Maple Brown Sugar Oatmeal Muffins are packed with warm fall flavors in every bite! Moist, hearty, covered with crumbs, and drizzled with a sweet glaze, these muffins are a must-bake for the season!
Preheat the oven to 400 F. Line a 12-cup muffin tin with paper liners.
Combine the oats and milk in a large bowl.
Add the maple syrup, oil, brown sugar, and eggs. Mix until combined.
Stir in the flour, baking powder, cinnamon, baking soda, and salt just until combined. The batter will be wet. Add chopped nuts, if using, and stir to mix.
Divide the batter evenly into the prepared muffin pan.
Make cinnamon crumb topping (see below). Sprinkle it over the top of all the muffins. Be generous as we all love our crumbs.
Bake for 7 minutes then lower heat to 350°F and bake another 11-14 minutes, or until a toothpick inserted in the center comes out clean.
Let the muffins cool in the muffin pan for 5 minutes. Remove to wire rack to finish cooling.
Cinnamon Streusel Topping
Combine all the ingredients, except powdered sugar, in a medium bowl. Cut the butter in with a pastry cutter then use your fingers to mix until the mixture resembles crumbs.
Sprinkle on top of each of the muffins before baking.
Maple Icing
Whisk all the glaze ingredients together until smooth. If it looks too thick to drizzle add more half and half, if too thin add a little more powdered sugar. Set aside until the muffins have cooled completely.
Sprinkle the cooled muffins with powdered sugar then drizzle the glaze over all. To make it easy to drizzle, add the icing to a small sandwich bag, cut the corner, then squeeze and drizzle. Let the muffins sit until the icing sets.
