I was looking for an amazing, fruity cake for a BBQ. I wanted to use rhubarb because it's in season and of course strawberries because they pair perfectly. I had an idea of what I wanted so I found two recipes and mashed them together and made them my own! Baking a cake like this can be a lot of work. Especially if you have a toddler ha! I baked the cakes two days in advance and froze them. Then I made the mousse and buttercream day of, placed it in the fridge and took it out 2 hours before serving it so it could come up to room temp. This cake is super yummy and I received a lot of compliments!
1 cup unsalted butter
2 cups granulated sugar
5 eggs, at room temperature
1/4 tbsp vanilla bean
2 cups granulated sugar
5 eggs, at room temperature
1/4 tbsp vanilla bean
1 tsp vanilla extract
3 cups flour
1 tbsp baking powder
1 tsp salt
1 1/4 cups buttermilk
2 cups diced rhubarb
3 cups flour
1 tbsp baking powder
1 tsp salt
1 1/4 cups buttermilk
2 cups diced rhubarb
1 envelope unflavored gelatin
1/4 cup water
2 cups fresh strawberries, diced
1/4 cup granulated sugar
1/4 cup water
2 cups fresh strawberries, diced

Vanilla Bean Buttercream: Adapted from Eats Well With Others
6 egg whites
1/4 tsp vanilla beans
1/4 tsp vanilla beans
1 tsp vanilla extract
1 cup sugar
1 lb unsalted butter, cut into small pieces, slightly cooler than room temperature
1 cup sugar
1 lb unsalted butter, cut into small pieces, slightly cooler than room temperature
CAKE:
preheat the oven to 350. Spray three 8-inch round cake pans with baking spray and line with parchment paper.
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.
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.
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.

MOUSSE:
Sprinkle gelatin over water in a medium bowl; let stand for five minutes. Place strawberry and sugar into a small saucepan and bring to a boil over medium-high heat. Remove from the heat. Add the gelatin mixture to the strawberry mixture, whisking constantly until gelatin has dissolved. Chill until cool, stirring occasionally, about 30-45 minutes.
Using a whisk or hand-held mixer, beat the cream until soft peaks form. Fold whipped cream into strawberry mixture until no streaks remain. Cover and chill for 30 minutes or until mixture is thick enough to hold its shape when mounded between cake layers. Spread about 1 cup of the strawberry mousse filling between each cake layer, leaving a 1/4-inch border around all edges; cover and chill for 3 hours or until mousse is set.

BUTTERCREAM:
Put the egg whites and vanilla bean and extract in the bowl of a stand mixer fitted with the whisk attachment.
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. It may take a while but it will get there.
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.
With the mixer on medium, add the butter one tbsp at a time. Whisk until mixer is smooth and creamy. It will look like its breaking but its just emulsifying so don't worry, just keep mixing until it starts looking creamy.
Coat the cake with the buttercream and top with fresh strawberries. Serve cake at room temp.
