Pistachio Bliss Bundt Cake

Preheat the oven to 350 degrees F. Butter and flour a 10 or 12-inch fluted bundt pan.
In a large mixing bowl, combine the cake mix, instant pudding powder, eggs, 7up soda, vegetable oil, and almond extract (if using); mix with an electric mixer or whisk vigorously for 2 minutes until well blended. Gently fold in the chopped pistachios.
Pour the batter evenly into the prepared bundt pan.
