To start, grease a springform pan with a diameter of 9 inches and place a sheet of parchment paper at the bottom. Next, heat your oven to 375˚F. For the cake, you will need 12 oz of strawberries. Take 6 oz of strawberries and cut them into small cubes. Take the remaining 6 oz and slice them in half.
In a generously sized mixing bowl, utilizing an electric hand mixer (or a stand mixer), combine 2 eggs and 1 cup of sugar and whip on high speed for 5 minutes or until the mixture becomes light in color and thick.
Incorporate 1 cup of sour cream, 1/2 cup of oil, and 1 teaspoon of vanilla into the mixture and beat at a low speed until thoroughly blended.
Combine 2 cups of flour, 2 teaspoons of baking powder, and 1/4 teaspoon of salt in a small bowl. Whisk the ingredients together until they are well incorporated. With the mixer set to medium/low speed, gradually add the flour mixture to the batter in thirds. Allow the flour to incorporate with each addition, and continue mixing until the ingredients are well combined. It is important not to over-mix the batter.
To start, pour half of the cake batter into the pan that has been prepared and ready.Next, add 6 oz of strawberries that have been diced on top of the batter, and then spread the remaining batter over the strawberries. To finish, take 6 oz of strawberries that have been halved and cover the surface of the batter with them, pressing them down slightly into the batter. Place the pan in the oven and bake at 375˚F for about 45-55 minutes, or until a toothpick inserted in the center comes out clean. Once done, allow the cake to rest in the pan for 15-20minutes before removing the ring.
Gently slide a narrow spatula along the sides of the cake to release it from the pan. Then, move it onto a cake plate. Let it cool until it reaches room temperature or becomes slightly warm. If desired, sprinkle it with some confectioner's sugar before serving. Finally, pour a generous amount of strawberry syrup on each individual slice.
