Step 1

First, preheat the oven to 375, and line a small muffin pan with 5 liners.

Step 2

Next, make the streusel: in a small bowl, stir together all the ingredients with a fork. It will stick together and form large clumps. Set aside.

Step 3

Next, make the muffins: In a medium bowl, add the oil, sugar, and salt. Stir together very well, and then add the egg, sour cream, and vanilla extract. Stir to combine.

Step 4

In a separate small bowl, whisk together the cinnamon, nutmeg, flour, baking powder and baking soda. Add this to the wet ingredients and stir to combine.

Step 5

Finally, stir in the cranberries.

Step 6

Scoop out enough batter to fill the muffin cups half way. Add a generous tablespoon of streusel topping on top. Then, top with the remaining batter. Sprinkle the rest of the streusel mixture on top of the muffins.

Step 7

Bake for 19-22 minutes, until a toothpick inserted comes out clean with moist crumbs. Let cool in the pan for a few minutes before serving.
