Prepare a muffin tin with paper liners. Preheat oven to 350° F.
Make the crust: In a bowl, mix graham cracker crumbs with melted butter, stirring until evenly hydrated.
Add about one tablespoon of mix to each muffin cup, firmly pressing into each liner. Bake for 5 minutes.
Make the cheesecake: Beat cream cheese in the bowl of a stand mixer with the paddle attachment or with electric beaters until soft and creamy, 1-2 minutes.
Add sugar; cream until light and fluffy, one additional minute.
Add yogurt, vanilla, lemon juice, and lemon zest, mixing until incorporated. Scrape down the sides and bottom of the mixing bowl and give it a quick mix. Beat in eggs, one at a time, mixing gently just until combined.
Remove from mixer and fold huckleberries in lightly by hand. Pour or scoop batter into muffin cups, filling them all the way to the top.
Bake until cooked through and just a tiny bit of jiggle is left, 17-21 minutes.
Cool: Allow cheesecakes to cool 10-15 minutes before removing from pan. Then, cool them at room temperature for about another 30 minutes. Finally, chill in the refrigerator for at least 2 hours before serving.
While baking, make huckleberry compote (optional): Add berries, sugar, and lemon juice to a heavy-bottomed sauce pan. Cook until berries break down and mixture thickens, about 5-7 minutes. Cool completely.
Serve: Once cheesecakes are fully cool, top with optional huckleberry compote and whipped cream**, or serve as-is. Best eaten cold.
