I love love love the gingerbread muffins at Jason's Deli, so I googled to get a recipe that would come close, & it did... although not as amazingly yummy as the little ones at Jason's, these muffins are pretty good (especially with butter, or if you're at our house, "I can't believe it's not butter!").
1/2 cup sugar
2 1/2 cups flour
1 1/2 tsp baking soda
1 tsp cinnamon
1 tsp ginger
1/2 tsp salt
1/4 tsp nutmeg
1 cup chopped nuts (I did not put nuts, I close-to despise them in my food)
1 cup molasses (I used regular)
1 cup buttermilk
1/2 cup melted butter
Preheat oven to 350 degrees. Butter muffin tins or line with cupcake papers. Combine sugar, flour, soda, cinnamon, ginger, salt, nutmeg and nuts in a bowl. In a separate bowl, mix egg, molasses, buttermilk and melted butter, and add to the dry ingredients. Stir until just blended. Spoon into muffin tins and bake 20-25 minutes. Test with a toothpick; muffins are done when it comes out clean. Can also be served warm with whipped cream or ice cream as a dessert.
