Gingerbread coffee cake muffins

Start by preheating your oven to 350F. In a large bowl, cream together your butter and sugars. Once creamed, add in your Greek yogurt and milk. Mix well and add in your egg. In a separate bowl, add your dry ingredients and mix. Add your dry ingredients to your wet ingredients and fold to combine. Place your batter in a lined muffin tin. In a separate bowl, add all your ingredients for your streusel topping and mix with your hands until a crumbly texture forms. Top your batter with streusel and place in the oven for 25 minutes. While your coffee cake muffins are baking, make your icing and set to the side. Let your cake cool for 20 minutes then ice and enjoy!
