ensure the sugar is vegan-friendly (some sugars are processed with bone char) or use organic cane sugar.
  • Whipping Cream: Unsweetened Dairy-free Whipping Cream or Canned Coconut Cream at room temperature for the vegan version or any plain whipping cream of your choice.
