Chocolate Blackout Cupcakes Ingredients
For the Ganache
• Semisweet Chocolate (2 ounces) – Adds richness to the ganache filling. Substitute with bittersweet chocolate for a deeper flavor.
• Heavy Cream (1/4 cup) – Helps emulsify and smoothen the ganache. Can substitute with coconut cream for a dairy-free version.
For the Cupcakes
• Bittersweet Chocolate (4 ounces, finely chopped) – Main component for ganache filling; deepens chocolate flavor. Use dark chocolate for an even richer taste.
• Dark Dutch-Processed Cocoa Powder (1/3 cup) – Provides a robust chocolate flavor and dark color. Can substitute with natural cocoa powder if Dutch-processed is unavailable but results may vary.
• Boiling Water (1/2 cup) – Activates the cocoa for better flavor extraction. Cannot be substituted as it is crucial for the recipe.
• All-Purpose Flour (3/4 cup) – Provides structure to the cupcakes. Gluten-free all-purpose flour can be used as a substitute.
• Granulated Sugar (1/2 cup) – Sweetens the batter. Brown sugar can be used for added moisture and depth.

• Fine Sea Salt (1/2 teaspoon) – Enhances overall flavor. Regular table salt can be used as a substitute.
• Baking Soda (1/2 teaspoon) – Helps cupcakes rise. Ensure it is fresh for best results.
• Sour Cream or Plain Yogurt (1/2 cup) – Adds moisture and tenderness; yogurt can be used as a substitute for a lighter texture.
• Vegetable Oil (1/4 cup) – Keeps cupcakes moist. Can be replaced with melted butter for a richer flavor.
• Large Eggs (2) + Extra Egg Yolk (1) – Provide moisture and structure. Can use flax eggs for a vegan option.
• White Vinegar (2 teaspoons) – Helps to activate baking soda for better leavening. Can be omitted but may affect rise.
• Vanilla Extract (1 teaspoon) – Adds flavor. Use pure vanilla extract for the best taste.
For the Buttercream
• Unsalted Butter (8 ounces, at room temperature) – Main ingredient in buttercream for richness; can be replaced with margarine or a vegan butter for a dairy-free version.
