In small saucepan, place coffee and maple syrup. Bring to a boil, reduce heat to medium-high to maintain a strong boil, and heat, uncovered, until reduced to 1/3 cup, about 15 minutes. Stir in cacao powder, vanilla, and cinnamon until smooth. Let cool. The sauce will thicken further.
To serve, divide yogurt among 4 serving bowls and drizzle on espresso sauce. Top with granola, raspberries, and cacao nibs, if using.
