5. Add the blue pea powder  into egg yolk mixture and mix well.
6. Next, add 1/3 of first portion of meringue into blue yolk mixture and mix to lighten the batter.
7. Pour the yolk mixture into the rest of meringue and fold gently until well combined.
8. Pour the batter into 30*40cm prepared tin and tap the air bubble.
9. Bake at 170C for 15-20 minutes or until golden brown.
10. Remove from oven and immediately loosen cake from sides of pan and trim the sides and cut into half. Carefully remove paper. Cool completely.
11. Repeat step 1-10 for 2nd cake by reduced the blue pea flower powder to 3-4g.
12. Filling: In high speed, beat buttercream and mascarpone for few minutes until smooth and combined. Add the crushed oreo and fold until combined.
