In a saucepan, place the apple, the lemon juice and 1 tbsp honey. Bring to simmer over medium / low heat, covered with a lid. Stir every now and then to allow the apples to breakdown. Remove from the heat and set aside to cool.
Next, Place in a bowl, the yogurt, honey, 2-3 tbsp of apple compote and most of the blackbaeeries. Keep a few to decorate . Stir to combine well. Check the flavour and add extra honey if too acidic.
Pour the mixture into a popsicle holder with a stick in each and place in the freezer for 3 hours or overnight. Alternatively, place in a glass and store in freezer too cover with cling film.
Remove from the freezer a couple of minutes before serving, then dip the tray in hot water to lift the ice pop from the tray.
Enjoy immediately with a sprinkle of granola and the rest of the blackberries.
