Preheat oven to 350℉. Spray mini muffin pans (you will need 2) with baking cooking spray. Set aside.
Unroll crescent rolls and place on cutting board. Separate at vertical perforations, pinching the diagonal perforations together well. You should have 4 rectangles. Sprinkle each rectangle evenly with about 1 ½ teaspoons cinnamon sugar and 1 tablespoon of the pecans, if using. Starting at long end roll up jelly roll style pinching seam well. Repeat with each rectangle. Cut into 28 total pieces.
Place 2 pieces in each mini muffin cup. Snuggle them in together. Bake at 350 degrees F. for 10 - 12 minutes, until golden. Remove pans to cooling rack. Cool completely in pan. Remove when cool.
To make glaze:
Combine glaze ingredients in a bowl until drizzling consistency. Swirl glaze covering tops of each mini cake. Do about half and then sprinkle those with purple, green and yellow decorator sugars. Repeat with remaining.
