Preheat the oven to 175ºC.
In a mixer bowl, cream the butter and sugar on high speed with a hand mixer or stand mixer until light and fluffy (about 2-3 minutes).
Beat in one egg at a time, scraping the sides and bottom of the bowl between additions. Pour in the maple syrup, and mix well.
Sift in cake flour, baking powder, and salt. Fold the batter until just combined. Do not overmix.
Transfer the batter to a piping bag, then fill each fall-themed cake cavity about half full. Use a spoon to evenly spread out the batter in each cavity. I made two batches - 14 mini cakes.
Bake in the preheated oven at 175ºC for 20-25 minutes, until a baking needle or toothpick inserted in the centre comes out clean.
Let the cakes cool for 10 minutes, then unmold and transfer them to a wire rack. Let cool for another 10 minutes.
Prepare the maple cinnamon glaze by mixing together powdered sugar, vanilla extract, maple syrup, and cinnamon powder. Mix until smooth with a syrupy thick consistency.
Transfer about 2-3 tsp glaze to the fall-themed cake pan, spread out evenly in each cavity. Place each cake onto the glaze, press it down, unmold and flip it over.
Allow the cakes to cool before serving.
