Almond Cinnamon Buns

Preheat oven to 375 degrees F. Meanwhile, in a medium bowl, stir almonds, almond paste, brown sugar, and cinnamon to combine. Set aside. Working on a sheet of parchment, unroll 1 package of crescent-roll dough to a rectangle and smooth seams. Evenly spread half the butter over dough and then sprinkle with half the almond mixture. Beginning on one long side, tightly roll up dough. Slice into 6 pieces. Repeat with remaining dough, butter, and almond mixture. Spray two 6-cavity muffin tins with cooking spray. Place a bun in each cavity and bake until golden brown, about 15 minutes. Remove pans from oven and let cool for 20 minutes. Meanwhile, in a small bowl, whisk confectioners' sugar and milk until smooth. Transfer buns to a wire rack, drizzle with icing, and serve immediately.
