Making Browned Butter Blueberry Cookies can be a fun and rewarding process. Just follow these easy steps to create your batch:

1. Brown the Butter: In a medium saucepan, melt the butter over medium heat. Stir frequently until it turns golden brown and develops a nutty aroma. Remove from heat and let it cool slightly.
2. Mix Sugars: In a large mixing bowl, combine the browned butter, brown sugar, and granulated sugar. Whisk until well blended.
3. Add Egg and Vanilla: Beat in the egg and vanilla extract until the mixture is smooth and creamy.
4. Combine Dry Ingredients: In another bowl, whisk together the flour, baking soda, and salt.
5. Mix Together: Gradually add the dry ingredients to the wet mixture, stirring until just combined.
6. Fold in Blueberries: Gently fold in the fresh blueberries and chopped nuts if using.
7. Chill the Dough: Cover the bowl with plastic wrap and chill in the refrigerator for at least 30 minutes. This helps the cookies maintain their shape while baking.
8. Preheat Oven: Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.
9. Scoop the Cookies: Using a cookie scoop or tablespoon, drop rounded balls of dough onto the prepared baking sheet, leaving space between each cookie.
10. Bake: Bake in the preheated oven for 12-15 minutes, or until the edges are golden and the centers are set.
11. Cool: Remove from the oven and let the cookies cool on the baking sheet for about 5 minutes before transferring them to a wire rack to cool completely.

These simple steps will lead you to the creation of delicious cookies that are sure to be a hit!
