Vanilla Layer Cake
Ingredients
  • 4 cups sugar
  • 8 eggs
  • 5 cups all-purpose flour
  • 5 teaspoons baking powder
  • 2 cups whole milk
  • 2 cups unsalted butter (melted and cooled about 45 seconds in the microwave)
  • ½ cup oil
  • 4 teaspoons vanilla bean paste (or vanilla extract) remember the better quality vanilla the better this cake will taste.
Pastry Cream
  • 4 egg yolks
  • ½ cup sugar
  • ¼ cup cornstarch
  • ¼ teaspoon salt
  • 2 cups whole milk (divided ½ cup and 1-1/2 cups)
  • 4 tablespoons unsalted butter
  • 2 teaspoons vanilla bean paste (or vanilla extract)
Italian Buttercream Frosting
  • 2 cups sugar (separated into 1 cup each)
  • ¼ cup water
  • 5 egg whites
  • 1 pound (4 quarter sticks) room temperature butter (not soft) cut into tablespoon pieces
  • 3 teaspoons vanilla extract
Decorating Cake
  • 3 cups strawberries and blueberries
  • powdered sugar to dust over top of cake
Instructions
  1. Preheat oven to 350° (325° for dark pans)
  2. Use a baking spray to prepare 2-13X9 baking pans then place parchment on the bottom of each pan and give the parchment a light spray to ensure the cakes will release easily after being baked.
  3. In a large mixer bowl beat sugar and eggs.
  4. Mix in flour, baking powder, milk, butter, oil, and vanilla.
  5. Mix until smooth and completely blended.
  6. Pour batter evenly into each pan and bake for 35-40 minutes or until a toothpick comes out fairly clean, do not over bake. Check the cake every minute if needed to be sure you don't over bake it.
  7. Allow the cakes to cool until cool, about 30 minutes, then release them from the cake pans onto cooling racks until the cakes are completely cooled.
  8. I typically bake large cakes like this a couple days ahead of when they are needed, so I can freeze the cake to make it easier to frost and they stay moist and stay together nicely without crumbling and falling apart when sliced.
  9. I wrap my cakes at this point with plastic wrap and put them in the freezer. I put them on cardboard to keep them flat so they hold their shape.
  10. Freeze the cakes until firm (a couple hours at minimum to a few days- if you will be freezing them for more than a few days be sure to wrap them extra well so there is no frost on the cakes when you go to take them out of the freezer).
  11. Unwrap the cakes and allow them the cakes to be at room temperature for 20 minutes to be able to handle them and stack them with filling. They won't bend much, so level cakes are best. I don't prefer to trim my cakes so I place the tops of each cake to the center and add the filling to adjust for any unevenness.
  12. *I prepare the filling the day ahead so it's really cold and will fill in the middle of the cakes nicely.
  13. I like to prepare the frosting the day I'm using it.
Pastry Cream
  1. In a medium bowl mix sugar with cornstarch and salt together, then add ½ cup milk and whisk smooth.
  2. In a small bowl mix egg yolks, then add the egg yolks to the mixture and blend until creamy.
  3. In a small saucepan heat the remaining 1-1/2 cups milk to a simmer (small bubbles around the edge, not a full boil.
  4. Slowly pour the heated milk into the egg mixture while whisking constantly allowing the egg mixture to heat slowly and evenly to prevent the eggs from scrambling (if you have any lumps or egg pieces place this mixture through a fine strainer)
  5. Place the mixture into the saucepan and heat over medium-low heat until it boils about 5 minutes.
  6. Remove the pan from the heat and stir in the butter and vanilla.
  7. Place the pastry cream into a bowl and cover with plastic wrap and allow to cool, then put it in the refrigerator to get cold. (you can make this ahead of time even a couple days)
Italian Buttercream Frosting
  1. Separate egg whites into the bowl that fits a mixer, use the whip attachment.
  2. Whip the egg whites with 1 cup sugar until stiff peaks form.
  3. In a small saucepan, bring the other cup of sugar and the water to a boil and allow the temperature to come to 245° degrees.
  4. Immediately remove the pan from heat and d=rizzle the syrup mixture into the whipped egg whites mixture on medium speed.
  5. Once you've added all the syrup bring the speed up a bit to medium-high and mix until the bowl is cool to the touch. Put it on high if needed this takes about 10 minutes.
  6. Place the flat paddle attachment onto the mixture.
  7. Add in the butter a tablespoon at a time and mix on high.
  8. Drape a towel over the bowl so it won't spatter.
  9. Kepp adding the butter while the mixer is going until all the butter is added and it's creamy.
  10. If it looks curdled, keep mixing it could take 20 minutes if it's hot or there is a lot of humidity, put an ice pack on the mixer bowl if it needs chilling to become smooth. Alternatively, if you happen to refrigerate the mixture and need it warmed up to whip it, place a warm wet towel around the bowl.
  11. Add in vanilla.
  12. You can keep the frosting at room temperature for 2-3 days. If it's really hot in your kitchen or outside, you can put it in the fridge to chill it a bit if the frosting is cold allow it to come to room temperature and re-whip it before using it so it spreads nicely.
ASSEMBLING CAKE
  1. Place the first layer of cake on your serving tray, pipe some frosting around the edge, spread the pastry cream filling over the cake layer.
  2. Place the second layer of cake.
  3. Spread the frosting smoothly over the cake.
  4. Reserve a small amount of frosting to spread over the top when you will be adding the berries so they stick into the frosting.
  5. I added about 3 cups of berries onto the top of the cake and before serving it, dusted the cake with powdered sugar.
