Chocolate Chip Muffins

3 c. flour
1 c. sugar
1 1/2 T. baking powder
1/2 t. salt
1 1/2 c. mini or regular-sized chocolate chips
1/2 c. butter, melted and cooled
1/4 c. vegetable or canola oil
3 eggs
1 1/2 c. milk
2 t. vanilla

1. In a large bowl, whisk together the flour, sugar, baking powder and salt until combined. Stir in the chocolate chips.
2. In a second bowl, combine the remaining ingredients and whisk until fully combined. Pour the wet ingredients into the dry ingredients and stir just until everything is moistened and combined. Be careful not to over-stir.
3. Pour into greased or lined muffin tins. Bake at 375 degrees for 12-14 minutes for a mini-muffin tin and 15-18 minutes for a regular-sized muffin tin, until fully cooked. (Use the toothpick test, if needed.)

Recipe makes 40 mini muffins and 6 regular sized or about 1 1/2 - 2 dozen regular sized muffins.
