Ingredients

The following ingredients have 12 Servings
  • 1 cup unsalted butter, room temperature
  • 1 cup brown sugar
  • 2 large eggs
  • 1 tsp vanilla extract
  • 2 cups flour
  • 1 tsp baking powder
  • 1 1/4 tsp baking soda
  • 1/4 tsp salt
  • 1/2 Tbs cardamom
  • 1 cup sour cream or buttermilk (I used 1/2 cup sour cream, 1/2 cup buttermilk)
  • 1/4 cup brown sugar
  • 1 tsp cinnamon
  • 1 tsp cardamom
  • 1 cup walnuts (finely chopped)

Instruction

  • Preheat oven to 350F
  • Spray a 12 cup muffin pan with cooking spray, or use muffin liners.
  • Mix the streusel in a small bowl and set aside. Make sure your walnuts are finely chopped, and that you get the lumps of brown sugar broken down.
  • Mix the flour, baking powder, baking soda, salt and cardamom in another small bowl and set aside.
  • Measure out the sour cream or buttermilk, or mix the two if you are using both, and set aside.
  • Cream the butter and brown sugar until fluffy.
  • Beat in the eggs, one at a time. Blend in the vanilla.
  • Fold the flour into the butter mixture in thirds, alternating with the sour cream/buttermilk. Just stir enough to blend, don't beat or over mix.
  • Spoon a small scoop of batter into the bottom of 12 muffin cups. Top with a teaspoon or so of streusel mix. Scoop the remaining batter on top and then top with another teaspoon of streusel, use up all the streusel.
  • Bake for about 20 minutes until a toothpick comes out clean.
  • Cool for a few minutes before removing them from the pan to a rack.
