Line a cupcake pan with a muffin liner. Set aside.
In a mixing bowl, whisk the flour, baking powder, baking soda, and salt. Set aside.
In a large mixing bowl, cream the butter with a hand mixer.
Add the brown sugar and granulated sugar. Mix until combined.

Add the flour mixture, alternating with the milk.
With your last flour addition, add the chocolate chips. Mix until all ingredients are combined. Don’t overmix.

The muffins are baked when a toothpick in the middle comes out clean of muffin batter.
Cool in the pan for 5 minutes, then carefully transfer to a cooling rack.
Notes
I will mix the wet ingredients with a hand mixer, but once I add the flour, I will use a Danish dough whisk. This way, I make sure I don’t overmix, which causes tougher muffins.Variations: milk chocolate chips, white chocolate chips, peanut butter, chocolate-covered toffee bits, or sprinkles would be great alternatives.Add some cinnamon or ginger to the batter. Remember, a little goes a long way. ½ teaspoon cinnamon and a pinch of ginger is a great start.Storage: In an airtight container at room temperature for up to 4 days. They can also be frozen for up to 3 months for maximum freshness. Just make sure they are completely cooled before freezing.Re-warm: To make them “fresh out of the oven” experience, you can warm them up in the microwave for 10-12 seconds or air fryer at 330 degrees F for 4 minutes.
