Preheat the oven to 350 degrees. Add cupcake liners to the cupcake pan(s)
In the bowl of your mixer, add the dry ingredients and whisk at least 30 seconds to blend.
Skip the blueberries for now, and add the remaining ingredients to the bowl and mix on medium speed for 1 minute. Scrape the sides and bottom of the bowl and mix for 1 more minute. If you are using a hand mixer, mix for a bit longer. We will add the blueberries in the next step.
Scoop batter into the cupcake liners. Sprinkle tops with 4-5 blueberries each. Adjust number to your liking. They will sink into the cupcake as they bake- but some will stay suspended.
Bake at 350 F for about 16 minutes or until the centers spring back when lightly touched (or toothpick can be inserted and removed with just a few crumbs attached).
Remove from cupcakes from the pan as soon as you can (within a minute or two). Place on a cooling rack.
