Prepare the Cake Batter : Preheat your oven to 350°F (180°C) and line a loaf pan with parchment paper. In a large mixing bowl, combine the ground pistachios, oat flour, gluten-free plain flour, baking powder, salt, and cardamom. Mix well. In a separate bowl, whisk together the coconut yogurt and maple syrup. Pour the wet ingredients into the dry ingredients and gently mix until well combined.
Bake the Cake : Pour the batter into the prepared loaf pan, spreading it evenly. Place the loaf in the preheated oven and bake for 30–35 minutes, or until a toothpick inserted into the center comes out clean. Allow the loaf to cool in the pan for 10 minutes before moving it to a wire rack to finish cooling.
Prepare the Frosting : Drain and rinse the soaked cashews, then add them to a blender or food processor. Add the milk of choice, maple syrup, beetroot powder (or food coloring), vanilla extract, and rose water. Blend until smooth and creamy, adding more milk if needed to achieve a spreadable consistency.
Frost and Decorate : Once the loaf is completely cooled, spread the cashew frosting over the top. Decorate with chopped pistachios and pomegranate seeds for a beautiful, vibrant finish.
Serve : Slice and serve the Pistachio Cardamom Rose Loaf. Enjoy it fresh or store it in the refrigerator for up to 3 days.
