Bake the Cake

1. Set your oven to bake at 350 degrees F. Prepare a rimmed baking sheet by lining the bottom with parchment paper.
2. In a medium-size mixing bowl, whip egg whites to stiff peaks and set aside.
3. In a separate mixing bowl, whisk egg yolks until smooth and lightened in color. Whisk in the vegetable oil and water until smooth.
4. Measure out 1 and 1/2 cups of cake mix. Sift the cake mix into the egg yolk mixture and whisk to combine.
5. Whisk in approximately 1 cup of whipped egg whites to the cake batter mixture. Set the whisk aside. Using a spatula, gently fold in the rest of the egg white to the batter until fully incorporated and no white streaks remain.
6. Pour the cake batter into the prepared baking sheet. Smooth out evenly. Bake for 10-11 minutes (or just until the cake springs back when gently pressed with a finger) and remove.

Roll the cake

1. While the cake is still warm, generously dust the entire surface with powdered sugar.
2. Gently run a butter knife along the edges of the cake to loosen it from the sides. Lay a clean kitchen towel over the top of the cake. Place another baking sheet or large cutting board over the top and invert, removing the parchment paper from the cake.
3. Generously dust the cake again with powdered sugar. Tightly roll up the cake from the short side to the short side with the towel. Set the towel-wrapped cake aside on a cooling rack to cool completely, for about 2 hours.

Fill the cake (Here I am using Stabilized Whipped Cream)

1. Beat the cream cheese until smooth. Slowly add the cream and sugar to the cream cheese and continue to beat until fully incorporated. (You may need to scrape the bowl with a spatula.) Beat in the vanilla, then beat the mixture on high until whipped and light, about 3-5 minutes.

2. Spread evenly onto the unrolled cake, all the way to the edges. (Optional: set aside some whipped cream to pipe decorations on the cake later.) Sprinkle chopped strawberries evenly over the filling. Tightly roll the cake back up and set it on a serving dish. Dust the top with powdered sugar. Slice and serve.
