Cranberry Streusel Coffee Cake

We came home from Thanksgiving travels and the cupboards were pretty much bare - I had to find something for breakfast, and found this recipe from Amandascookin.com:

Cranberry Streusel Cake

For the cake:

9 ounces (2 cups) all-purpose flour; more for the pan *I used 1 cup white whole wheat flour*

1 teaspoon baking powder

1/2 teaspoon baking soda

1/2 teaspoon ground nutmeg

*I also added 1 teaspoon ground cinnamon*

1/4 teaspoon table salt

8 tablespoons (1 stick) unsalted butter, well softened at room temperature; more for the pan

1 1/3 cups sugar

1 teaspoon vanilla extract

3 large eggs, at room temperature

1 cup plain, low-fat yogurt

1/2 cup fresh cranberries, chopped

For the streusel:

1/4 cup packed light brown sugar

2 tablespoons all-purpose flour

1/2 teaspoon ground cinnamon

2 tablespoons cold unsalted butter, cut into 4 pieces

1/4 cup chopped walnuts *I omitted these*

1/4 cup fresh cranberries, chopped

Make the cake:

Position a rack in the middle of the oven and heat the oven to 325°F. Lightly butter and flour a 9-inch-square baking pan. *I just sprayed with PAM.

In a medium bowl, whisk the flour, baking powder, baking soda, nutmeg, and salt until blended.

With an electric mixer, beat the butter, sugar, and vanilla on medium speed until well blended, about 3 minutes. Reduce the speed to medium low and add the eggs one at a time, mixing until just incorporated. Using a wide rubber spatula, alternately fold the flour mixture and the yogurt into the butter mixture, beginning and ending with the flour mixture. Add the chopped cranberries with the last addition of flour.

Scrape the batter into the prepared pan and spread it evenly. Tap the pan gently on the counter to release any air bubbles. Bake for 40 minutes.

Make the streusel:

While the cake is baking, combine the brown sugar, flour, and cinnamon in a medium bowl. Add the butter and mix, using a fork, until the ingredients are well blended and form small crumbs. Stir in the walnuts (if using) and cranberries.

After the cake has baked for 40 minutes, sprinkle the streusel evenly over the top of the cake. Continue baking until a pick inserted in the center comes out clean, another 10 to 15 minutes.

Cool in the pan on a wire rack until warm or room temperature. Cut into squares and serve.

Note: the original author of the recipe mentioned drizzling confectioner's glaze over the coffee cake; I didn't and it's still very good - both warm and cold the next morning.
