If you love strawberries you will love this cake! I used a cake mix (just because I had one), doctored up equate to the original recipe. I will list both versions below.
This frosting is absolutely a show stopper! My grandson said it was the best cake he has ever eaten. You for sure want to make this one for that next special occasion. Perfect for Valentine"s Day. THIS CAKE MUST BE KEPT REFRIGERATED.
ORIGIONAL RECIPE:
1 pound fresh strawberries, washed and hulled
¾ cup salted butter, softened
¼ cup vegetable oil
1½ cups sugar
¼ cup sour cream
1½ tsp vanilla extract
1 tsp strawberry extract
3½ cups cake flour
4 tsp baking powder
½ tsp table salt
3 large eggs, room temp
1 cup buttermilk, room temp
pink food coloring, optional
Add strawberries to a blender or food processor and puree until smooth. Pour into a small saucepan and bring to a simmer. Let simmer, stirring occasionally, util the mixture is thick and reduces by half, about 20 minutes. You should end up with just over 1 cup of reduced puree. Set aside for later use in both the cake and the frosting.
Lightly grease two 9" cake pans. Line the bottoms with parchment paper. Preheat oven to 350 degrees.
In a large mixing bowl, use a hand mixer to cream the butter, vegetable oil, and sugar together until creamy, about 2 minutes. Beat in one cup strawberry puree, sour cream, vanilla, and strawberry extract, if using. Reserve the remaining strawberry puree, up to ¼ cup, for the frosting.
Use a fork to combine the eggs and buttermilk together. Set aside.
In another bowl stir together cake flour, baking powder, and salt.
Add ⅓ of the dry ingredients to the butter mixture, and mix until just combined. Add half the milk mixture and combine. Add in another ⅓ of the dry ingredients until combined followed by the remaining milk mixture. Add remaining dry ,mixture and mix with hand mixer until just combined. Stir in food coloring, if using, adding a little at a time until desired color is achieved.
Divide the batter evenly between the pans. Bake at 350 for 25-30 minutes. Let sit in pans for 5 minutes and then transfer to a wire rack to cool completely before frosting.
MY CAKE MIX VERSION:
1 pound fresh strawberries, prepared and reserved as in original recipe above
I box of strawberry cake mix
1 cup melted butter, cooled
¼ cup sour cream
1 tsp vanilla
4 large eggs
1 cup buttermilk
Combine cake mx, cooled melted butter, sour cream. eggs, and vanilla. Add buttermilk. Fold in 1 cup of strawberry puree. Mix and bake as directed on box.
NOTE: I live in a high altitude area so I have to add ¼ cup flour, and reduce the baking temperature to 325 degrees, and bake a little longer.
STRAWBERRY CHANTILLY CREAM FROSTING
2 cups heavy cream
1 tsp vanilla
1.5 oz instant strawberry jello
2 cups powdered sugar, divided
8 oz cream cheese, softened
8 oz mascarpone cheese, softened
reserved strawberry puree
In a large bowl, use a hand mixer to whip cream and vanilla extract. Slowly add in strawberry jello while mixing. Once the cream reaches soft peaks, slowly add in ½ cup of the powdered sugar. Continue beating until stiff peaks form.
In a separate bowl, beat together cream cheese, mascarpone, and remaining ¼ cup strawberry puree. Whip until smooth, about 2 minutes. Add in the remaining 1½ cups powdered sugar. Mix until well combined.
Use a rubber spatula to fold the whipped cream mixture into the cheese mixture. Combine until no streaks remain. Frost the cake as usual. Refrigerate cake.
