Sounds unusual. You can either say :"אני אוהב סוכריות" (I love candy(ies)-in general) or "אני אוהב את הסוכריה" (I love the candy-talking about a specific candy).
Hope it helped :)
What's the actual difference between "ממתקים" and "סוכריות"? They both seem to translate as candies (American English).
Not very common, but might be used to mean "I like eating/receiving a candy"
