First, preheat your oven to 425 F and spray a muffin pan with non-stick spray, or line with muffin liners.

For the streusel mix together 1/4 cup of brown sugar, 1/2 teaspoon of ground cinnamon and 2 tablespoons of all-purpose flour in a small bowl. Then add 1 tbsp of butter and mix until crumbly. Set aside.

Whisk together 2 cups of all-purpose flour, 2 teaspoons of baking powder, 1 teaspoon ground cinnamon, 1/4 cup brown sugar, and 1/2 cup granulated sugar. Set aside.

Mix 1 egg, 1/3 cup of margarine or butter melted, 1 teaspoon vanilla extract, and 3/4 cups of milk. I like to use my 4-cup measuring cup for this, for easy mixing and pouring. Then add to you dry ingredients and mix until just combined. Fold in 3/4 cups of raisins.

Divide batter in prepared muffin pan about 2/3 full. Sprinkle about 1 teaspoon of streusel on top of each muffin.

Bake in the oven for 5 minutes, then reduce temperature to 350 F and bake for an additional 10-15 minutes or until a toothpick inserted in the centre comes out clean. Let cool for 10 minutes in the pan before removing onto a wire rack to cool completely. Enjoy!
