Line an 8x4-inch bread pan with parchment paper leaving an overhang for easy removal. Line the bottom with graham crackers filling the base and breaking the crackers as needed
Combine chocolate chips and coconut oil in a microwave-safe bowl. Microwave in bursts of 20 seconds stirring in between each burst for 15 seconds until melted and smooth.
Add protein powder to thawed whipped topping and fold with a spatula until integrated. Pour chocolate on top and spread in an even layer.
Add 3/4ths of the protein whipped topping mixture on top of the chocolate. Save the rest to top your pancakes or enjoy as a snack.
Top with more graham crackers and freeze until solid, at least 8 hours. Lift the bars out using the parchment overhang. Use a sharp knife to slice into 7 long bars, then cut each in half to make 14 squares. Enjoy straight from the freezer and return any leftovers right away, stored tightly covered.
Notes
Note 1: Swap in Simple Mills Sweet Thins if you want less refined sugar. Layer them and break pieces to fit.Note 2: Use any chocolate you like—milk, semi-sweet, or dark. Watching sugar? Choose a dark or refined-sugar-free bar and chop it up.
