Slice your oranges in half and use a juicer to extract all that delicious juice. You’ll need about ½ cup for this recipe.
Gently scoop out any leftover pulp and line the orange halves in a muffin tin to keep them stable.
In a medium mixing bowl, pour in the fresh orange juice and sprinkle the unflavored gelatin over the top. Give it a gentle stir and let it sit for 2 minutes to bloom.
Pour in the boiling water and stir in the orange Jello until fully dissolved.
Stir in the Aperol and bubbly Prosecco.
Carefully pour the mixture into the prepared orange halves. Fill them up, but leave a tiny bit of space at the top.
Place the tray in the refrigerator and chill for at least 2-4 hours or overnight until set.
Once set, slice each orange half into quarters using a sharp knife. You’ll end up with Aperol jello wedges that look like the cutest little citrus slices!
