Melt butter and baking sqaures in a microwave safe bowl. In the mixing bowl, cream melted butter and chocolate mixture. Add in sugar and vanilla and beat until fluffy, about 2-3 minutes. Add in eggs, beating one at a time. Add flour and stir just until combined. Fold in cookie crumbles.
Pour into greased 9 x 13 baking dish (I used a 8 x 8 square cake pan). Bake for 35-45 minutes, or until just barely done. Cool before frosting.
*I changed this recipe slightly from my other brownie posts, so if you have recently tried it, try adding 2 more eggs!
Frosting
Mix butter and powdered sugar together, adding sugar gradually to the mix. Add vanilla. Mix in milk, adding more if needed. Continue to add milk and sugar until it reaches the desired consistency. Crush Oreos and fold them into the frosting.
