Mix all your dough-oat-nut ingredients together. Pour the mixture into a greased ramekin. Bake at 375°F (190°C) for 25-30 minutes. While the oats are baking, prepare the vanilla "frosting" by combining vanilla or plain yogurt, 1/2 tsp vanilla extract, 1-2 tbsp vanilla protein powder, and a dash of sweetener. Once the baked oats are done, "frost" them with the vanilla topping. Lastly, top everything with sprinkles and enjoy!
