Big, buttery, fluffy & filled with chocolate chips - these bakery style chocolate chip muffins will be your new favorite.
Preheat your oven to 425F degrees and butter or line a 12 cavity muffin tin.
In a medium bowl, whisk together the flour, baking soda, baking powder and salt.
Beat the butter and sugar together until light and fluffy - about 2 minutes. Add in the eggs and vanilla and continue mixing until combined.
Turn off your mixer, scrape down the sides & fold in the sour cream and buttermilk.
Carefully fold in the flour mixture until almost combined. Then stir in the chocolate chips.
Fill your muffin tins to the very top (about a generous 1/3 cup). Optionally sprinkle with a few extra chocolate chips and coarse sugar.
Then bake at 425F degrees for 5 minutes. Turn down the oven to 375F degrees and continue baking for 13-15 minutes.
Allow muffins to cool in the pan for 5 minutes, then continue cooling on a wire rack.
