Method
 

Step 1: Prepare the Cake Pans

  2. Grease three 8-inch pans, line bottoms with parchment, and lightly flour the sides.
Step 2: Mix the Dry Ingredients
  1. In a large bowl, whisk together:
  2. Flour
  3. Baking powder
  4. Salt
  5. Cinnamon
  6. Set aside.
Step 3: Beat the Sugars & Fats
  1. In a stand mixer, cream together:
  2. Butter
  3. Brown sugar
  4. Granulated sugar
  5. Beat until fluffy (3–4 minutes). Scrape the bowl.
  6. Add:
  7. Oil
  8. Vanilla
Step 4: Add Egg Whites
  1. Gradually add egg whites while mixing on low-medium speed.
  2. Beat until mixture is silky and light.
🥚 Why egg whites? They give the cake a delicate, airy texture and light color.
    Step 5: Alternate Wet & Dry Ingredients
    1. With mixer on low, alternately add:
    2. Dry ingredients
    3. Buttermilk
    4. Begin and end with dry mix. Do not overmix.
    Step 6: Bake the Cakes
    1. Divide batter evenly between pans.
    2. Bake for 28–32 minutes or until toothpick comes out clean.

    7. Vanilla
    8. Salt
    9. Slowly pour in double cream and beat for another 2–3 minutes until whipped and creamy.

      ❓ 10 FAQs
      1. What is Biscoff?
      Biscoff cookies are caramelized spiced biscuits originally from Belgium — and cookie butter is the spreadable version.
      2. Can I use crunchy cookie butter?
      Yes, for a more textured frosting! Creamy is best for a smooth finish.
      3. Is this cake very sweet?
      It’s rich and sweet, but the spices and frosting balance it beautifully.
      4. Can I use whole eggs instead of whites?
      Yes — 3 whole eggs, but the cake will be slightly denser and more golden.
      5. Can I use milk instead of buttermilk?
      You can, but buttermilk provides tenderness and tang. For a sub: mix milk with a splash of lemon juice.
      6. How do I keep the cake moist?
      Don’t overbake and store well-wrapped. Buttermilk and oil ensure moisture.
      7. Can I make this ahead?
      Yes! Bake layers 1–2 days ahead, store chilled and frost the day of.
      8. What if I don’t have double cream?
      Use heavy cream or whipping cream with at least 36% fat.
      9. Can I make it gluten-free?
      Yes — use a 1:1 gluten-free baking mix, but Biscoff cookies are not gluten-free.
      10. Can I toast the cookies?
      Yes — toasting crushed Biscoff brings out caramel notes and adds crunch.
