7. Next beat the batter with an electric mixer on low speed for 30 seconds, scraping the bowl. Then beat on medium for 2 more minutes scraping the bowl occasionally.

9. Then after you mixed the batter, pour it into a 9" greased baking pan. Then put the pan in the oven.
10. After the batter bakes in the oven for 30-35 minutes insert a toothpick into the center of the cake. If the toothpick comes out dirty or with cake crumbs on it put the cake back in the oven for about 5 more minutes.
