White Chocolate Mocha Cupcakes – take two
This month’s Cupcake Hero theme is Coffee in honor of host Laurie’s husband Jaos and his upcoming birthday (Happy Birthday Jaos!) I heard that one of their favorite treats at Starbucks is a white chocolate mocha. I already took one shot at a white chocolate mocha cupcake. I wasn’t happy with the white-chocolate-mochaness of it, so here’s my second try.
These cupcakes definitely taste like a white chocolate mocha. The cake is similar to an angel food cake with espresso powder in the batter. They have a subtle coffee flavor. I added some espresso over the top of the cupcakes to keep them moist and intensify the coffee flavor.
The white chocolate mousse didn’t bring enough white chocolate flavor to the table, so I also added a small layer of melted white chocolate. After quite a few different tries, this combination hit the white-chocolate-mocha flavor I was searching for. Hubby and I both couldn’t stop eating them!
Coffee Cupcakes – makes 30 – from Crazy about Cupcakes
12 large egg whites, cold
3 Tbsp espresso, at room temperature
1 Tbsp lemon juice
1 tsp cream of tartar
1 tsp vanilla extract
1/2 tsp almond extract
1 1/2 cups granulated sugar
1 cup all-purpose flour
1 Tbsp ground espresso beans
1/2 tsp salt
Preheat oven to 325. Insert liners into a medium cupcake pan.
In a large bowl combine the egg whites, espresso, lemon juice, cream of tartar, vanilla, and almond extract. With an electric mixer on high speed, beat until mixture is foamy with tiny bubbles, 2-3 minutes. Gradually add 3/4 cup of the sugar until the foam is creamy white. Do not overbeat.
In a separate bowl combin 3/4 cup sugar, flour, ground espresso beans, and salt.
Fold the dry ingredients into the egg mixture. Gently mix with a rubber spatula or wooden spoon until completely integrated.
Fill the cupcake liners three-quarters full. Bake for 20-25 minutes or until a toothpick inserted in the center of cupcakes comes out clean. Cool cupcakes in the pan. 
White Chocolate Mousse – from FoodNetwork.com
1 1/2 cups heavy cream
5 ounces white chocolate, coarsely chopped
1/2 cup egg whites (from about 4 eggs)
2 tablespoons sugar
In a small saucepan, heat the cream over medium heat just until it boils.
Immediately turn off the heat. Place the chocolate in a medium bowl. Pour the hot cream over the chocolate and whisk until melted and smooth. Strain into another bowl, cover, and refrigerate overnight.
The next day, remove the mixture from the refrigerator and, using a mixer fitted with a whisk attachment or a hand mixer, whip it into fluffy, soft peaks. Return to the refrigerator.
In a clean dry bowl, whip the egg whites until soft peaks form, then add the sugar and continue whipping until glossy and stiff, about 30 seconds more. Fold into the white chocolate mixture.
To assemble cupcakes:
Poke holes into the cupcakes with a fork or toothpick. Spoon about 1 teaspoon of room temperature espresso on top of each cupcake.
Melt 8 ounces of white chocolate in a double boiler. Spread about 1 teaspoon of white chocolate on top of the cupcakes.
Using a small cookie scoop or a piping bag, scoop the mousse on top of the white chocolate.
Garnish with white chocolate curls and sprinkle with cinnamon.

Hm…domes…good for cupcakes, sorta annoying for layer cakes. 🙂
I wonder if you bumped up the baking temperature a bit, if the cupcakes would have a more dramatic rise? Obviously you’d need to reduce the baking time…but you knew that. 😉
It doesn’t look like any of the white cakes I’ve made in cupcake form have had a nicely domed top, but Dorie’s Perfect Party Cake was the most rounded. It’s a great tasting cake too.
Go-tos are ALWAYS good to find. I’m going to have to try these because I am still on the lookout for a go-to white cake. They look awesome!
These look awesome! I understand your desire for that perfect dome, though.
I’m happy to have one for chocolate cake, but I wish I had more go-tos! I think part of my problem is that I rarely repeat things. I just keep trekking down that endless “to bake” list of mine… Haha
Oh my word! You sound like me talking about “go to” recipes. That is my quest in life…well, in baking anyway. AND white cake is one that I have NOT found a “go to” recipe for and believe me, I have been searching for years. Literally. I also came across Bridgette’s blog where she did the white cake comparisons and I forget which one I chose to make, but I did not care for the results at all. Sigh. I was disappointed because I was certain that I would no longer have to search. I’m still at it. I also agree with you on the dome part. I definitely want my cupcakes to have a dome on them and if they don’t, I consider them a failure – no matter how good they taste. I’m kind of obsessed with the whole doming aspect.
Well, it looks like you have possibly found your “go to” white cake recipe. I guess I will keep searching. Your look amazing. Seriously – I feel like reaching through my computer screen and eating that cupcake that you have cut in half. Yummy!
Good post! Thanks for sharing.
These are beautiful! I also like domed cupcakes, but it never works out that way.
This recipe is my go-to for white cake, too!! I’m so happy to see someone else post about it.
I love the crumb on those!
You might try starting your cupcakes at about 25 degrees more than usual, then when they just start to doom, reduce the temp back down. This has worked for me when I have had a flat top type batter.
I have always had a similar problem so I thought i would do some searching and came upon this comment…

Here is the recipe for the buttercream
Hello. I found your site off pinterest in a continuing search for the perfect white cake. I have possibly a very strange question, and i’m hoping you can help guide me here. I’m doing a birthday cake for my husband and my daughter, and I’m making it a flag inside (red and white layers w/ a blue center circle). my husband loves red velvet, so i’m hoping to do that for the red layers, but i’m having a hard time figuring out the perfect mix of flavors to do the white layers? would this recipe mix well w/ red velvet?

I think this recipe would go great with red velvet. I love the idea of a flag cake, although I’ve never made one myself.
My first cake made from scratch and this recipe made it a success. Super happy with the results. Thank you!

So glad you enjoyed the recipe! Great job in taking on the challenge of making a cake from scratch.
Hi! I found this recipe whilst searching for one to make a purple ombre layer cake for my best friend’s birthday. However, I am from the UK and whilst having US measuring cups, I don’t really know what cake flour is? I’m sorry if this sounds ridiculous but we don’t have it over here! Can I use Plain Flour instead as the recipe includes a raising agent? And is it the cake flour that gives the cake its white colour? Please help! Kindest regards, Naomi x

The white color of the cake comes from the fact that there are no egg yolks in the recipe. I have never substituted anything for cake flour, but here is what Joy the Baker has to say about it: http://joythebaker.com/2013/12/baking-101-the-best-cake-flour-substitute/
Hi, I’m baking a bday cake for my sis and I’m attempting to make the purple ombré cake too. Will be using the white cake recipe. Just wondering
1. Can I still use the same 24 cupcakes quantity to make 3 layers of 6″ round cakes?
2. Would the cake be still moist if I bake the cake 1 day ahead?
Thank u so much!
