Preheat oven to 350°F.
Combine the egg, honey, brown sugar, flour, oats, juice, oil, baking powder, and coffee dissolved in water. When all ingredients are well incorporated, add chocolate chips. Divide batter evenly into a muffin tin lined with 12 cupcake holders.
In a small bowl, mix the streusel ingredients by hand. Top each muffin with 1 tablespoon of streusel.
Bake for 20 minutes or until a toothpick inserted into the center of a muffin comes out dry.
These muffins freeze very well.
Chef’s Note: Customize this muffin to your specific taste. Add cinnamon instead of the coffee, or walnuts or raisins instead of the chocolate chips. It’s all up to your imagination.
