Prep the fruit: If your berries are large (like strawberries), hull and halve them.
If you’re using frozen fruit, there’s no need to thaw.
Load the blender: Add bananas, berries, yogurt, milk, sweetener, vanilla, and a pinch of salt. Include any optional add-ins you like.
Blend until smooth: Start on low, then increase speed until the mixture is silky. If it’s too thick to blend, add a splash more milk.
Taste and adjust sweetness.
Pour into molds: Transfer the mixture to popsicle molds, leaving a little headspace for expansion.
Add sticks: Insert popsicle sticks. If your mold requires partially freezing before adding sticks, follow those instructions.
Freeze solid: Freeze for 4–6 hours, or until fully set. Overnight is even better.
Unmold: Run warm water over the outside of the molds for 10–15 seconds, then gently wiggle the pops free.
Serve: Enjoy right away, or store for later (see storage tips below).
