Preheat oven to 350F. Spray a six mini bundt pan and flour and line a 6 muffin pan with liners.
Mix together the sugar and butter until light and fluffy in a standup mixer with a paddle attachment. Add the eggs one at a time and mix well. Add in the lemon extract and lemon zest if using. Mix in the pudding mix. Mix the flour and baking soda together with a pinch of salt. Alternatively mix in the milk, flour and sour cream, ending with the flour. Beat well for 2 min. Pour the batter into the mini bundt pan and the liners. Bake for 20-30 min. or until light golden brown and they spring back easily. Let cool and remove from pan. Mix glaze together and drizzle before serving.
