Step 1

Preheat an oven to 350F and place 9 silicone baking cups on a baking sheet or spray a muffin tin with nonstick cooking spray. Set aside.

Step 2

Mix the dry ingredients for the muffins together in a large bowl. In a separate bowl, whisk together the egg, milk, and apple sauce together before adding to the dry ingredients. Stir the muffin batter until smooth.

Step 3

Fill each baking cup 3/4 full with the muffin batter. Set aside.

Step 4

Add the butter, walnuts, oats, and Swerve brown to another bowl and stir together before adding to the top of each baking cup.

Step 5

Bake for 25-30 minutes until a toothpick or knife comes out clean. Transfer the muffins to a wire rack to cool.

Step 6

For the glaze, mix the Swerve confectioners and water together and drizzle over the top of the cooled muffins.
