Cut the Twix bars into small chunks and set aside.

Cream the butter and the sugar together with a mixer; add the eggs, cocoa and vanilla. Slowly add the flour so it doesn’t go everywhere.

Add the Twix chunks to the brownie batter and stir in with a spoon or spatula.

Pour the batter in a greased 9x13 pan. Drizzle the caramel topping evenly over the batter. After the caramel drizzle, take a toothpick and swirl the caramel around.

Bake for 35 minutes at 350°. Drizzle with more caramel to servel.
