Grease a 6 cup capacity bundt pan & preheat the oven to 350°F
First prepare the pecan filling by combining the brown sugar, pecans & cinnamon together in a small bowl ~ reserve
Combine the plant milk with the vinegar & extracts
Combine both flours, sugar, baking soda, baking powder & salt together in a large mixing bowl, whisk to combine evenly
Pour in the plant milk & oil & whisk to a smooth batter (approx 20 strokes)
Pour half of the batter into the greased pan then sprinkle the pecan filling evenly over the batter
Now pour the remaining batter over the pecan filling
Bake immediately in a preheated 350°F oven for 30 minutes then turn the oven down to 300°F & bake for another 20minutes or when a toothpick inserted into the center comes out clean.
Cool in the pan then serve warm!
