03 - Beat in eggs, extra yolk, and vanilla for 30 seconds. Pour in oil and cocoa, mix well.

05 - Save some chips and toffee for top. Stir rest into batter.

# Notes:

01 - Store at room temp for 3 days or chilled for 5 days.
02 - Chilling makes brownies extra fudgy.
03 - Use dark chocolate chips for less sweetness.
04 - Regular cocoa powder works if no Dutch-process available.
