Zest 1 of the fresh lemons. This should give you 1 tablespoon of zest which will be mixed into the cream cheese.

Add the softened cream cheese and powdered sugar to a medium-sized (2-3 quarts) mixing bowl. Use a handheld mixer on medium-low speed to mix the cream cheese and powdered sugar until smooth, about 1 - 1 ½ minutes. Add the lemon zest and continue to mix just until well incorporated.

In a separate mixing bowl, use either a handheld whisk or a handheld mixer on low speed to mix the cold milk and instant pudding mix until the pudding begins to thicken up.

Once the pudding has reached the desired consistency, add half of the pudding to the cream cheese mixture. Use a handheld mixer on low speed to combine the pudding and cream cheese until smooth, then add the remaining pudding and continue mixing until smooth.

In the bottom of a trifle dish, create a single layer of 1-inch cake cubes.

Spoon ½ of the pudding mixture over the layer of angel food cake layer. Smooth the pudding with an offset spatula or silicone spatula.

Evenly sprinkle 1¾ cups of the blueberries over the pudding layer.

Repeat the layers of angel food cake, pudding, and blueberries.

Evenly spread the thawed whipped topping over the top berry layer. Cover and chill in the refrigerator for at least 1 hour.

Just before you're ready to serve, slice the remaining lemon either into quarters or into slices. Neatly arrange the sliced lemon in the center of the whipped topping.

Arrange the remaining blueberries around the edge of the whipped topping. You can also scatter a few berries around the lemons. Keep refrigerated until you are ready to serve.

Be sure you cut the cake cubes in uniform size. Try to fit them tightly in the bottom of the dish to form a sturdy base for your trifle. You don't want your Cool Whip and pudding to sink through your cake cubes!

If you accidentally smear some of the pudding or Cool Whip onto the sides of your trifle bowl, you can use a clean paper towel to wipe it off.

You can arrange the lemon slices in a layered, rounded fan shape or a pinwheel shape on the top of the trifle. It's entirely up to you! Be creative!
