To make the cakes

1. Prepare three 9 inch cake pans with parchment paper circles in the bottom and grease the sides. Preheat oven to 350°F (176°C).
2. Combine the flour, baking powder and salt in a medium sized bowl and set aside.
3. Add the butter, oil, sugar and vanilla extract to and large mixer bowl and beat together until light in color and fluffy, about 2 minutes. Do not skimp on the creaming time. You should visibly see a change in color and texture.
4. Add the eggs one at a time, mixing until mostly combined after each. Scrape down the sides of the bowl as needed to be sure all ingredients are well incorporated.
5. Add half of the dry ingredients to the batter and mix until mostly combined.
6. Slowly add the milk and mix until well combined.
7. Add the remaining dry ingredients and mix until well combined and smooth. Scrape down the sides of the bowl as needed to be sure all ingredients are well incorporated. Do not over mix the batter.
8. Divide the batter evenly between the cakes pans and bake for 18-20 minutes, or until a toothpick comes out with a few crumbs.
9. Remove the cakes from the oven and allow to cool for about 2-3 minutes, then remove to cooling racks to cool completely.

For the strawberries

1. Wash the strawberries, cut the stems off, and slice them.
2. Add the sliced strawberries and sugar to a large bowl and toss together. Set in the fridge for at least 1-2 hours to let the sugar bring out the juices from the berries. The longer it sits, the more juices you’ll have.

Whipped cream and assembly

1. Add the heavy whipping cream, powdered sugar and vanilla extract to a large mixer bowl and whip on high speed until medium to stiff peaks form.
2. Place the first cake layer on a cake plate or other serving platter. Add a layer of whipped cream. I used Ateco tip 808 to pipe dallops around the outer edge of the cake, then filled it in. You could also just spread a layer of whipped cream.
3. Add about half of the strawberries on top of the whipped cream.
4. Add the second layer of cake, another layer of whipped cream and another layer of strawberries.
5. Add the final layer of cake, then finish it off with some whipped cream swirls and fresh strawberries. If you have any leftover juices from the sliced strawberries, you could also drizzle that on top or serve it with the cake slices.
6. Refrigerate the cake until ready to serve. The cake layers and strawberries can be made up to a day ahead, but the cake is best if layered together the day it’ll be served.
