Cream 1 stick of softened butter in the mixer until smooth. Then add 1 cup of sugar and mix. Add 2 eggs, 1 tsp vanilla extract, 2 tsp baking powder, and 1/4 tsp salt and mix.

In a shallow bowl, mash 3/4 cup of fresh blueberries with the back of a fork. Add to the batter and mix. With the mixer running at low speed, add 2 cups of flour and 1/2 cup of milk (a little bit of each at a time).

Fold in another 1 3/4 cups of blueberries by hand until well mixed. Then, fill the muffin tins (here I used silicone muffin cups) to 3/4 full. Sprinkle some cinnamon and sugar on top and bake until golden brown, about 25-30 minutes.

Be sure to let the muffins cool at least 30 minutes before biting into them. It's nice to have fresh blueberries on hand! Be sure to make some of these muffins when you get a chance. They will make your heart smile.
