1 3/4 cups all-purpose flour
1/3 cup brown sugar
1 tablespoon baking powder
1/4 teaspoon salt
1/2 cup chopped pecans
1/2 cup butter, melted
3/4 cup milk
2 tablespoons instant coffee powder
1 teaspoon vanilla extract
1 egg
1/8 cup brown sugar
2 tablespoons chopped pecans

Preheat oven to 375 degrees F (190 degrees C). Lightly grease 10 muffin cups.

In a large mixing bowl, combine flour, 1/3 cup brown sugar, baking powder, salt and 1/2 cup chopped pecans. Add melted butter, milk, instant coffee, vanilla extract and egg. Mix until all of the dry ingredients are absorbed. Fill the prepared muffin cups 2/3 full.

Combine the remaining brown sugar and pecans, sprinkle over the tops of the muffins. Bake for 18 to 20 minutes, or until a wooden pick inserted into the center of a muffin comes out clean.
