Step 1

Preheat oven to 350 degrees F. Butter and flour a 10 or 12-inch fluted bundt pan.

Step 2

In a large bowl, whisk together the cake mix, instant pudding powder, eggs, 7up soda, vegetable oil, and almond extract (if using); beat with an electric mixer or whisk vigorously for 2 minutes, until combined. Fold in the pistachios.

Step 3

Pour evenly into the prepared pan.

Step 4

Bake for approximately 40 minutes or until a toothpick in the center comes out clean. Remove from oven and cool 10 minutes, then run a dull knife along the edges to loosen. Then allow to cool completely.

Step 5

Turn cake out onto a wire rack or plate; dust with powdered sugar.

Step 6

Slice and serve!
