Line a 9x13 sheet cake pan with parchment paper and set aside.
Preheat the oven to 350 Fahrenheit.
In a large mixing bowl, combine the butter, oil and sugar. Beat with an electric mixer for about 30 seconds.
Add in the remaining wet ingredients and beat until combined.
Add in the flour, baking powder, baking soda and salt. Be sure to spoon and level the flour, don't scoop from the bag.
Beat just until combined.
Add to the prepared cake pan and bake for 35-45 minutes or until a toothpick comes out clean.
Let cool completely, you can just leave it right in the pan and frost it from there, or transfer to a board or wire rack for serving.
Top with your frosting of choice, berries, sprinkles or whatever you like and enjoy!
