Preheat oven to 325 ˚F and lightly grease or use paper liners in a 12-cup muffin pan.
In a large bowl, mix together buckwheat flour, flax meal, baking powder, baking soda, cinnamon, allspice, and nutmeg.
In a smaller bowl whisk together eggs, almond milk, honey and applesauce. Combine ingredients to the dry ingredients and mix well.
Fold in blueberries, cacao nibs and walnuts.
Fill muffin cups evenly and bake 15-20 minutes. To test that muffins are baked thoroughly, insert a toothpick into the middle of muffin, if it comes out clean they are done.
While muffins are baking make the glaze. In a small bowl mix together all the ingredients for the glaze until smooth.
Cool the muffins for 10 minutes. Drizzle muffins with glaze just before serving.
