Heat oven to 400 degrees F. Coat just the bottoms of 12 standard-size muffin cups or line with muffin-cup liners.
In a large bowl, whisk together flour, baking powder, and salt.
In a medium-size bowl, whisk eggs, milk, juice, sugar, oil, and zest. Stir in 1/2 cup of the chips. Make a well in flour mixture; pour in egg mixture. Stir until dry ingredients are just moistened.
Spoon 1/4 cup batter into each muffin cup. Sprinkle remaining chips on top. Bake in a 400-degree oven for 20 minutes or until toothpick comes out clean.
Remove pans to wire rack and cool for 5 minutes. Remove muffins from pan, cool completely on wire rack.
