Ingredients for Buckeye Brownie Cookies

Brownie Cookie Dough

Butter – use either salted or unsalted but take the butter out and let it warm up before using. 

Brown and granulated Sugar – keep the brownie cookie soft and sweet.

Egg – Holds the cookies together and gives them a little lift.  Let the egg warm up to room temperature. 

Corn Syrup – The corn syrup keeps the cookies from getting grainy by inhibiting the formation of large sugar crystals. 

Vanilla – use pure vanilla extract

Flour – all-purpose flour 

Espresso Powder  a little espresso powder enhances and intensifies the chocolate flavor of the cookie. 

Corn Starch- Helps keep the cookies plump, soft, and tender. 

Baking Soda – give the cookies some lift. 

Salt – Just a bit is all you need

Dutch Process Cocoa Powder –  this cocoa powder has been treated to make it less bitter than natural cocoa powder. 

Chocolate Chips – extra chocolate flavor and the richness of cocoa butter


Peanut Butter Layer:

Peanut Butter – Creamy Peanut Butter

Powdered Sugar – Adds just the right amount of sweetness to the peanut butter. The powdery texture mixes with the peanut butter leaving it smooth and creamy instead of grainy. 

Vanilla – Use pure vanilla and not imitation vanilla. It tastes better. 

Butter – Softened butter makes the peanut butter mixture easier to work with. 

Top Chocolate Layer

Chocolate chips – semi-sweet chocolate chips melted.
