Ingredients
- 1 2/3 cups all-purpose flour
- 2 teaspoons baking powder
- 1/2 teaspoon baking soda
- 1 teaspoon kosher salt
- 3/4 cup unsweetened cocoa powder, divided
- 1/2 cup hot water
- 1 cup granulated sugar
- 1/3 cup vegetable oil
- 2 large eggs plus 1 yolk, at room temperature
- 2 teaspoons pure vanilla extract
- 3/4 cup sour cream, at room temperature
- 15 ounces semi-sweet chocolate chips (about 2 1/2 cups), divided
Instructions
- Preheat the Oven: Preheat your oven to 375°F (190°C). Line a 6-cup jumbo muffin tin with jumbo cupcake liners or lightly grease each cup.
- Bloom the Cocoa Powder: In a small bowl, whisk together 1/4 cup of cocoa powder and 1/2 cup of hot water until smooth. Set aside to cool slightly.
- Mix the Dry Ingredients: In a medium bowl, whisk together the flour, remaining 1/2 cup of cocoa powder, baking powder, baking soda, and salt until evenly combined.
- Prepare the Wet Ingredients: In a large mixing bowl, whisk together the granulated sugar, vegetable oil, eggs, egg yolk, and vanilla extract until smooth and well combined. Stir in the sour cream and cocoa mixture, mixing until fully incorporated.
- Combine Wet & Dry Ingredients: Gradually add the dry ingredients to the wet ingredients, stirring gently until just combined. Avoid overmixing to prevent dense muffins.
- Fold in the Chocolate Chips: Reserve 1/2 cup of chocolate chips for topping. Gently fold the remaining 2 cups of chocolate chips into the batter.
- Fill & Top the Muffins: Evenly distribute the batter among the prepared muffin cups, filling each about three-quarters full. Sprinkle the reserved 1/2 cup of chocolate chips on top of each muffin.
- Bake the Muffins: Bake for 25–30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs but no wet batter.
- Cool & Serve: Let the muffins cool in the tin for 10 minutes, then transfer them to a wire rack to cool completely. Enjoy!
Notes
- If you prefer a less sweet version, you can reduce the sugar slightly.
- For a richer taste, you can substitute the vegetable oil with melted butter.
- Feel free to add nuts or dried fruits like raisins for variation.
