Step 1
Line an 8 inch square baking pan with parchment paper, then spray with baking spray. Set to the side.
Step 2
Chop up chocolate sandwich cookies in a small food chopper or place them into a well-sealed plastic bag and coarsely crush them into small broken pieces using the backside of a wooden spoon. Set to the side.
Step 3
Chop up your white chocolate bars into small-medium size pieces with a large cutting knife and place it, along with the marshmallow creme into the bowl of a stand mixer. You can substitute the white chocolate bars for white chocolate chips, if needed.
Step 4
In a medium saucepan, melt the unsalted butter, Domino® Golden Sugar, heavy cream, vanilla extract, and salt over medium-high heat, continually stirring until the mixture comes to a full boil.
Step 5
Insert a candy thermometer into the saucepan with the mixture and while continuing to stir, let the mixture boil until it reaches the “soft ball stage”. If you do not have a candy thermometer, boil and stir for an additional 5-6 minutes. Remove from heat.
Step 6
Immediately pour the hot mixture over the top of the white chocolate and marshmallow creme.
Step 7
On a low-medium setting of your stand mixer, blend the fudge mixture until it is smooth and creamy. Using a spatula, fold in the crushed chocolate sandwich cookies.
Step 8
Pour the cookies and cream fudge mixture into the prepared 8 inch square pan. Even out the top, then top with additional crushed chocolate sandwich cookies (optional).
Step 9
Place into the refrigerator uncovered to set for a minimum of 4 hours or overnight.
Step 10
Cut into equally sized squares and enjoy!
