Step 1

For the cake, preheat the oven to 350 degrees Fahrenheit. Grease a 10-inch tube pan with butter and coat with flour. Shake out excess flour.

Step 2

In a large bowl, whisk together yellow cake mix and pistachio pudding mix. Form a well in the middle and pour in the eggs, water, oil, almond extract, and food coloring. Beat the ingredients at medium speed for about 2 minutes, or until well-combined.

Step 3

Pour the batter into the prepared pan. Bake for 50 to 55 minutes. The cake should spring back when pressed lightly.

Step 4

Let the cake cool in the pan for 15 minutes. Flip it over onto a wire rack and let cool completely.

Step 5

Meanwhile, prepare the frosting. Whisk together Cool Whip and pistachio pudding mix until smooth and fluffy.

Step 6

Frost completely cooled cake with pistachio frosting. Slice and enjoy!
