Blueberry Lemon Curd Cupcakes

Wonderfully lemony, these cupcakes have white chocolate in the batter, lemon curd in the filling and fresh blueberries in the frosting. Simply gorgeous!

Innovate on a cupcake.

That is  Willow Bird Baking's challenge for this week.

I sat there thinking how not up to my alley this was. Just any cupcake? How do I narrow it down? Then she added baking according to the season we're on now.

I'm happy to be having a few incredible spring days. After a lot of rain and humid days, we're having clear skies, perfect weather, the kind of days you want to last and last. Really. That's the feeling.

Not a new flavor combination idea, but the fresh berries in the frosting look so pretty. I mean, cupcakes have to have some sort of prettiness to them, right?

The cake part has some white chocolate, which really makes them moist and deepens tremendously the flavor of vanilla.

Ever since I closed the coffee shop, I suddenly realized that the more I bake the more everything will just lie around the house, taking up counter space and even living room space. So I'm starting a list of happy takers of baked goods.

One of those recipients, until they get sick of eating sweet things or put on a few pounds and start seeing me as the evil baker, is one of my weavers, you know, from my now only job.

So I made half the batch the way you see them here, and the other half filled with dulce de leche and topped with melted chocolate. I didn't photograph them because they are ridiculously simple, not even a ganache involved. But it goes to show that this cake recipe admits endless flavor combinations.

Flavored cream cheese frosting.

The fresh blueberries in the frosting are made by processing them and adding a tablespoon of lemon juice and water. If you have frozen blueberries, you don't need to add liquid, the ice will melt and be perfect.

And they give the cream cheese frosting the most wonderful lilac color.

I like this frosting, I really do. The lemon curd cuts nicely through it and the extra blueberry puree spooned on top adds another sharp and fresh note.

I think they are perfect for spring. And my happy testers agreed.

Instructions

For the cupcakes:

1. Preheat oven to 350ºF. Line 24 muffin molds with paper cups.
2. Over a pot with boiling water, melt chocolate and water. Reserve.
3. In a large bowl, with an electric mixer, beat butter until smooth. Gradually add sugar and beat until light and fluffy. Add egg yolks, one at a time, a mix until well combined. Add vanilla.
4. Add dry ingredients in three additions, alternating with buttermilk in two additions.
5. In a clean bowl with dry, clean beaters, beat egg whites until soft peaks form. With a spatula add to the cake batter in two or three additions, mixing gently until no streaks of white remain.
6. Carefully fill muffin cups to ¾ of their capacity.
7. Bake for about 30 minutes, until springy and tester inserted comes out clean.
8. Let cool completely on wire rack.

For the lemon curd:

1. In a medium heavy saucepan, heat lemon juice, butter and cream, just below the boiling point.
2. In a large bowl mix to blend eggs, yolks and sugar.
3. Gradually add hot lemon mixture, mixing well.
4. Transfer the mixture back to the saucepan and stir constantly over medium heat until it thickens and leaves a path in the back of the spoon. Be careful not to burn the bottom.
5. Remove from heat, add salt and vanilla and let cool. Cover and refrigerate. It keeps for 5 days refrigerated.

For the cream cheese frosting:

1. Process blueberries with water and lemon juice. It will take a few minutes.
2. In a large bowl mix butter and cream cheese. Beat until very smooth.
3. Add 10 Tbs of the blueberry purée.
4. Add 1 cup sugar and beat well. Keep adding confectioners' sugar, ½ cup at a time until the frosting is thick enough to spread. Refrigerate for 1 hour.

To assemble cupcakes:

1. With a small spoon or melon ball scoop, take out a piece of cake the size of a small walnut. Discard.
2. Pipe or spoon some of the cold lemon curd, filling the hole completely.
3. Using a piping bag with a wide, plain tip, pipe the frosting on top of the cupcakes.
4. To serve, spoon some extra blueberry purée on top of the frosting.

Notes

Use raspberries instead of blueberries for a tangier cupcake.
