These wonderful muffins are sweetened with brown sugar and made all in one bowl. They are moist, delicious, and tasty on their own or with butter and jam!
Spray 12 muffin cups with cooking spray. (Or use muffin liners.) Preheat your oven to 400 degrees.
In a large bowl, beat the melted butter, oil, brown sugar, and vanilla just until creamy. Beat in the egg and milk.
Stir in the flour, baking soda, and salt just until there are no streaks of flour.
Divide the muffin batter evenly between the muffin cups.
Bake at 400 degrees for 12 minutes. Turn the heat down to 350 degrees, and bake for another 6-8 minutes, or until a toothpick inserted in the center comes out clean.
Let the muffins cool in the pan for 5 minutes, then remove and let cool on a wire rack.
Notes
I like to make the batter in a glass bowl so I can melt the butter in the bowl without dirtying another dish.
If your flour is lumpy, either sift or whisk it with the soda and salt in a seperate bowl before adding.
Muffins can be stored in an airtight container at room temperature for 3-4 days. You can also freeze them for up to 3 months.
