Add 2 cups cottage cheese, 1/4 cup maple syrup, 1 teaspoon vanilla extract, 1/4 teaspoon salt, and 1 scoop vanilla protein powder to a blender or food processor. Blend until completely smooth and creamy, about 1-2 minutes.
Line an 8-inch square pan with parchment paper, leaving some overhang for easy removal. Arrange 9 graham cracker squares in a single layer at the bottom of the pan, breaking pieces to fit if needed.
Combine 1/2 cup chocolate chips and 1 tablespoon coconut oil in a small glass bowl. Microwave in 30-second intervals, stirring between each interval, until melted and smooth. Pour the chocolate mixture over the graham cracker layer and spread evenly.
Spread the cottage cheese mixture evenly over the chocolate layer, smoothing the top with a spatula. Top with the remaining 9 graham cracker squares, pressing gently to adhere.
Cover the pan with plastic wrap or foil and freeze for 2-3 hours, or until completely firm. The ice cream will freeze solid, which is normal for cottage cheese-based ice cream. Remove from freezer and let sit at room temperature for 10-15 minutes to soften to the perfect consistency. Cut into squares and serve immediately.
