To make my delicious homemade blueberry muffins, you will need the following ingredients:

1 cup	white sugar
½ cup	butter (softened at room temp)
2	large eggs
1/2 cup	vegetable oil
1 cup	sour cream
½ cup	milk or water
1 tablespoon	lemon zest (grated)
3 cups	all-purpose flour (sieve flour to get rid of lumps)
1 tablespoon	baking powder
½ teaspoon	baking soda
¾ teaspoon	salt
2 cups	Canned blueberries/fresh blueberries

Preheat your oven to a temp of 375 degrees. Then grease muffin cups, or line them with paper muffin cups

Cream butter and sugar into a large mixing bowl and mix until light and fluffy. (3 minutes max). Then add your eggs and mix well. Add the vegetable oil. Mix well. Next combine sour cream, milk, and lemon zest with butter mixture. Mix until smooth.

 Whisk your dry ingredients until combined, (flour, baking powder, baking soda, and salt).

Combine half of the flour mixture into the butter mixture.  Next, add the remaining half along with the blueberries into the batter. Fold together until just combined. Spoon batter into muffin cups carefully.

Position muffin cups in the center of the preheated oven and bake for 30 minutes or until tops of muffins are golden brown, or when a toothpick inserted into the center of a muffin comes out clean.
