Mix the oats and protein powder in a bowl.
Stir in the milk and fat free Greek yogurt until smooth.
Add to your serving bowl/container and leave in the fridge for a few minutes while you are making the glaze.
Meanwhile to make the glaze topping, melt the white chocolate in the microwave in 15 second intervals.
When melted, stir in the cream cheese until smooth and heat for a further 15 seconds to soften the cream cheese.
Stir in the fat free Greek yogurt.
Remove the oats from the fridge and pour the glaze over spreading evenly on top.
Cover and pop back in fridge until serving (overnight or a few hours).
Top with a crumbled oreo biscuit and enjoy.
