Let’s break down the process into easy-to-follow steps.

Step 1: Prepare Pudding Mixture. In a large bowl, beat the milk, sour cream, instant vanilla pudding mix, and orange zest on low speed until thickened.

Step 2: Fold in Whipped Cream. Fold in the whipped cream (that you’ve whipped separately) into the pudding mixture. This creates a light and airy filling.

Step 3: Assemble First Layer. Place half of the cubed angel food cake in the bottom of a 3-qt. glass bowl.

Step 4: Add Strawberries and Pudding. Arrange a third of the strawberries around the side of the bowl and over the cake. Top with half of the pudding mixture.

Step 5: Repeat Layers. Repeat the layers once more: cake, then pudding.

Step 6: Top with Remaining Berries. Top with the remaining strawberries.

Step 7: Chill. Refrigerate for 2 hours to allow the flavors to meld and the trifle to set up slightly.

Step 8: Serve. If desired, top with additional sweetened whipped cream just before serving.

These are easy to follow instructions.
