Measure out the water and pour it into a bowl. Add the oats, half of the applesauce, and 1/4 of the peanut butter.

Mix the ingredients together well until you have a smooth, homogeneous mixture.

Divide the mixture among deep bowls and cover them with plastic wrap. Leave the bowls in the refrigerator or a cool place for 1 night (about 8 hours), so the oats can soak and soften.

After the soaking time, take the bowls and stir in the semi-skimmed milk so everything is well combined.

Add the rest of the applesauce and the remaining peanut butter to the mixture in each bowl.

Cut the banana into pieces and place them on top of the mixture.

Sprinkle the whole thing with trail mix for extra crunch. Serve cold. Enjoy!
