¼ cup (60g) full-fat sour cream or greek yogurt, at room temperature
2 T full-fat milk, room temperature
2 teaspoon pure vanilla extract
⅔ cup (130g) mini semi-sweet chocolate chips
Instructions
Preheat and Prep Pan: Preheat oven to 425°F. Grease and flour a jumbo 6-count muffin pan or line with muffin liners. Set aside.
Mix Dry Ingredients: In a large bowl, whisk together flour, baking powder, baking soda, salt, cinnamon, and nutmeg.
Combine Sugars and Butter: In a larger bowl, whisk sugars, vanilla extract, and melted butter for about 1 minute. Scrape down the bowl, then add oil and egg, mixing until combined.
Add Dairy: Mix in sour cream (or Greek yogurt) and milk, blending well.
Fold in Dry Ingredients and Chocolate Chips: Gently fold dry ingredients into the wet mixture until just combined. The batter will be thick. Fold in chocolate chips.
Fill, Bake, and Cool: Fill each muffin cup to the top. Bake at 425°F for 5 minutes, then reduce to 375°F and bake for 12-13 more minutes until golden. Cool in pan for 10 minutes, then transfer to a rack to cool completely.
Notes
For any leftovers (hard to imagine you'll have much of these, though 😉 ), they can last at room temperature for about 2-3 days or a week in the refrigerator. They also freeze well for 2-3 months. Thaw before serving.
