I made a few changes to make these five stars. I increased the Bailey's to milk ratio, making it half a cup each. I increased the brown sugar a tad. I used 1 packet of Starbucks Via for the instant coffee and I used 1/4 cup canola oil instead of the butter. I baked them at 400 for about 15 minutes and they were perfect. Love the powdered sugar on top.
Very good muffins. I love the texture of them I used 1/2 cup melted butter and cut the instant coffee to 3 tsp just right for us. I love the walnuts and powdered icing sugar as a topping. I could taste the richness the baileys added to the muffin. I got 11 nice sized muffins which were baked at 375 for 14 minutes. Made for the Kaffee Klatsch in the cooking photo fourm.
