In a medium mixing bowl, mix cake mix and pudding until combined. Make a well in the center. Add the liquid ingredients. Mix on low until blended, then on med/high for 3 minutes. Fold in the chocolate chips.
1 cup chocolate cake mix, 3 tbsp instant chocolate pudding mix (dry), 2/3 cup sour cream, 1/4 cup butter, 1/4 tsp almond extract, 2 eggs, 1/3 cup chocolate chips
Spoon batter into prepared pan. Be sure to spread it evenly throughout the pan! Cover tightly with foil.
Place trivet in the inner cooking pot and pour in one cup of water. Using a sling, lower the Bundt pan into the cooker. Cover, turn steam release valve to "closed" and press Desserts. (Low Pressure) Set time for 25 minutes. After cooking cycle has ended, do a quick pressure release and remove pan to a cooling rack.
Cool for 10 minutes in the pan and then turn out onto a cooling rack to add ganache and finish cooling.
For the ganache
In a small saucepan, bring the heavy cream just to a boil. Place the chocolate chips into a medium bowl and pour the hot cream over the top. DO NOT STIR. Allow to sit uncovered for 10 minutes. After the cream has cooled for 10 minutes, gently stir until the melted chocolate and cream blends into a smooth, shiny chocolate ganache.
1/4 cup heavy cream, 1/4 cup chocolate chips
Place a baking sheet under the wire rack and pour the chocolate ganache over the cake. Save the excess ganache to use as frosting, or pull it back out and pour it over the cake for a second coat.
Allow ganache to set, then slice and serve! Grab some cold milk because it's rich!
