Cream the Sugars and Butter: Beat the cooled brown butter with dark brown sugar and granulated sugar until fluffy and light, approximately 4-5 minutes.
Add Eggs and Vanilla: Introduce eggs one at a time, mixing well, then blend in vanilla extract.
Combine Mixtures: Gradually add the dry mixture to the wet ingredients, mixing until just combined.
Fold in Toffee Bits: Gently fold in the toffee bits, ensuring even distribution.
Chill the Dough: Portion the dough onto a plate and refrigerate for 1 hour.
