Prepare the Oatmeal: In a small saucepan, combine the oatmeal with water. Bring to a simmer and cook the oatmeal according to package instructions until soft and creamy. If you prefer a thinner consistency, you can add more water.

Flavor the Oatmeal: Once the oatmeal is cooked, remove it from heat. Stir in the instant coffee and cocoa powder until completely dissolved and mixed into the oatmeal. The coffee and cocoa will give the oatmeal a rich, tiramisu-like flavor.

Layer the Tiramisu: Grab a serving glass or bowl. Begin by layering half of the coffee-flavored oatmeal at the bottom. Next, slice the banana and place a layer of banana slices over the oatmeal.

Add Yogurt: Spoon half of the yogurt over the banana layer. The yogurt acts as a healthier substitute for the traditional mascarpone cheese layer found in tiramisu, giving the dish a creamy texture without the extra fat.

Repeat Layers: Repeat the layers with the remaining oatmeal, banana slices, and yogurt, creating a beautiful layered effect reminiscent of classic tiramisu.
