Ingredients

• cooking spray
• 1 (3 ounce) package berry blue gelatin
• ½ cup white sugar
• 3 ¾ cups boiling water, divided
• 1 (3 ounce) package strawberry gelatin
• 1 (.25 ounce) envelope unflavored gelatin
• ¼ cup cold water
• ½ (14 ounce) can sweetened condensed milk

Directions

Step 1

Line two 4×8-inch loaf pans with foil; coat with cooking spray. Stir together berry blue gelatin and 1/4 cup sugar in a bowl with 1 1/2 cups boiling water until dissolved. Pour into the first prepared pan. Stir together strawberry gelatin and remaining 1/4 cup sugar in a bowl with 1 1/2 cups boiling water until dissolved. Pour into second prepared pan. Chill both mixtures until set, at least 3 hours.

Sprinkle unflavored gelatin over 1/4 cup cold water in a bowl. Let stand 5 minutes. Add remaining 3/4 cup boiling water and whisk until dissolved. Stir in sweetened condensed milk and let cool to room temperature.

Meanwhile, line a 9×13-inch pan with foil, leaving a 2-inch overhang on long sides, and coat with cooking spray. Turn chilled gelatins out onto a cutting board and coarsely chop. Transfer to prepared pan, then pour in milk mixture. Chill until set, at least 3 hours.

Use foil to carefully lift gelatin mixture and transfer to a baking sheet, then fold down edges of foil. Insert 8 wooden sticks, spaced evenly, on each long side of the gelatin block. Freeze overnight.

Let frozen gelatin stand at room temperature 15 minutes. Cut into 16 ice pop-sized rectangles.
