Red Velvet Trifle

Step 1
Preheat the oven to 350 degrees F (175 degrees C). Line a 10×15-inch jelly roll pan with parchment paper, then spray lightly with cooking spray.

Step 2
Combine cake mix, water, oil, and eggs in a large mixing bowl. Beat with an electric mixer on low speed for 30 seconds, then on medium speed for 2 minutes. Pour batter into the prepared pan and smooth to even out.

Step 3
Bake in the preheated oven until a toothpick inserted into the center comes out clean, about 20 minutes. Remove from the oven and let cool completely, about 30 minutes.

Step 4
When the cake is almost cooled, whisk milk and pudding mix together for 2 minutes. Let sit until set, about 5 minutes.

Step 5
Meanwhile, cut the cooled cake into 1-inch cubes.

Step 6
Place 1/2 of the cake cubes in the bottom of an 8-inch trifle bowl. Layer with 1/2 of the pudding and 1/2 of the cherry pie filling. Repeat layers once more. Refrigerate for 4 to 8 hours before serving.

Step 7
Garnish with whipped cream.
