In a bowl, mix the almond flour, maple syrup, melted coconut oil, cinnamon, and sea salt until crumbly and moist.
Line a 12-cup muffin tin with paper liners and press about 1 tablespoon of crust mixture into each cup.
Refrigerate while preparing the filling.
Beat the cream cheese with a hand mixer until smooth.
Add the Greek yogurt, honey, vanilla extract, almond extract (if using), pistachio butter, and lemon juice, then beat again until light and fluffy.
Fold in the finely ground pistachios.
Spoon the filling evenly over the chilled crusts and smooth the tops.
Refrigerate for at least 4 hours or overnight until fully set.
Remove from the muffin tin, peel off liners, and garnish with extra chopped pistachios, fresh raspberries, or a dollop of Greek yogurt if desired.
