When you can slice right through a rainbow cupcake and see the
rounded (not sunken) top and layers of colors, that is success right
there!

And normally, I’m not a fan of sprinkles, but these little
confetti/sequin sprinkles, are just fun! I do like dots better than
lines though.

If you couldn’t tell, I was having a lot of fun photographing these!
Too many pictures to choose from, but the awesome thing is, I’m going
to show you how to make these, and I’m sharing TWO TRICKS to baking the
perfect cupcake!

Let’s start with these rainbow cupcakes. It’s a boxed mix people!
Grab a white cake mix from the store, mix it up with the ingredients on
the label (do the egg whites over whole eggs, if there are two
options), then divide the batter into 6 bowls.
Using food coloring or paste, mix these 6 colors: red, orange, yellow, green, blue, and purple.

This next part may be an extra, unnecessary step, but I’m OCD to getting as even of layers as I possibly can…
Put each batter into a zip-top sandwich bag and cut off one corner to
pipe with. It’s best if you cut one bag at a time, so the cake
mix doesn’t spill out as you layer the batter.

Squeeze the colored batters into paper lined cupcake tins in the
order the rainbow: red, orange, yellow, green, blue, and purple. Smooth
each layer of the batter as close to the edges as you can with your
finger.
You can optionally spoon the colored batters into the cupcake liners
and spread the batter with your finger to save time and plastic bags.
You can see the succession of layers below.

Now, the trick to getting peaked cupcakes (or muffins) is to first,
FILL EACH CUPCAKE MOLD 2/3 to 3/4 full. I HIGHLY recommend only doing
18 cupcakes even when your boxed cake mix says it makes 24 cupcakes.
The next trick is to BAKE AT 400 degrees Fahrenheit for 11 to 13
minutes. Depending on the batter and your oven, it may take less or
more time. You want the cake to spring back when touched lightly.
Baking
cupcakes at a higher temperature forces the cake to grow upwards and
bake quicker, so it doesn’t have time to spill over the top and get
sunken in the middle. I do this with EVERY cupcake and muffin
recipe. Times may vary depending on the type of batter, but the 11
minute bake time is a great gauge to start checking the doneness from.
Voila! Beautiful cupcakes rounded over the top of the cupcake liner,
ready to be frosted. Baking them this way also helps you use less
frosting to get that towered look on top!
Rainbow Cupcakes
- 1 (15.25oz) box white cake mix (I like Pillsbury)
- Ingredients
for cake mix as stated on box (Use only egg whites if that is an
option. My box said 1¼ cup water, ⅓ cup oil, 4 egg whites.)
- Red, Orange, Yellow, Green, Blue, and Purple Food Coloring/Gel
- 1 recipe The BEST Cream Cheese Frosting
- ½ (8oz) tub whipped topping (Cool Whip)
- Rainbow Sequins/Celebration Confetti/Rainbow Sprinkles
- Prepare
cake mix according to directions on the box (do the egg whites version
over whole eggs, if there are two options), then divide the batter
evenly into 6 bowls.
- Using food coloring or paste, mix these 6 colors: red, orange, yellow, green, blue, and purple.
- Prepare cupcake pan(s) with 18 paper liners.
- Put
each batter into a zip-top sandwich bag and cut off one corner to pipe
with. It’s best if you cut one bag at a time, so the cake mix doesn’t
spill out as you layer the batter.
- Squeeze
the colored batters, one at a time, into the paper liners in the order
the rainbow: red, orange, yellow, green, blue, purple. Smooth each layer
of batter with your finger, getting as close to the edges as possible.
*TIP: Do all the red batter first, then all the orange, etc.
- Once
all the layers are finished, bake the cupcakes at 400 degrees
Fahrenheit for 11 to 13 minutes. Baking them at a higher temperature
forces the cake to grow upwards and bake quicker, so it doesn’t have
time to spill over the top and get sunken in the middle.
- Prepare The BEST Cream Cheese Frosting.
Beat in half of an 8oz tub of whipped topping with a handheld
electrical mixer. Fit a piping bag with a coupler (no tip or band) and
then fill the bag with the frosting.
- Pipe
the frosting on top of each cupcake from the outside in towards the
middle. Sprinkle with rainbow sequins. (*Store cupcakes in an airtight
container in the refrigerator up to 4 or 5 days.)
