In a saucepan, brown the butter on low-medium for 5- 10 minutes. Continually stir to avoid burning. Once brown, immediately transfer to a separate bowl and allow the butter to cool for 10 minutes.

Beat the brown butter with brown sugar & granulated sugar. Allow it to fully mix. This will be around 2 minutes.

Then add egg, egg yolk, & vanilla extract. Beat again.

In a separate bowl, whisk together all purpose flour, baking soda, & salt. Then mix into the wet mixture.

Mix in semisweet chocolate chips, crushed pretzels, & caramel pieces.

Allow the batter to refrigerate for at least 30 minutes.

Bake at 350 for 10-12 minutes.

Allow to cool on the baking tray for at least 15 minutes before transferring to a wire rack.
