Using a hand mixer or stand mixer, start by adding the butter, vanilla extract, egg, sugar, and lemon juice to the mixing bowl.
Using a whisk attachment, fully whisk wet ingredients together until fully incorporated.
Now it's time for your dry ingredients!
Add in your salt, baking soda, and baking powder and whisk into wet ingredients at medium speed.
Switch to your paddle attachment if using a stand mixer, and add your flour 1/2 cup at a time.
For best results keep the mixer on low speed as you add our flour.
Once the flour is fully incorporated, grab your blueberries and carefully fold them into the cookie dough, try not to mash the blueberries.

Now it is time to shape your cooking dough balls, roll them into heaping 1 Tbs. ball size, and fully cover them in sugar by rolling your dough ball into your sugar for rolling.
