Step 1

Preheat oven to 350 degrees. Grease a 13 X 9" pan with butter and line with parchment. Also make sure that all the ingredients are at room temperature. This is very important.

Step 2

In a medium bowl combine and stir the egg whites, 1/4 cup of milk and the vanilla. Set aside.

Step 3

In the bowl of an electric mixer fitted with the paddle attachment combine the dry ingredients together on low speed for 30 seconds.

Step 4

Add the butter and remaining milk and mix on a low speed until just combined. Increase to medium speed and mix for 1-2 minutes.

Step 5

Scrape the sides of the bowl and begin to add the egg mixture in 2 separate batches, beat on medium speed until it is just combined. (No more than 45 seconds after each addition)

Step 6

Fill prepared pan with batter.

Step 7

Bake for 30-35 minutes, rotating the pan halfway through. You will know the cake is done when a cake tester comes clean when inserted into the center or when you press the top of the cake with your finger and the cake bounces back. Let cool on racks until cooled completely.

Step 8

In a small sauce pan put 1/2 cup (minus 1 tbs) of sugar. Cover the sugar with a little bit of water until the sugar looks like wet sand. Cook on a stove top over high heat until it reaches 248 degrees on a candy thermometer.

Step 9

While the sugar is cooking use a stand mixer with a whisk attachment to whip egg whites on a high speed until they reach soft peaks.

Step 10

Once you have soft peaks add the remaining 1 tbs of sugar and mix on a high speed until the egg whites become stiff peaks. You can keep mixing the egg whites at a high speed until the sugar is done cooking.

Step 11

Once the sugar reaches 248 degrees immediately add it to the egg white mixture. Mix on a high speed for 20 minutes.

Step 12

Now add the room temperature butter and mix on a high speed for 5-10 minutes until the butter is fully combined and the mixture resembles buttercream.

Step 13

Add vanilla and mix until just combined.

Step 14

Once the cake is cooled, use your hands or two forks and to crumble the cake into fine crumbs.

Step 15

Add 1 tablespoon of sprinkles and mix it into cake crumbs. Repeat this until the sprinkles are distributed evenly among the crumbs.

Step 16

In a separate bowl mix the cake crumbs and the buttercream. For every 1 cup of cake crumbs add 1-2 tbs of buttercream. Mix with hands or fork until the buttercream is fully incorporated. You want the mixture to be just moist enough to roll into balls.

Step 17

Using a small ice cream scoop, scoop out a small amount of mixture and roll between cupped hands until you reach the desired round shape.

Step 18

Put balls on a plate and cover with plastic wrap. Place in refrigerator for at least 4 hours.

Step 19

Place coating chocolates in a deep bowl so you will be able to submerge the entire ball in the chocolate. Melt chocolates.

Step 20

Dip lollipop stick into chocolate and then into the middle of a cake ball.

Step 21

Dip cake ball into the chocolate until it is completely covered. Hold it sideways over the bowl and rotate it and tap it so the excess chocolate comes off.

Step 22

When the excess chocolate has dripped off, push the lollipop stick into styrofoam block to dry.

Step 23

Once chocolate is dry, paint the top part of the ball around the stick with piping gel and add sprinkle decorations.

Step 24

Place each pop into an individual mini cupcake liner.
