Description
These Olympic Chocolate Muffins are a moist, richly chocolaty treat inspired by the viral Paris Olympics muffins. Generously studded with chunks of dark and milk chocolate and filled with a luscious hot fudge center, these muffins offer a decadent breakfast or snack option that combines intense cocoa flavor with a soft, tender crumb. With a resting period to develop flavor and a two-step baking process, they deliver bakery-quality results at home.
Ingredients
Muffin Batter
- 1½ cups all-purpose flour (195g)
- ½ cup Dutch Process cocoa powder (56g)
- 2 tablespoons black cocoa powder (14g)
- 2 tablespoons milk powder (10g)
- 1 teaspoon salt
- ¾ teaspoon baking soda
- ½ teaspoon espresso powder
- ¼ teaspoon baking powder
- ½ cup salted butter, melted (113g)
- ⅓ cup + 1 tablespoon buttermilk (92g)
- ¼ cup canola oil (52g)
- 1 tablespoon vanilla extract
- 2 large eggs, room temperature
- 1 cup vanilla skyr yogurt (225g), or sour cream
- 1⅓ cups light brown sugar, packed (300g)
- 4 ounces dark chocolate, chopped (115g)
- 4 ounces milk chocolate, chopped (115g)
- Chocolate chunks for topping
Fudge Center
- Hot Fudge Sauce, homemade or storebought (amount as needed for piping, about half batch for 16 muffins)
Instructions
- Prepare Hot Fudge Sauce: Prepare a batch of hot fudge sauce ahead of time if using homemade, as you will need about half a batch to fill all the muffins.
- Mix Dry Ingredients: In a large bowl, whisk together flour, Dutch process cocoa powder, black cocoa powder, milk powder, salt, baking soda, espresso powder, and baking powder until well combined.
- Melt Butter and Combine Wet Ingredients: In a medium microwave-safe bowl, melt salted butter. Whisk in buttermilk, canola oil, and vanilla extract. Then beat in the eggs one at a time until incorporated.
- Add Yogurt and Sugar: Whisk in the vanilla skyr yogurt until smooth, then whisk in the light brown sugar until fully incorporated.
- Combine Wet and Dry: Pour the wet ingredients into the dry ingredients and whisk gently until just combined with no dry streaks. Avoid overmixing to preserve muffin texture.
- Fold in Chocolate: Fold chopped dark and milk chocolate evenly throughout the batter.
- Rest the Batter: Cover the batter with a dish cloth and let it rest at room temperature for 30 minutes to develop flavors and improve texture.
- Preheat Oven and Prepare Pans: Preheat your oven to 425°F (220°C). Line a regular muffin tin with tulip parchment liners.
- Portion Batter: Using a #16 scoop (about 3 tablespoons), portion slightly heaping scoops of batter into muffin liners, filling near the rim but not overflowing. You should have enough for 16 muffins.
- Add Topping Chocolate Chunks: Generously top each muffin with 10 to 12 chocolate chunks, which will help create a decorative, textured surface.
- Bake Muffins: Bake the muffins at 425°F for 7 minutes, then reduce oven temperature to 350°F (175°C) and bake for an additional 13 to 15 minutes. Check doneness by inserting a toothpick; it should come out mostly clean, accounting for melted chocolate residue.
- Cool in Pan: Remove muffins from the oven and allow them to cool in the pan for about 15 minutes before removing.
- Fill Muffins with Hot Fudge: Using the end of a wooden or silicone spatula, poke a hole in the top center of each muffin. Fill a piping bag with hot fudge sauce, cut a ¼-inch hole at the tip, and pipe the fudge into each hole to create a luscious molten center.
Notes
- Use salted grass-fed butter for best flavor and texture results.
- Packaged chocolate chunks work better for topping than chopped chocolate as they stay on top and provide a uniform appearance; chopped chocolate tends to sink into the batter.
- If you don’t have black cocoa powder, you may substitute all Dutch-process cocoa powder, but expect slightly lighter color and less intense chocolate flavor.
- Room temperature eggs contribute to better batter emulsification and muffin texture.
- Resting the batter before baking is critical to achieving the perfect crumb and flavor development.
- You can prepare the hot fudge sauce in advance and store in the refrigerator until ready to use.
