I like to make the brownie and blondie layers at the same time since the ingredients and steps are almost identical: set the butter in a heatproof bowl and melt it. Whisk in the sugar, salt and vanilla. Give it a really good whisk so that the mix is nice and smooth then add the egg to the blondie bowl and the eggs to the brownie bowl (the brownie batter will be lighter in color due to the extra egg).

Add the flour to the bowls and the cocoa to the brownie batter, whisk well.

Spread the brownie batter over the prepared pan. Place about 9 oreo cookies and press them a bit so they sink into the brownie batter. Sprinkle the chocolate chips on top.

Now spread the blondie layer on top and add the peanut butter cups, don’t worry about pressing these in.

Bake for about 40 minutes until puffy in the center and it has fallen after rising, if you find it’s over browning before it’s puffing cover it with foil so the center will cook.

Sprinkle flaky sea salt over the bars and allow to cool fully before slicing.
