Preheat the Oven: Get your oven ready for baking by preheating it to 170°C (338°F).

Zest the Oranges: While the oven heats up, prepare the oranges. Peel them carefully, removing as much of the white pith as possible (the pith can be bitter). Segment the oranges by cutting between the membranes to separate the juicy flesh.

Orange Power: In a blender, combine the segmented oranges and blend them until smooth. This creates the orange puree that will infuse your oatmeal delight with citrusy flavor.

Mix it Up: In a large bowl, combine the rolled oats, store-bought oatmeal, chopped walnuts, your chosen sweetener, oat flour, baking powder, coconut flakes, and vegetable oil. Pour in the orange puree and mix everything well until thoroughly combined.

Bake to Perfection: Transfer the oatmeal mixture to a greased baking dish. Bake it in the preheated oven for 40 minutes. Keep an eye on it – you want a toothpick inserted into the center to come out clean, indicating it's fully cooked through.

Chocolatey Glaze: While the oatmeal delight bakes, prepare the decadent yet sugar-free chocolate glaze. In a double boiler or microwave-safe bowl, melt the sugar-free chocolate bar with the additional 2 tablespoons of vegetable oil. Heat gently, stirring frequently, until smooth and glossy.

Glaze and Enjoy: Once the oatmeal delight is baked and slightly cooled, drizzle the warm chocolate glaze generously over the top. Allow the entire delight to cool completely before serving. This allows the glaze to set and the flavors to meld beautifully.
