The present invention relates to a method for preparing energy bars by using Ecklonia cava to let users easily carry and consume the energy bars as needed in any place and at any time. The method for preparing energy bars by using Ecklonia cava includes: (a) mixing 9-32 wt% of roasted brown rice, 8-12 wt% of cranberries, 8-12 wt% of peacans, 8-12 wt% of macadamia, 6-9 wt% of roasted sunflower seeds, 11-14 wt% of roasted almonds, 9-11 wt% of walnut, and 18-21 wt% of hemp seeds to prepare a nut mixture； (b) forming solids by heating and boiling 60-80 wt% of the nut mixture in step (a) and 20-40 wt% of saccharides in a cooking container at 100°C or higher and hardening the boiled product in a frame； (c) roasting Ecklonia cava powder prepared by grinding dried Ecklonia cava for 4-6 minutes at 60°C-80°C； (d) uniformly spraying the Ecklonia cava powder roasted in step (c) on the upper part of the solids hardened in the frame in step (b)； (e) preliminarily aging the frame in step (d) in a refrigerator maintaining a constant temperature of 0°C-1°C for five to seven hours； (f) uniformly coating a cacao paste ingredient onto the upper part of the solids sprayed with the Ecklonia cava powder after taking out the frame from the refrigerator in step (e)； (g) secondarily aging the frame in step (f) in the refrigerator maintaining a constant temperature of 0°C-1°C for 3-6 hours； and (h) taking out the solids from the frame in step (g) and cutting the solids in the desired shape and size.본 발명은 언제어디서든 공복이나 에너지를 필요로 하는 경우 쉽게 휴대하고 있다가 간편하게 꺼내어 섭취할 수 있는 감태를 이용한 에너지바의 제조방법에 관한 것으로, 그 구성은, a) 볶은현미 9 - 32중량%, 크랜베리 8 - 12중량%, 피칸 8 - 12중량%, 마카다미아 8 - 12중량%, 볶은해바라기씨 6 - 9중량%, 볶은아몬드 11 - 14중량%, 호두 9 - 11중량%, 햄프씨드 18 - 21중량%를 혼합하여 견과혼합물을 준비하는 단계； b) 상기 a)단계의 견과혼합물 60 - 80중량%와 당류 20 - 40중량%를 조리용기에 넣고 100℃ 이상의 온도로 가열하여 조린 후 조려진 그들을 형틀에 넣고 양생하여 고형물을 형성하는 단계； c) 건조된 감태를 분쇄한 감태분말을 60 - 80℃의 온도로 4 - 6분간 덖음하는 단계； d) 상기 b)단계의 형틀 내부에서 양생된 고형물 상부에 상기 c)단계의 덖음된 감태분말을 골고루 뿌려주는 단계； e) 상기 d)단계의 형틀을 0 - 1℃의
