1 cup Semisweet Chocolate Chips, ¾ cup White Chocolate Chips
Cover with plastic wrap or a clean dish towel and let rest for 30-60 minutes.
Preheat oven to 425℉/220℃ and line two muffin pan with liners. You want to line every other muffin hole, so you're baking 6 muffins at a time. This will give the muffin tops more space to rise.
Fill each muffin cup with muffin batter until it's just over ¾ full.
Bake at 425℉ for 5 minutes, then decrease temperature to 350℉/175℃ for 15-18 more minutes.
Let the muffins cool in the pan for 10 minutes before removing to a wire cooling rack to cool completely. For that bakery style look, as soon as they come out of the oven I like to press chocolate chips on top of the muffins.

Notes
My recipes have been developed and tested in cups and metric grams. I highly recommend using a weighing scale and measuring out your ingredients the metric way. Just click on 'METRIC' above the ingredients. Oil: use a neutral oil like sunflower oil, vegetable oil or canola oil. Sour Cream: you can swap out sour cream for buttermilk or full fat yogurt. Chocolate Chips: you can use mini chocolate chips or regular chocolate chips. Swap out white chocolate chips for milk chocolate or peanut butter chips. Cocoa Powder: I recommend using Dutch-processed cocoa powder. Salt: If you don’t have kosher salt, halve the amount of salt called for in the recipe. 1 teaspoon kosher salt = ½ teaspoon fine salt. Please note I am using Diamond Crystal kosher salt and not coarse kosher salt (like Morton salt) which is far too salty for this recipe. Storage: keep the muffins in an airtight container in the fridge for up to 4 days.
