Blessing on a Biscuit Dipped in Tea

I enjoy eating a biscuit when I dip it in tea (of course, I wash my hands without a blessing because it is food dipped in a liquid). The question is, can one bless on a biscuit dipped in tea, 'Borei Minei Mezonot', and then bless on the tea 'Shehakol'?

It is not correct to do so. The proper way is to bless 'Borei Minei Mezonot' on the biscuit without the tea, and then 'Shehakol' on the tea (when intending to drink it even without the biscuit), and then dip as desired.

Mishna Berura, Siman 168, S"K 65: "And according to this, regarding the drinking of coffee as practiced among us, where pastry is dipped in it, and there his intention is also for both, it seems correct that before blessing on the pastry, one should bless on the coffee 'Shehakol' and drink a little, and it is better to first bless on the pastry alone without soaking, and then bless first on a little sugar with the blessing 'Shehakol' to include the coffee." Regarding blessing on the sugar and not the coffee itself, the poskim write that this is only when there is no desire to drink the coffee by itself. But if one wants to drink it by itself, one can bless on the coffee 'Shehakol'.
