01 - Line an 8x8-inch baking pan with parchment paper to prevent sticking.
02 - In a large bowl, mix together rolled oats, almond butter, honey, melted butter, vanilla extract, and salt until thoroughly combined. Press the mixture evenly into the lined pan and refrigerate.
03 - Pour fruit juice into a small saucepan. Sprinkle unflavored gelatin over the juice and allow it to bloom for 5 minutes.
04 - Gently heat the juice and gelatin mixture over low heat, stirring until the gelatin is completely dissolved. Stir in honey until fully incorporated.
05 - Pour the gummy mixture into a parchment-lined small baking dish. Transfer to the refrigerator and chill for 45–60 minutes until firm.
06 - Once set, cut gummies into small cubes suitable for topping.
07 - Remove chilled oat base from the refrigerator. Evenly sprinkle diced homemade gummies, crushed freeze-dried fruit, and chopped freeze-dried candy over the surface. Gently press toppings into the oat layer.
08 - Return pan to the refrigerator and chill for an additional 10–15 minutes to secure toppings.
09 - Lift the mixture out of the pan using the parchment paper overhang and cut into 12 individual bars.
