Whenever I smell fresh from the oven baked muffins it makes me smile and these Blueberry Oat Muffins are no exception. Loaded with chopped walnuts, fresh blueberries and oats, these help start any day!
Preheat oven to 350˚F. In a small bowl mix together the topping ingredients and set aside.
In a mixer bowl add the butter and sugar and beat until creamed together well. Next add the egg, lemon zest and yogurt and mix to incorporate thoroughly - turn the mixer off.
Add the sifted flour, baking powder, baking soda, cinnamon. Mix on low speed and after incorporated, add the oats.
Carefully add the blueberries, mix lightly by hand to distribute evenly throughout batter.
Fill 12 muffin cups with batter and top with divided topping mixture. Bake for 25 minutes or until toothpick comes out clean. Let cool or eat warm, right out of the oven.
