An easy and delicious double chocolate muffin-our take on a Costco Copycat.
*Do ahead of time: Set the eggs, measured sour cream and measured milk out on the counter to warm up and melt the butter and allow time to cool.
Pre-heat oven to 400℉.
Add eggs to a mixing bowl and beat lightly with a whisk.
Add in milk, cooled butter, oil, water, vanilla and sour cream. Mix well.
Add cake mix, dry pudding mix and cinnamon. Mix until just moistened.
Fold in 2 cups of the semi-sweet chocolate chips.
Fill two muffin tins (24 muffins) with cupcake liners and then, divide batter between the muffin cups.
Lightly press a few chocolate chips into the top to each cup filled with muffin batter-make sure the chocolate chips stick out-so press lightly.
Place muffin tins into the oven and immediately turn the temperature to 375℉. Bake for 15-18 minutes.
Remove from the oven and cool on a cooling rack. Enjoy these copycat muffins that are so delicious.
