In a large mixing bowl, combine dairy-free yogurt, peanut butter, vanilla protein powder, vanilla extract, and unsweetened chocolate chips. Mix thoroughly until smooth.

In a separate bowl, whisk together oat flour, vanilla protein powder, dairy-free milk, maple syrup, and additional chocolate chips until thick and cookie dough-like.

Layer 2 tablespoons of yogurt mixture into the bottom of cups followed by 1-2 tablespoons of cookie dough. Repeat until all mixtures are used.

Place the cups in the freezer for at least 4 hours until fully set.

Let the cups thaw at room temperature for 5-10 minutes before serving.
