Strawberry Jello Cake is a moist strawberry sheet cake made with gelatin baked right into the batter and topped with fluffy strawberry cream cheese frosting.
Preheat oven to 350 degrees F. Spray a 9 x 13-inch cake pan with non-stick spray.
In a large mixing bowl, whisk together the white cake mix and strawberry gelatin.
Add the vegetable oil, eggs, milk, and vanilla extract. Mix until smooth and well combined.
Fold in the chopped strawberries until evenly distributed.
Pour the batter into the prepared pan and bake for 25-28 minutes, or until a toothpick inserted into the center comes out clean.
Remove the cake from the oven and place the pan on a wire rack. Allow the cake to cool completely before frosting.
Frosting
Add the softened cream cheese and chopped strawberries to the bowl of a stand mixer with a whisk attachment. Beat at a high speed until the strawberries are fully incorporated and broken down. The mixture should be lightly pink.
Add the powdered sugar and salt, mix until smooth.
With the mixer on medium-low speed, gradually add the heavy whipping cream and vanilla extract.
Increase the mixer to high speed and beat for about 1½ minutes*, or until stiff peaks form.
Spread the frosting evenly over the cooled cake.
Cover the cake and chill for 2 hours before serving.

Notes
Use fully softened cream cheese to prevent lumps.
Make sure the heavy whipping cream is very cold before whipping.
Fold the strawberries gently so they don’t break down too much.
