These don't sound like the pinacle of good health I will admit, but these are a good example of how making your own can have significant benefits as well as being lower in calories than store-bought muffins.
I made these to take with me whilst travelling around Iceland. I went for Peanut Butter-based muffins because of the high protein content as well as fibre contained in the spread. Oats release energy slowly, over a number of hours and the ones I used have added bran so again, very high in fibre. Organic skimmed milk is a good source of calcium whilst being low in fat and dark chocolate contains anti-oxidants and sweetens the muffins.
The other benefit? If you go for a muffin in say Costa coffee or Starbucks, you will be looking at 500kCal for a snack... these are delicious, have ingredients with proven health benefits and... less than 300kCal.
100g Caster Sugar
50g Oats with added bran (I would recommend the 'Essential Waitrose' ones)
200ml Skimmed Milk
65g Peanut Butter
1/4 tsp Cinnamon
1/4 tsp Nutmeg
2 tsp Baking Powder
Cream the peanut butter and sugar together then fold in the flour, oats, and baking powder. Add the milk and egg and spices and mix until all combined. Spoon into six giant muffin tins and bake at 175 degrees for approx 35 mins.
