Preheat oven at 175 C.
Using oil, grease the cavities of a mini-bundt pan or two mini loaf pans or a 7" round tin.
In a large bowl, whisk together pumpkin puree, brown sugar, eggs and oil.
In another bowl, with a whisk mix together all dry ingredients.
Add the dry ingredients to the wet in two batches. Incorporate well to make a smooth batter.
Fill 2 heaped teaspoonfuls per cavity or 3/4 filling each.
Bake mini bundts for 15-20 minutes, or until a skewer comes out clean.
Mini loaf pans may take around 30 minutes and round cake tin around 45-50 minutes. Once golden brown on the top and a tester comes out clean, they are ready to come out of the oven.
Mix all ingredients for glaze with a spoon until it is of drizzling consistency. Add a few drops more milk if required.
When the cakes are still warm, drizzle over them.
Serve warm.
