Ingredients
Method
Step 1: Preheat the Oven
- Preheat your oven to 425°F (220°C).
Step 2: Prepare Wet Batter
- In a bowl, combine melted butter with granulated sugar and brown sugar.
- Add neutral oil and mix well for 2–3 minutes.
- Crack in the eggs and whisk for 3–4 minutes until the mixture is pale and fluffy. Stir in vanilla bean paste.
- Add buttermilk, sour cream, and dissolved espresso powder. Whisk for an additional 2–3 minutes. Set aside.
Step 3: Prepare Dry Ingredients
- In a separate bowl, whisk together all-purpose flour, baking powder, and baking soda until evenly combined.
Step 4: Combine Wet and Dry
- Gradually add the dry ingredients into the wet batter.
- Add both types of chocolate chips and gently fold until just combined. Avoid overmixing.
Step 5: Rest the Batter
- Let the batter sit untouched at room temperature for 30 minutes.
Step 6: Prepare Muffin Tins and Bake
- Line muffin tins with parchment paper or muffin liners.
- Divide the batter evenly among the tins. Optionally, sprinkle extra chocolate chips on top.
- Bake at 425°F (220°C) for 5 minutes. Then, without opening the oven door, reduce the temperature to 375°F (190°C) and bake for an additional 15 minutes.
Step 7: Check and Cool
- Insert a toothpick into the center of a muffin — if it comes out clean, they’re done. Let the muffins cool completely before serving.
Notes
- Dissolving espresso powder enhances chocolate flavor without adding a coffee taste.
- Resting the batter helps develop better texture and rise.
- Swap sour cream for Greek yogurt or buttermilk for slight variations in moisture.
- Add nuts or dried fruit for extra texture.
