Size of Bracha Achrona

If I eat a Twix bar- it has a cookie inside chocolate. The cookie is under kezayit and the chocolate is also under kezayit, but together it’s more than kezayit. Do I make boreh nefashot after?

No
For those who are wondering.
Although the m.b. siman ר”י wrote like the m.a. to say bore mefashot but Maran chacham Ovadia proved that you don’t say any Bracha at all.

RABBI SHAY TAHAN
