Preheat oven to 375°F. Lightly grease or line a mini muffin tin.
Slice 12 cherries into quarters (these will be placed on top of each muffin), and chop remaining cherries. Set aside.
In a large bowl, whisk to combine flour, baking powder, and baking soda.
In a small bowl, whisk eggs, yogurt, sugar, oil, and orange juice/zest until thoroughly combined. Pour into dry mixture and stir just until blended. Gently fold in the chopped cherries and the chia seeds.
Fill each muffin with 1 tablespoon of batter and top with one of the cherry quarters. Bake until a toothpick inserted in the center comes out clean, about 12 minutes. Refrigerate or freeze leftover muffins in an airtight container.
