Bring the grapes and clean and wash them well under the tap running water.
Then bring some of the toothpicks and put them in the grapes one by one.
Bring a cooking pot and pour some water into this pot. Add sugar to the water-filled pot and then start boiling on medium heat.
While simmering both the sugar and water also pour the corn syrup into it.
Continue boiling for 5-8 minutes. After enough boiling turn off the heat. Bring the vanilla extract and pour it into the cooked sugar syrup.
Bring the cleaned and washed grapes and then dip each grape in the cooked syrup.
The whole grape should be well coated with the syrup. Now bring the crushed candies and coat the candy layer over the syrup-coated grapes.
Line a baking dish with parchment paper and put the coated grapes on this parchment paper one by one.
Your Crack grapes are ready to serve after a chilling of half an hour.
