Preheat the oven to 180 degrees and grease the muffin tin (or use molds.)
Roughly chop 140g trail mix. Mix the flour with baking powder and baking soda. Mix the eggs, carefully stir in the sugar, yoghurt, oil and milk. Add the flour mixture and stir until the dry ingredients are moist. Subject the trail mix. Pour the batter into the tray. Bake on the middle shelf for 20-25 minutes. Remove and let rest in the mold for another 5 minutes. Make a glaze from powdered sugar and water and decorate the cooled muffins with the glaze and the remaining trail mix.
