Hello!! So I know I said earlier this week that I would be sharing a delicious peanut butter torte recipe for the cake I had baked for a friend’s birthday, but I was looking through all of my files and I realized I never shared this cake with you yet. The photo quality is horrible, partly because of lack of skill and partly because I hastily took a photo under poor lighting conditions in front of everyone so you could see the inside.
All that aside, this cake was delicious but it took a surprisingly long time to make. I don’t think it helped that I chose to do a complicated basket weave design on the cake that took a good chunk of time, but by the end of the day I was actually so tired.
Anyways, this cake was for my beautiful housemate, Kelli’s birthday which was a few weeks ago and we all enjoyed this cake very much 🙂
Lemon Poppy Seed Cakes with Raspberry Curd Filling
For the cake:
2 1/3 cups cake flour
2 3/4 tsp. baking powder
1/4 tsp. salt
1 1/2 tbsp. poppy seeds
5 large egg whites, at room temperature
1/4 tsp. cream of tartar
1 1/2 cups sugar
2 tbsp. finely grated lemon zest
12 tsbp. unsalted butter, at room temperature
1 cup whole milk
For the raspberry curd:
8 tbsp. unsalted butter
1 pint ripe raspberries or 1 12-oz. package frozen raspberries, thawed
5 large egg yolks, lightly beaten
3/4 cup sugar
Pinch of salt
2-3 tsp. fresh lemon juice
For the lemon buttercream frosting:
16 tbsp. unsalted butter, at room temperature
2 tbsp. finely grated lemon zest
3 cups sifted confectioners’ sugar
3 tbsp. fresh lemon juice
Fresh raspberries, for garnish
To make the cake, position a rack in the middle of the oven and preheat the oven to 350 degrees F. Butter and flour two 8″ round cake pans. Whisk together the flour, baking powder, salt, and poppy seeds in a bowl; set aside. In the clean, dry bowl of an electric mixer fitted with the whisk attachment, beat the egg whites on medium speed until foamy. Add the cream of tartar and increase the speed to medium-high. Beat just until stiff peaks form when the whisk is lifted. Transfer the egg whites to a separate bowl, clean the mixer bowl and reattach it with the paddle attachment.
Add the butter to the mixer bowl and beat on medium speed until smooth. Gradually add the sugar and beat until incorporated. Mix in the lemon zest. Beat the mixture on medium-high speed until light and fluffy. Add 1/4 cup of the milk and beat until just blended. Reduce the speed to low and add the flour mixture alternately with the remaining milk in three batches, beginning and ending with the flour, scraping down the sides of the bowl as necessary. Beat until just blended. Using a rubber spatula, fold one quarter of the egg whites into the batter, being careful not to deflate the mixture. Once incorporated, add in the rest of the whites and gently fold in until well combined.
Pour the batter into the prepared pans and bake until golden and a toothpick inserted in the center comes out clean, about 24-26 minutes. Cool the cake in the pan on a wire rack for 10 minutes. Run a thin knife around the outside of pan and gently turn the cake out. Allow to cool completely.
To make the raspberry curd, melt the butter in a large saucepan over medium heat. Add the raspberries, egg yolks, sugar and salt, and cook, mashing the berries. Stir frequently at first and then constantly at the end, until thickened, about 10 minutes. Pour the mixture through a coarse strainer set over a bowl, pressing hard on the solids to extract as much liquid as possible. Cool to room temperature; the curd will continue to thicken as it cools. Stir in lemon juice to taste. Cover and refrigerate until ready to serve.
Cut both cakes horizontally, so that you have 4 even cake layers. It is up to you whether you choose to make a 3 layer cake like I did (and snack on the last layer!) or make a very high, 4 layer cake. Layer the rounds with the cooled raspberry curd. Once layered, allow the assembled cakes to cool in the refrigerator to help them set. In the meantime, make the frosting. In the bowl of an electric mixer fitted with the paddle attachment, beat the butter and zest on medium speed until light and fluffy. Gradually add the sugar and beat until smooth. Add the lemon juice and beat for one minute longer.
Frost the chilled cakes with the lemon frosting. Garnish with fresh raspberries as desired.
