Preheat oven to 350 °F. Spray three 6-inch round cake pans with non-stick spray, line the bottom of each pan with parchment paper and spray again. Set aside.
In a medium-size bowl, whisk and stir together the cake mix, all-purpose flour, and salt. Set aside.
In the stand mixer bowl fitted with a paddle attachment, beat the butter, oil, and sugar on medium-high for 5 minutes.
Add eggs, one at a time to the stand mixer bowl and beat on medium until well incorporated.
Turn the mixer on low and add half of the flour mixture to the butter mixture until fully incorporated.
Add the vanilla and milk, beat on low until incorporated. Scrape down the sides of the bowl. Finish by adding the remaining flour mixture and mix on medium for another 30 seconds.
Evenly distribute the cake batter among the three cake pans and bake for about 30-35 minutes or until a toothpick inserted into the center of each cake comes out clean or with just a few moist crumbs.
Remove cakes from oven and let cool in pans for 10 minutes before inverting onto cooling racks to cool completely. Wrap cakes in plastic wrap and place into the freezer to chill for 30 minutes.
In the stand mixer bowl fitted with the paddle attachment, beat the butter on high until light and fluffy, about 5 minutes.
Turn the mixer to low, gradually add powdered sugar, followed by the cream. Then add vanilla extract and salt. Mix until incorporated completely. Scrape down sides of the bowl.
Turn the mixer to medium-high and beat the buttercream for about 5 minutes until light and fluffy. Scrape down sides of the bowl. Turn the mixer on low and mix for 2 minutes to push out any air bubbles.
Place 1 cup of the white buttercream into a piping bag with an Ateco #804 round tip.
In two small bowls, add ⅔ cup of buttercream to each bowl. Then color one bowl of buttercream with ivory gel food color and the other bowl with brown gel food color.
Next place some ivory buttercream into a piping bag with a small round tip and save for later.
Prepare a piping bag with a coupler and a grass piping tip, place the prepared piping bag into a cup to support it. Add some white buttercream to line ⅓ of the bag, then add the ivory buttercream to another third of the bag and finally add the brown buttercream to the last third of the bag so this way all three colors will be used to pipe at one time.
Layer one vanilla cake, cut side up onto cake board. Add a 2/3 cup of vanilla buttercream over the cake. Place another cake layer cut side down over the top. Repeat process for another layer. Crumb coat and freeze for 30 minutes.
With a small serrated knife begin to crave the chilled crumb-coated cake into a dome shape. Shave any sharp corners to make smooth then crumb coat the dome-shaped cake with a thin layer of buttercream all over the whole cake. Then freeze for 20 minutes to set the buttercream.
With the piping bag filled with white buttercream, pipe a heart shape as the face of the Hedgehog at the top section of the cake then pipe a belly of the Hedgehog. Then pipe a mound of buttercream to create the nose.
Smooth the buttercream with an offset spatula. To make perfectly smooth, add a drop of water to the spatula and use that to smooth the buttercream. Don't make the buttercream to set or the fondant decorations won't stick to it. Wipe any buttercream off the spatula before wetting it again and wiping the buttercream smooth. Place the cake back into the freezer for 10 minutes.
Begin to pipe the fur of the Hedgehog with the tri-color buttercream piping bag. Use slight pressure to pipe fur all over the cake minus the face and belly of the Hedgehog. Set the cake aside.
On a silicone mat, start with purple fondant to make the number 2, roll the fondant into a rope and curl the edges to roll into itself. Set the number aside to dry.
Next, make the party hat, start with a cone shape with light blue fondant, then add a small round ball of blue on top of the hat and add a thin rope of blue to the bottom of the cone. Roll the green fondant thin to cut out small dots. Use a small paintbrush and a little water to attach the green dots. Set aside to dry.
Roll the black fondant out to cut out small circles for the eyes. Then roll a small amount of black fondant to make a nose for the Hedgehog. Next, roll out pink fondant to make pink cheeks. Add small dots to make the white of the eyes for the Hedgehog. Set aside.
Place the eyes and cheeks on to the face. Then use a toothpick to attach the nose. Place the number 2 onto the belly, use a small amount of buttercream to attach the number. Insert a toothpick into the party hat and insert it into the top of the Hedgehog.
Pipe two ears, six toes and two arms holding on to the number with the ivory buttercream. Serve at room temperature and Enjoy!
