Equipment

  • Hand-held Mixer
  • Whisk
  • Wooden Spoon
  • 8" x 4" x 2½ Loaf Pan

Ingredients

  • 1 Stick Unsalted Butter, plus 2 Tbsp.
  • 3 Large Eggs; 1 egg separated (yolk from white)
  • ½ Cup Sugar
  • 1 tsp. Vanilla Extract
  • 1 Cup All-Purpose Flour, plus 2 Tbsp.
  • ½ tsp. Baking Powder
  • ¼ tsp. Kosher Salt
  • 1 Cup Fresh Blueberries

Instructions

  • Preheat the oven: Begin by preheating your oven to 350 degrees F. Spray an 8" x 4" x 2½" (or equivalent) pan with baking spray. Set aside.
    Prepare the ingredients: Take 1 egg and separate and separate the yolk from the white. Reserve the egg white in a small bowl. Add the other 2 eggs (whole – egg yolks and whites) and the egg yolk from the 1 separated egg in another bowl. 
    Mix the Ingredients: In a bowl, cream the butter. Then add the sugar and eggs. Mix again to combine to a creamy texture.

  • Whisk The Egg White: In a medium bowl with a hand-held mixer, whisk the egg white until it forms a stiff peak. Set aside. 
    Add In the Remaining Ingredients: To the creamy butter mixture, add in the vanilla extract, all-purpose flour, baking powder, and salt. Mix well to combine. 
    Gently fold in the egg white until combined, then gently fold in 1 cup fresh blueberries. 
    Bake The Blueberry Loaf Cake: Pour the batter into the prepared pan. Bake the cake for about 60 minutes or until a toothpick inserted near the center comes out clean.

Notes

Recipe Notes: 
  • Be sure to set your timer. We recommend that you check your cake before the baking time ends. Everyone’s baking style and appliances are different. I recommend at least 10 minutes before the time ends, you check your cake by inserting a toothpick in the center to see if it comes out clean. You do not want the cake to overbake.
  • Avoid cold butter.  I can’t stress enough how important it is for you to use room-temperature butter. It’s easy to cream room-temperature butter and it’s the start of a successful cake recipe.
  • Add the ingredients one at a time. Do not be in a rush to add all the ingredients together as you will risk the possibility of having a super-dense cake.  Each ingredient must be added one at a time for proper mixing. 
  • Do not overmix the flour. When you overmix the All-purpose flour, it gives it a chance to create gluten faster and this will change the density/fluffiness of the cake. If you are using a hand-held mixer, we recommend that you mix the flour at a low speed. However, it’s best to use a wooden spoon to mix the flour, and a silicone baking spatula to fold in the ingredients such as the egg white and blueberries.
