Preheat your oven to 350°F (175°C). Line two round cake pans with parchment paper and lightly grease the sides.
In a large bowl, or the bowl of your stand mixer, combine the cake mix and strawberry Jello.
Add 2/3 cup of avocado oil and the eggs and beat on low to medium speed until smooth.
Gently fold in the thawed strawberries until evenly distributed.
Pour the batter into the prepared cake pans and bake for approximately 1 hour, or until a toothpick inserted into the center comes out clean.
Allow the cakes to cool in the pans for 10 minutes, then transfer to a wire rack to cool completely.
