Strawberry-Rhubarb Dream Cake Recipe

  1. For the cake, preheat the oven to 350. Spray three 8-inch round cake pans with baking spray and line with parchment paper.
  2. In the bowl of a stand mixer fitted with the paddle attachment, cream together the butter and sugar until light and fluffy, about 3-5 minutes on medium-high. Add the eggs, one at a time, incorporating thoroughly and scraping down the bowl after each addition. Stir in the vanilla bean paste.
  3. In a separate bowl, whisk together the flour, baking powder and salt. With the mixer on low, add a third of the flour mixture to the butter-sugar mixture. Add in half of the buttermilk. Repeat with the second third of the flour and the remaining buttermilk. Add in the remaining flour and still until just incorporated. Fold in the rhubarb.
  4. Divide the batter among the three pans and bake for 30 minutes, or until the top of the cake is golden and a toothpick inserted comes back clean. Set aside to cool.
  5. For the filling, stir together the halved strawberries, lemon zest, and sugar in a large bowl. Let sit for 10 minutes.
  6. In the bowl of a stand mixer fitted with the whisk attachment, whisk together the heavy cream, mascarpone, confectioners’ sugar, and vanilla bean paste until they form stiff peaks.
  7. Place one cake layer on a serving platter. Brush an even layer of the strawberry juice from the bottom of the bowl of strawberries onto the first layer. Place an even layer of strawberry halves, cut side down, onto the cake. spread half the cream on top of the strawberries. Freeze for 15 minutes to set.
  8. Put the second layer of cake on top of the first and press gently to stick. Brush evenly with the strawberry juice and the layer of strawberries. Spread the remaining filling over the top. Freeze for 15 minutes to set.
  9. Place the last layer of cake over the filling and press gently to set. Using a large offset spatula, remove any filling that has oozed from the layers. Line the outside of the cake with parchment to stabilize it, using two pieces and taping them together to make a tight fit. Freeze overnight or for 3-4 hours.
  10. For the buttercream, put the egg whites and vanilla bean paste in the bowl of a stand mixer fitted with the whisk attachment.
  11. In a large saucepan, combine the granulated sugar with 1 cup of water. Stir constantly over medium heat until the sugar has melted. Attach a candy thermometer to the side of the pan. As the temperature of the syrup reaches 225F, start whisking the egg whites so that they start to get foamy. Continue heating the syrup until it reaches 240F.
  12. Slowly pour the syrup down the side of the stand mixer bowl, into the egg whites with the mixer on medium-low. Increase the speed to high and whip until the egg whites form stiff peaks and the bowl is cool to the touch.
  13. With the mixer on medium, add the butter one tbsp at a time. Whisk until mixer is smooth and creamy.
  14. Coat the cake with the buttercream and, if frozen, allow to defrost in the fridge for 2 hours. Garnish with reserved whole strawberries and pistachios.
