Step 10 -While running the hand mixer on low speed, slowly add the flour mixture to the butter mixture and stop mixing just before all of the flour is incorporated.

Step 12 -Pour the batter into the prepared pan.

Step 13 -Bake until a toothpick inserted into the center comes out clean, about 35-40 minutes.
