Design a logo

I need a logo design for my business, it’s a hot chocolate shop in Vienna. I don’t want the design to include the usual cocoa beans but something I can make a brand out of as the name is quite catchy. The shop is called What The Frap - WTF. Monotone colours or black and beige. I was thinking maybe using a lightning bolt ⚡️. Something simple. The font I used in the attached doc is Nitti Typewriter - adobe.
