Ruby Red Grapefruit Sour Cream Cake

Seeing that it’s Friday and all I thought we should celebrate with cake.

A ruby red grapefruit cake to be exact.

Last Friday a big ol’ box of grapefruit was delivered to my front door {thanks to TexaSweet}. The box came a little damaged and dented {thanks delivery man!}, but when I opened it up and saw those beauts all was forgotten. After I made this cake I squeezed one grapefruit and strained it into a glass and drank it. SO darn good!

While pending the arrival of my grapefruits I devised a plan on how I was going to go about making the cake part. I borrowed the recipe from this post and the technique from this post, did a little ingredient swapsies and *poof!* this beautiful cake {that sort of tastes a bit like Froot Loops #notevengonnalie}… was born.

ingredients
For the cake you’ll need the usual: flour, sugar, salt, baking powder, eggs, milk ,{melted} butter. You’ll also need some sour cream and two grapefruits!

sugar
Start off by measuring 1 cup of sugar and pour it into a large bowl.

grapefruit sugar
Zest the grapefruits until you have two tablespoons and then add it into the sugar bowl. Use your fingers and rub the sugar into the zest until the texture feels like wet sand.

pink grapefruit
Cut the grapefruit in half. I used a juicer and then strained the freshly squeezed grapefruit juice until I had 3 tablespoons worth.

eggs, grape fruit juice, butter and mixed
In the bowl with the grapefruit sugar; crack two eggs, add the grapefruit juice, add the melted butter and give it all a good whisk.

salt, bpowder and whisk
In a smaller bowl combine the flour, salt and baking powder. Give that a good whisk too, to break up and clumps and fluff it up a bit.

mix sour cream and milk
In a small bowl or measuring cup stir together the half cup of sour cream and the two tablespoons of whole milk. This just makes adding to the batter more simple.

whisk and pour
Alternately add a third of the dry ingredients, then a third of the sour cream mixture until it’s all incorporated. Pour the cake batter into a lined loaf pan. Bake in a preheated 350 degree oven for 45 minutes or until a tester comes out clean. Do NOT over bake!

baked cake
Let the cake cool in the pan for 10-15 minutes before removing.

run your knife
Run a knife along the edge touching the pan and then use the parchment paper to lift it out on to a wire rack to finish cooling. Now go do a load of laundry.

glaze
Sooo yeah, I made this glaze. 1 cup powdered sugar, 1 {heaping} tablespoon of sour cream and then thinned it out with some whole milk. Uhhh yeah try NOT to drink this stuff… I dare you.

glazed
Annnnnd then I drizzled it all over the cake. Boo-yah!

And devour! It’s cakes like this that I wish I had the metabolism of a twelve-year-old because I’d eat this whole thing in a nano second. Like one second there’s a beautiful cake just sitting there and then *poof!* it’s gone and the only evidence is the crumbs on my chin. Awww yeah… to be twelve again.

FOR THE GLAZE:

1 cup Powdered Sugar

1 tablespoon Sour Cream

1 to 2 tablespoons Whole Milk

Preheat your oven to 350 degrees and line an 8x5 loaf pan with parchment paper, then spray with cooking spray {I use my Misto}.

Add the two eggs, grapefruit juice and melted butter. Stir until those ingredients are incorporated.

In a separate bowl, combine the flour, salt and baking powder. Give it a good whisk to remove and clumps.

Pour the cake batter into the prepared pan and bake for 45 minutes or until a tester comes out clean. Let the cake rest in the pan for 10 minutes before running a knife along the edge and using the parchment paper to lift the cake out of the pan.

Let the cake cool completely on a wire rack. Mean while make the glaze by combining the powdered sugar, sour cream and thinning it out with the milk.

Drizzle the glaze over the cooled cake and let it sit to harden for a few minutes.

Slice and serve!

Note: TexaSweet in no way compensated me for this post. They simply sent me a shipment of their glorious ruby reds out of the kindness of their hearts and I blogged about it… it’s as simple as that. My opinions are my own and I love these grapefruits!

    You really come up with the most creative und beautiful looking desserts and meals. The next time I get my hand on some juicy grapefruit I’ll be making this! Why only have grapefruit for breakfast when you can have it in cake?!

    Sweet Heaven! I have some grapefruit coming my way next week, and I just may have to make this cake instead of eating them straight up. I think I just drooled on my keyboard.

    Hi Laurie

    I was wondering if I could just use baking spray with flour for the pan instead of the parchment paper, or is the parchment paper for this recipe.

    My mouth is watering just thinking about the red grapefruit in my kitchen — just arrived today fresh from the market. I love to peel one each morning for breakfast. That way you don’t miss a drop of juice or a morsel of pulp. Bet you can guess what I’m making in my kitchen tomorrow. The ruby red grapefruit sour cream cake! In fact, I’m going to be a good neighbor and make one for the family across the street. I’m thinking about reducing the sugar in the cake to maybe 1/2 to 3/4 cup. I really love dessert that’s not too sweet.

    Thanks for a beautiful recipe. I’m inspired. ;-)

    • simplyscratch replied: — February 21st, 2013 @ 3:53 pm

      Hi Vicki! I totally agree with you! I love grapefruits too and that’s extremely thoughtful of you to make a cake for your neighbor!

    I have now made this twice in the past week. Once using Greek yogurt rather than sour cream and it is fabulous! The only thing I have noticed is it takes at least 30 minutes more than the recipe says to bake it, but I know each oven is different. It is definitely worth the wait.

    P.S. My favorite part is mixing the sugar and grapefruit zest. :-)

    Made this yesterday and Loved it. Added a tbsp of grapefruit juice to glaze also and perhaps thats why it took a little longer to solidify .Nevertheless tasted great
    Thanks again
