Ingredients
  

For the Cake

  • 3 Cups All Purpose Flour
  • 1 Tablespoon Baking Powder
  • 1 Teaspoon Kosher Salt
  • 1 Cup 2 sticks Unsalted Butter room temperature
  • 1 ¾ Cup Granulated Sugar
  • ⅓ Cup Vegetable Oil
  • 3 Whole Eggs
  • 2 Egg Whites
  • 1 Tablespoon Vanilla Extract
  • 1 Cup Buttermilk
  • ¼ Cup Greek Yogurt

For the Frosting

  • 3 Cups Powdered Sugar
  • 1 Cup Unsalted Butter Room Temperature
  • ¼ Cup Heavy Cream
  • 1 Small Pinch Salt or two
  • ¼ Cup Freeze Dried Strawberries - crushed or blended

Instructions
 

For the Cake

  • Preheat to 325°F (160°C) and generously grease a 9x13 pan.
  • Cream butter, oil, and sugar for 3 minutes.
  • Add eggs one at a time, mixing well.
  • Stir in vanilla.
  • Whisk dry ingredients separately, then alternate adding them with buttermilk.
  • Mix in Greek yogurt, then beat 45 seconds.
  • Pour into the pan and bake for 28-30 minutes, until a tester comes out clean.
  • Cool in the pan for 10–15 minutes, then turn out onto a rack to cool completely.

For the Frosting

  • Place the butter in the bowl of a stand mixer fitted with the paddle attachment. Mix on medium speed until paste-like, then increase to medium-high and mix for 4–6 minutes until the color changes from yellow to white.
  • While mixing, sift the powdered sugar using a fine-mesh sieve or sifter into a separate bowl.
  • Crush or blend Freeze-dried Strawberries
  • Turn off the mixer and add the powdered sugar in 1–2 cup increments, mixing on low speed after each addition until fully incorporated. This prevents a sugar cloud.
  • Add the heavy cream, salt, and vanilla extract and freeze-dried strawberries. Mix on medium speed for 30 seconds to incorporate.
  • Increase to medium-high speed and mix for 5–10 minutes, pausing occasionally to scrape down the bowl.
  • Remove any air bubbles by pressing and smoothing the frosting with a spatula or wooden spoon in a zig-zag motion prior to frosting your cake.
