Step 1

Preheat the oven to 350 degrees. Spray a 10- or 12-cup bundt cake pan with baking spray and set aside.

Step 2

In the bowl of an electric mixer fitted with the paddle attachment, add the cake mix, pistachio pudding mix, sour cream, vegetable oil, eggs, vanilla, and water. Beat on medium speed for two minutes

Step 3

Fold in the chopped pistachios.

Step 4

Pour the batter into the prepared pan. Bake for 45-50 minutes, or until a toothpick inserted into the cake comes out clean. Allow the cake to cool for 20 minutes before turning it out onto a cake plate to cool completely.

Step 5

Once the cake is cool, whisk together the glaze ingredients. The glaze should be the consistency of glue. Gently pour it over the top of the cake, encouraging it with a small spoon to drip over the sides. Sprinkle with the reserved chopped pistachios and enjoy!
