This is a recipe I adapted from one I found at AllRecipes.com. The original recipe is for blueberry muffins. I've used this recipe with blueberries and it turned out well but I think it could use a crumb topping or sprinkle of turbinado sugar on top. As chocolate chip muffins they were good as is. If you like them really chocolatey you could add more chocolate chips.
Chocolate Chip Muffins
Adapted from AllRecipes.com
2 cups minus 4 tbsp all-purpose flour
3/4 cup sugar
1/2 tsp salt
3 tsp baking powder
3/4 cup milk
1/3 cup canola oil
1/2 cup milk chocolate chips (or 1 cup blueberries)
1 tsp vanilla powder
Heat oven to 400 F. Line 12 muffin cups with liners. In medium bowl, combine flour, sugar, baking powder, chocolate chips, vanilla powder and salt.
In a large bowl, combine milk, oil and egg. Blend well. Add dry ingredients all at once, stir until dry ingredients are moist (batter will be lumpy).
Fill cups 2/3 full. Bake for approximately 20 minutes (mine were done in 17 minutes).
