Preheat your oven to 350°F (175°C).
In a large mixing bowl, combine the rolled oats and protein powder.
In a separate microwave-safe bowl, mix almond butter, honey, and caramel pieces. Microwave for 30 seconds or until melted. Stir well.
Add the almond milk and vanilla extract to the wet mixture. Stir until all ingredients are combined.
Slowly incorporate the wet mixture into the dry ingredients. Mix well until a dough-like consistency is achieved.
Fold in the cinnamon chips.
Spread the mixture onto a greased or parchment-lined 8x8 inch (20x20 cm) baking dish. Ensure the mix is even and smooth.
Bake in the preheated oven for about 20 minutes or until edges turn golden brown.
