Begin by gathering all your ingredients: white chocolate chips, mini marshmallows, fruit jelly candies, and butter. Set a heatproof bowl or double boiler over simmering water on medium heat.

In the heatproof bowl, combine the white chocolate chips and butter. Stir gently as they melt, keeping a close eye to prevent overheating, which can ruin the texture. It should take about 5-7 minutes for the mixture to become smooth and glossy.

Next, fold in the mini marshmallows into the melted chocolate and butter mix. Continue stirring gently until the marshmallows start to soften but are not completely melted, approximately 1-2 minutes.

Now it's time to mix in the fruit jelly candies. Stir them evenly into the nougat mixture, ensuring that every bite of your Jelly Nougat Candy will be bursting with colorful flavor.

Pour your nougat and jelly mixture into a lined baking dish, spreading it out evenly with a spatula. Press down lightly to compact it for a nice shape. Let it rest on the counter for a few minutes before chilling.

Refrigerate the assembled Jelly Nougat Candy for at least 2 hours or until fully firm. This chilling time is crucial for developing the right texture.

Once set, remove the Jelly Nougat Candy from the fridge. Using a sharp knife dusted with powdered sugar, carefully cut it into squares.
