To bake the sweet potatoes, preheat the oven to 400 degrees F. Bake the sweet potatoes covered in foil paper for 40-45 minutes or until very tender.
Turn the oven to 350 degrees F if you’re going to make the muffins right after.
Prepare a muffin tin with ten muffin liners.
Whisk together almond milk, brown sugar, granulated sugar, and vanilla extract together in a medium-sized mixing bowl.
Add mashed sweet potatoes and combine.
Mix flour with baking powder and ground cinnamon.
Add them to the wet ingredients. Mix until combined.
Pour the muffin batter into ten muffin liners, and fill ¾ of each liner to get medium-sized muffins. If you’d like to have larger muffins, fill them up to the top (you’ll make less than ten in that case). Sprinkle some brown sugar on the top, if desired.
Bake the muffins at 350 degrees F for 20 minutes or until an inserted toothpick comes out clean.
Remove the muffins from the oven and let them cool on a cooling rack.
