1Heat oven to 350°F. In large bowl, mix flour, granulated sugar, egg, egg yolks, baking soda and lemon peel. Cut in butter, using pastry blender or fork, until mixture comes together and begins to form a wet dough. (Or mix with electric mixer using dough hook attachment.) Gather dough into a ball. Wrap in plastic wrap; refrigerate while making filling.
2In small bowl, mix jam, almonds and chocolate until well combined.
3With floured hands, shape teaspoonfuls of dough into about 24 balls; flatten each ball into a round. Press 1 round on bottom and up side of ungreased mini muffin cup. Spoon 1/2 teaspoon filling into cup. Top with a second round; seal edges. Repeat with remaining dough rounds and filling.
4Bake about 20 minutes or until lightly browned. Cool 2 minutes; remove from pan to cooling rack. Sprinkle with powdered sugar. Serve warm or cool.
