Combine the apple cider, maple syrup, cinnamon, and sliced apple in a saucepan and bring to a gentle boil over medium heat.

Continue stirring periodically for 10 minutes.

After it has reduced and thickened, remove from heat and smash the apples.

Allow the syrup to cool completely, then strain through a mesh strainer and store in an airtight container.

Combine the chai concentrate and oat milk in a large glass and sweeten to taste.

Stir well and pour over ice in the glass.

In a small glass, stir to combine the oat milk and the apple crisp syrup.

Use a frother to froth the oat milk until thickened, foamy, and bubbly.

Pour the frothy mixture over the latte, top with a sprinkle of cinnamon and enjoy!
