This is a recipe for "Choco Maro," which can be easily made with just three ingredients: chocolate bars, marshmallows, and milk (jam is optional), and a silicone mold from a 100-yen store. Melt the chocolate bar in the microwave, pour it into the silicone mold, coat the sides with chocolate, and chill in the refrigerator until hardened. Next, heat the marshmallows and milk in the microwave, melt and mix, and add strawberry jam or orange marmalade to change the flavor as desired. Place the marshmallows into the chilled chocolate mold, cover with the remaining chocolate, and chill in the refrigerator again until hardened. It's easy enough for beginners to make, and these cute cube-shaped chocolate sweets are perfect for events like Valentine's Day or as a small gift.
