With mixer on low speed, mix in dry ingredients alternating with milk.
Pour half of the batter into the bundt pan.
Gently pour the pie filling on the batter making sure to not take it to the sides. Essentially you want to make a ring along the center of your batter with it.
Next pour on 2 cups of the thickened ganache over top, again ensuring to not let it touch the sides. The ganache should be super thick and not runny.
Top with the remaining batter.
Bake for 30-40 minutes until a wooden skewer inserted in the center of the bundt comes out clean/just a few moist crumbles.
Cool for 15 minutes and invert onto a cooling rack. Allow to cool completely.
To decorate, heat up the remaining 1 cup of ganache until it’s of a thick pourable state (like syrup).
