In a medium saucepan, whisk together Jello mix, pudding mix, and water. Cook over medium heat and bring to a boil.
Remove the saucepan from heat and pour into a large mixing bowl. Cover with plastic wrap.
Refrigerate until mixture has thickened (overnight or for about 4-6 hours).
Once mixture has thickened, beat until creamy with an electric hand mixer.
Fold in Cool Whip, marshmallows, and fruit. Chill for about an hour before serving.
Notes
We would not recommend making this further in advance than the morning you’re planning on eating it. The peaches tend to release moisture the longer they are in the salad, so it starts getting runny after too long.
We recommend only using Cook and Serve pudding with this recipe. It doesn’t set up as well, stay together as long, or have quite as creamy of a texture if you use instant pudding.
Sometimes I also add a can of drained pineapple tidbits or sliced bananas to this recipe – it’s a delicious addition!
I have been able to find peach jello at Walmart and Target; you can also find it on Amazon!
