Preheat the oven to 350 degrees Fahrenheit.
In the bowl of a mixer, combine all the wet ingredients for the cake mix and mix for 1 minute.
With the mixer on low, add in the pudding mix and cake mix. Beat on medium speed for 2 minutes.
Pour the cake batter into a deep dish 9x13 pan that has been sprayed with non-stick cooking spray.
Bake for 35-40 minutes or until a toothpick inserted into the middle comes out clean.
Once the cake is done, let it cool on the counter for 20-30 minutes.
Once the cake has lightly cooled, poke holes all over it using the back of a spatula or a fork.
In a bowl, mix together the pudding mix and milk. Immediately pour the mixture over the cake, ensuring it fills the holes.
Cover the cake and place it in the refrigerator for at least 2 hours to set.
In another bowl, combine the strawberries, sugar, and vanilla extract. Gently mash the strawberries to create a chunky puree.
Top the chilled cake with whipped cream, followed by the strawberry puree.
Slice and serve chilled or room temperature. Enjoy your delicious Strawberry Cheesecake Poke Cake!
