If using frozen cranberries, let them sit on the counter while getting things ready.
Preheat the oven to 350 degrees F.
Grease or line a 9x13 pan with parchment paper.
Make the batter
Beat together the sugar and butter until light and fluffy, 2-3 minutes.
Add one egg at a time, incorporating each before adding the next. (As you add ingredients, scrape down the bowl as needed).
Mix in the yogurt and vanilla.
Add the flour and baking powder on low speed, just until incorporated.
Clean off the beaters and fold in the cranberries and white chocolate chips by hand.
The dough will be very thick and hard to stir. Stir well to incorporate all the ingredients.
Bake
Press the dough into the prepared pan.
Put the pan on the middle rack of the oven, away from the sides of the oven.
Bake for 50-60 minutes in a 9x13 pan, or until a toothpick inserted in the center of the cake comes out clean.
Set the pan on top of a cooling rack and let cool before cutting and serving.
Serve
Top with whipped cream, powdered sugar or icecream (or nothing at all).Devour.
Notes
If using a stand mixer, use the paddle attachment.Test the cake for doneness with a toothpick inserted in the thickest part. It should come out clean.Room temperature eggs are easier to incorporate into the batter and lessen the bake time for your cake.If you want to be fancy, sprinkle some sparkling or natural sugar over the top of the cake before baking.A dusting of powdered sugar is great at serving time.How do I store my cranberry cake?You can store this cake in the pan, with its pan cover, at room temperature for a few days, or you can wrap it well with plastic wrap without a cover. To freeze, let it cool completely, wrap it (in or out of the pan) in a double layer of plastic wrap and then a layer of aluminum foil. Label and use within a few months.Can I use frozen cranberries?Feel free to enjoy this cake all year round by using frozen cranberries. If you do use frozen cranberries, make sure to thaw them completely before adding them into the batter, and just a heads up - the cranberries are likely to tint your batter pink.Can I use dried cranberries?I do not recommend using dried cranberries. This cake is very sweet and that sweetness is offset by the tart cranberries. The fresh (or frozen) cranberries add to the moisture of the cake. Substitutions/AdditionsAlmond extract can be used instead of vanilla extract if you prefer.Add a little orange zest to the batter if you have an orange handy!The plain yogurt can be replaced with vanilla yogurt, but be aware that it will add more sweetness to the cake. You could use sour cream if you prefer.This cake tastes great with chopped pecans or walnuts!
