Toss the cherries with the maple syrup and lemon juice. Divide them into four ramekins or other small serving bowls.

In a food processor, pulse together the walnuts, medjool dates, hemp seeds, chia seeds, and salt. Continue pulsing until the mixture is crumbly and broken down, but not quite sticky the way you'd want a snack bar base to be.

Divide the topping over the four bowls and serve with whipped cream, if desired. If you have extra topping left over, it will work nicely over oats, as a smoothie garnish, or served with fresh berries!
