Preheat the oven to 350F (180C).
Add the chopped pecans to a cookie sheet and spread into an even layer. Bake in the preheated oven for 8 minutes, or until the appear toasted.
Remove from the oven and turn down the temperature to 325F (170C).
Grease and flour the bundt pan, being sure to get into every crease. Alternatively, brush the pan with pan release (this is what I did).
In a medium bowl, whisk together the flour, cinnamon, ginger, nutmeg, cloves, baking soda, baking powder and salt. Set aside.
In a separate large bowl, whisk together the oil, granulated sugar, brown sugar, whisked eggs, vanilla extract and rum extract.
Then whisk the dry ingredients into the wet ingredients. I typically do this about ½ at a time. Once you no longer see lumps, stop mixing. Be sure not to overmix the batter.
Add the toasted pecans to your prepared pan.
Then spoon the batter into the prepared pan and smooth the top.
Bake in the preheated oven for about 50-60 minutes, or until an inserted toothpick comes out clean. You should start to see the edges of the cake pull away from the outside of the pan. If you're unsure, I'd recommend baking for a few extra minutes to ensure that the cake is fully baked.
Cool in the pan about 20 minutes, then carefully invert the pan so that the cake slides out onto a wire rack.
