Sometimes I get a recipe idea stuck in my head, and I have to make it. For the past week or so it has been a fresh orange layer cake, pictured perfectly in my head with its sunshine-yellow hue, tart-sweet flavor, and perfect crumb. I made one several years ago, following the recipe in The Cake Mix Doctor book. You start with a cake mix and “doctor” it up by adding fresh orange juice, zest and the usual eggs and such. I remember that cake fondly and somehow the memory of its deliciousness came back to bug me and wouldn’t leave me alone. Maybe it was because I had three oranges sitting in my fruit drawer, or maybe it was because I had leftover (bottled) orange juice sitting in my fridge, and since I don’t drink OJ these days, it felt like a challenge to use it up.
I ignored the idea for a while mainly because making a layer cake without a real occasion such as a birthday or a party seemed a little extravagant, plus there’s the fact that then there would be a whole cake in the house to eat and I wasn’t even sure if Sam would eat some. I even asked my neighbor, who loves sweets, if she would eat some and she declined. This past weekend, I finally gave in, deciding to make a smaller batch.
The thing is I really wanted a layer cake – not a single layer, not a square cake, a layer cake. What I love about layer cakes is the ratio of cake to frosting or filling, all perfectly portioned out so you can have the perfect bite. So how do you make a smaller batch? You can use smaller cake pans (which I don’t have) or you can do what I did and make one single layer and cut it into thirds (or halves) and make your fraction of a layer cake.
So I did just that. But when I went to stack my cakes, the cake was too dense and moist, and the curd filling I had made wasn’t thick enough, and the layers slipped and slid on top of each other while I desperately tried different ways to fix it. In the end I embraced the fact that it was an ugly cake, but hurrah at least I had made it! (I did not take any pictures of it…)
However, the flavor was also off. The cake I made had the flavor of too much baking soda and it was almost too dense to swallow. So a few days later I decided to try again, but this time I gave up on my layer cake dream and opted for a filled and frosted cupcake instead. The result: perfection. It is so satisfying to finally taste the thing that you craved, even if the original idea changed a little.
This time of year, citrus is at its best, which makes it the perfect time to make these cupcakes. Plus if you live in a part of the country where the earth and trees are brown and barren, the ground is white with snow, or skies are gray, these bright sunny colors arrive at the perfect time of year to add some color to your winter.
Orange Curd Cupcakes with Orange Cream Cheese Frosting
For the cake:
- 1 +2/3 cup all-purpose flour
- 1 + 1/4 cup granulated sugar
- 2 tsp. baking powder
- 1/2 tsp. salt
- 1/2 tsp. orange zest
- 2/3 cup orange juice (freshly squeezed or from a bottle)
- 2/3 cup canola oil
- 2 eggs
Preheat the oven to 375 degrees and line a cupcake pan with paper liners.
In a medium bowl, sift flour, sugar, baking powder, and salt together. Add orange zest and rub into the mixture so that the zest doesn’t clump in one spot and it infuses the dry ingredients with the orange oils.
In a separate bowl, beat eggs, oil and juice until blended. Add to dry ingredients and stir to combine, being sure to scrape the sides of the bowl with a spatula.
Divide the batter between your paper liners (should make about 14), filling no more than 3/4 full. Bake in your preheated oven for 18-20 minutes or until a toothpick comes out clean.
For the orange curd:
- 1/3 cup granulated sugar
- 2 tsp. orange zest
- 1 tsp. lemon or grapefruit zest
- 2 T. lemon or grapefruit juice
- 1/3 cup + 2 T. freshly squeezed orange juice
- 6 egg yolks
- 10 T. unsalted butter, cold
- pinch of salt
If you have a double boiler, get it out. If not, find a pot and glass bowl that fits perfectly into the top of the pot so that the bottom of the bowl does not go more than halfway down into the pot. Fill your pot with a few inches of water and bring to a boil. Make sure the bottom of the bowl is not touching the water as it boils. To the bowl add your sugar and zests and rub the zest into the sugar to release the flavor. Add the juices and whisk to blend. Turn the water down to a simmer and leave until the sugar begins to dissolve and the liquid is warmed.
In a separate bowl beat your egg yolks. Once the sugar and juice mixture has warmed, gradually add some, a spoonful at a time, to your egg yolks, whisking the egg yolks as you add (you don’t need to add all of the juice mixture). Once the bowl with the egg yolks feels somewhat warm to the touch, go ahead and add the egg yolk mixture to your glass bowl with any remaining juice and return it to the simmering water. Cook the mixture until it begins to thicken and coats the back of a spoon, 5-10 minutes. Remove from heat and add butter in small cubes, whisking to melt the butter. Taste and add a pinch salt to bring out all of the flavor.
Once all of the butter has been incorporated, put all of your curd into a medium size bowl, press a piece of plastic wrap to the surface to prevent a skin forming and refrigerate to cool. (You will have extra curd so feel free to halve the recipe or save for another use.)
For the orange cream cheese frosting:
- one 8-oz block of cream cheese, room temperature
- 1/4 cup butter, room temperature
- 2 T. fresh orange juice
- 1/2 tsp. orange zest
- 2 cups powdered sugar
Beat the cream cheese and butter in a medium bowl until light and fluffy. Add remaining ingredients and blend on low until sugar is incorporated enough to not fly everywhere. Scrape the sides and beat until well blended.
Once your cupcakes have cooled, take a small spoon and dig out a small hole in the top middle of each one, removing about 2 teaspoons of cake. (Set aside to eat later!) Fill each hole with your cooled curd. Frost with your cream cheese frosting and decorate as desired. Enjoy!
