Too bad, you don't like this aromatic and exotic caffeine drink.

But no pressure pal, yeah, you can omit espresso powder if you desire. Usually in all baking and cooking recipes with coffee powder as an ingredient, the purpose is that it actually enhances the flavor of chocolate. It usually is not prominent, but if you don’t want to use it, you can omit it. Substituting for freshly brewed coffee depends on the amount called for. If it’s a tablespoon or two, you can omit or substitute vanilla extract. If it’s any more than that, I would recommend substituting hot water so that the final texture isn’t affected. Also, you can just do away with cinnamon or nutmeg powder to maintain the aromatic taste.
