one box of white cake mix and ingredients to make it
food coloring
3cupsof whipped cream I used Cool Whip
2packages of Jello White Chocolate Instant Pudding . prepared according to package instructions.
Instructions
whip up one white cake mix according to the package instructions, then divide the batter into 6 cups.
Using any cake gels, food coloring or icing gels, color up the white batter.
You are going to make two cakes, so grease up two 8 inch cake tins.
Pour half of your red batter into the first one, reserving half for the second cake. Do not push it around, just let it move out naturally to the edges.
Pour the orange right in the middle of the red (again, only half of your batter, save half for the second cake) and that's going to push the red even closer to the edge.
Keep going with the yellow, green, blue and purple, pout half of each into the very middle until you see a cake like below.
You can wiggle the pan side to side very slightly to help the batter move out.
Tap the pan on the table or counter lightly to remove bubbles.
Repeat with your second cake.
Bake the cakes according to the package instructions, cool and remove. You can at this point freeze them if you aren't making the trifle right away.
Prepare the pudding mixes according to the package instructions and let set.
The secret to the rainbow stripes is shown in the photos. It's all about the direction you cut the cake!
Slice your cake exactly as shown in the photos and you will have gorgeous rainbow slices.
Place the best looking center pieces that are full rainbows on the edges like shown in the photos.Fill in the middle of the trifle with the pieces of cake that aren't full rainbow slices.
To make each layer, place the cake layers down, put a third of the white chocolate pudding on top, then a third of the whipped cream. Then start another cake layer and repeat two more times.
Top the whipped cream with leftover rainbow cake crumbs.
Refrigerate at least 6 hours but it's far better if you make this the day before and refrigerate it overnight.
Notes
Calories for this will depend on what cake mix you use and if you use only egg whites or not! You will have to calculate this one on your own for accurate numbers.
