01 - Place buckwheat groats in a fine-mesh sieve and rinse thoroughly under cold running water.
02 - In a medium saucepan, combine rinsed buckwheat groats, water, milk or plant-based milk, ground cardamom, vanilla extract, and salt. Stir gently to incorporate.
03 - Bring the mixture to a boil over medium-high heat. Reduce heat to low, cover, and simmer for 15 minutes, stirring occasionally, until groats are tender and most liquid is absorbed.
04 - Remove saucepan from heat. Stir in maple syrup. Cover and let rest for 5 minutes to allow flavors to meld.
05 - Divide the buckwheat mixture between serving bowls. Top with fresh berries, banana slices, chopped nuts, and coconut flakes if using. Drizzle with additional maple syrup if desired.
06 - Serve immediately while warm.
