Preheat oven to 325 degrees F and spray a 12 cup muffin tin with nonstick spray.
In a medium bowl, add all muffin ingredients and mix well. Make sure it is well combined.
Add batter to prepared muffin tins, filling about 3/4 of the way up.
Pecan Streusel
In a medium bowl, combine all ingredients for the streusel. Using a fork, combine well. Use the forks to help break the butter apart.
Add streusel to muffins tins, filling all the way to the top.
Bake for 20 minutes and let cool before frosting.
Frosting
In a small bowl, add cream cheese and sweetener and beat with a hand mixer until well combined.
Add in the heavy cream and vanilla and continue beating.
It will be thick and so you will now want to slowly add in the almond milk to get it to a drizzle consistency you want. Feel free to add more or less as needed.
