Step 1

How To Make Strawberry Cake:Preheat oven to 350*. Line 2 – 9 inch round cake pans with parchment paper and set aside.

Step 3

In a mixer add the cake mix, flour, sugar, sour cream, water, oil and Jell-o mix. Mix until combined. Then add 1 egg white at a time. Once all the eggs are in, mix for about 90 seconds.

Step 5

Divide the cake batter between the 2 cake pans. Bake for about 22-25 minutes until a knife comes out clean. If you need to add more time, do it in 3-minute increments.

Step 7

Let cool completely. Put one cake on a plate or cake stand. I like to flip the cake into my hand and remove the parchment paper and then put it baked side down on the cake plate. Trim the cake to make it even. (You can place the cakes in the freezer to handle them easier.)

Step 11

How To Make the Vanilla FrostingUse the paddle attachment on your stand-up mixer and beat the butter on medium speed until smooth.

Step 13

Turn the speed to low and slowly add the powdered sugar until it is mixed in.

Step 15

Slowly add the vanilla and heavy cream. Turn the mixer up to medium speed and mix for 1 minute until creamy.

Step 17

Add additional heavy cream, if you desire a creamier frosting.

Step 23

How To Make The Strawberry Eclair CrumblePulse the Golden Oreos in a food processor until they are crumbly.

Step 25

Mix together the crumbled Oreos, butter, and the strawberry Jell-O powder.

Step 27

Set on a cookie sheet lined with parchment paper and let it "dry" for about an hour.

Step 31

How To Assemble the Strawberry Shortcake Eclair CakeSet one of the cakes on a plate. Add about 1 cup of icing and top it with the other white cake.

Step 33

Start frosting the sides with an icing spatula. Once the sides are covered, add frosting and spread until the whole cake is covered.

Step 35

Place some wax paper under the cake plate. Add some of the strawberry eclair crumble into your hand and place it along the sides of the cake. Go completely around the cake. You can scoop up what falls on the wax paper.

Step 37

Add the crumble to the top of the cake until as much of the white frosting is covered.

Step 39

Serve and enjoy!
