Preheat oven to 325℉.
Generously grease a 10 inch bundt pan. Set aside.
In a large bowl, stir together cake and pudding mixes.
In the bowl of a stand mixer whisk together orange juice, oil, eggs, Cointreau and 1 teaspoon orange extract until well combined.
Reduce speed and slowly add dry ingredients.
Whisk on high speed until you have a smooth, lump free batter.
Pour batter into prepared bundt pan.
Bake in preheated oven for 50 to 60 minutes, or until a toothpick inserted into the cake comes out clean.
Let cool in pan for 10 minutes.
While cake is cooling, heat orange juice, sugar, Cointreau and butter in a saucepan over medium heat for two minutes until mixture bubbles. Remove from heat and stir in 1 teaspoon orange extract.
Drizzle over cake, pulling cake away from sides of the pan to allow glaze to trickle down the sides of the cake.
Allow cake to soak up the glaze for 10 minutes. When all the glaze has been soaked up into the cake, turn out onto a cake plate to cool completely.
