Fill a medium bowl with water and add 1 tablespoon of lemon juice. Slice your apple into thin, even wedges (about 5-7 slices depending on the size of the apple). Soak the apple slices in the lemon water for a couple of minutes to prevent browning. Pat the slices dry with a paper towel and place on a parchment paper lined cookie sheet or large plate.
In a small bowl, mix together 1/4 cup cashew butter, 2 tablespoons maple syrup, 1/2 teaspoon vanilla extract, and a pinch of salt until smooth. If the mixture is too thick, add a teaspoon of water to thin it out slightly.
In a microwave-safe bowl, combine 1/4 cup chocolate chips and 1/2 teaspoon coconut oil. Microwave in 30-second intervals, stirring after each interval, until the chocolate is fully melted and smooth.
Spread a spoonful of the cashew butter mixture onto each apple slice, covering the top evenly. Sprinkle the toasted coconut on top of the cashew butter layer.Drizzle the melted chocolate over the coconut-topped apple slices using a spoon, piping bag, or snack bag. Allow the chocolate to set for a few minutes at room temperature or in the fridge before serving. Enjoy your Samoa caramel apple slices right away or store them for later!
