In the container of a Magic Bullet or small food processor, add the walnuts, cinnamon and 2 Tbsp. Keto Sweet. Pulse to a uniform consistency. Drizzle in the butter, stir to combine and set aside.

Preheat oven to 350 F. Line a muffin pan with unbleached parchment paper liners.

In a medium mixing bowl, add the eggs, sour cream, vanilla, yeast and 3 Tbsp. Keto Sweet. Using a hand mixer, blend on medium speed to thoroughly combine.

Add the Miracle Mix and blend on medium speed for 1 minute to incorporate. You will have a thick batter.

Divide batter between muffin cups. Top with streusel.

Transfer to preheated oven and bake 20-22 minutes or until a toothpick inserted in the center comes out clean.

Let cool in the pan for 5 minutes. Then transfer muffins to a wire rack to continue cooling.
