First, preheat oven to 350ºF and spray a muffin tin with nonstick cooking spray. Alternatively, you can line the tin with muffin liners.
Next, place dry ingredients into a large bowl and mix to combine. Set aside.
Next, place butter in a small saucepan. Turn heat to medium/high to fully melt the butter. When the butter begins to caramelize, turn the heat off let sit in the pan until all butter has browned.
Add browned butter into the dry ingredients along with the rest of the wet ingredients.
Mix to combine and then transfer the batter into the muffin tin. Each muffin should be about ¾ of the way full.
Bake at 350ºF for 20-23 minutes.
Let cool for 5 minutes before transferring to a cooling rack to fully cool.
