Say "I love you" with homemade cake decorating designs for Valentines Day. This is not a complicated cake to make. Just prepare the marshmallow fondant a day ahead.
Here are some more Valentines
Cakes
and Valentine Cupcakes.

What you'll need for Valentine Cake Decorating Designs:
Begin by placing the first heart cake layer on the cake board. Fill
with buttercream icing and repeat with the next layer.
Frost the
outside of the cake with buttercream icing.
Knead the marshmallow fondant until pliable. Cut of a palm-sized piece
and set aside to make the flowers and leaves.
Tint the remaining fondant a pale lavender using the violet food paste.
Measure the top of the heart cake at its widest point. Now measure the
height of the side of the cake. Double this measurement and add it to
the cake top measurement. You will need to roll the fondant out to at
least this measurement to cover the entire cake.
Roll the fondant out on a surface dusted with
either confectioners
sugar or cornstarch using the rolling pin. Fold the entire piece in
half horizontally and again vertically. Line up the center of the
fondant with the center of the cake. Unfold the fondant and smooth the
fondant out with your hands, beginning with the center of the cake and
continuing out and down to the bottom of the cake.
Gather up the excess
fondant and set aside in plastic wrap. Using the pizza cutter,
trim the fondant all
around the cake where it touches the cake board and remove the excess
fondant.
Now for the embossed cake decorating designs:
Using the ruler, find the center of the cake and hold the ruler
horizontally across the middle. Use the smallest serrated edge of the
metal triangle to emboss the fondant all the way across the top of the
cake. Repeat this process along the opposite side of the ruler.
Continue
moving the ruler down below the previous line and emboss the cake.
Repeat this process moving from the center of the cake to the top of
the cake.
Now hold the metal traingle so this same serrated side
lines up with the end of the embossed line on the top of the cake. The
triangle should sit flat on top of the cake board. Now turn the metal
triangle towards the cake until you emboss the fondant on an angle with
the same serrated edge.
Repeat this process all around the cake.
Now,return to embossing the top of the cake, only this time, hold the
ruler in the opposite direction, so that the embossed lines will be
perpendicular to the lines you already made.
Take the excess lavender fondant back out and add more violet food
paste to it. Knead the color throughout. Pull off about 1/3 of this
fondant and roll it out to 1/4" thick.
To make the violet ribbon roses,
use the ruler and pizza cutter to cut out strips about 3/4" wide. Fold
this strip in half to make the width one-half the size. Start at one
end of the strip and roll the strip up with the folded edge facing up,
making each wrap around further down the flower.
Squeeze the bottom of the flower together with your fingers and trim
off the excess fondant. Make six flowers and set them aside.
Take out the uncolored, reserved fondant. Pull off a golf ball sized
piece to make the leaves and set aside. Roll out the remaining white
fondant and repeat the same procedure as above for making the ribbon
roses, only this time, make the width 1". Make 2 flowers
If you have other cake decorating design ideas in mind, you can make
more or less flowers. There will still be fondant left over to add
more.
Take the remaining white fondant and tint it with the green food paste.
Knead it throughout. Pull off a small piece and roll it into a ball.
Flatten it with your fingers and shape it like a football. Use a knife
to mark the veins. Make as many leaves as you like.
Wet the bottom of the flowers and leaves
and arrange them on the cake as shown.
Take the remaining violet-colored fondant and roll it out. Cut out 1"
wide strip and twist the strips around. Place the strips around the
base of the cake and smooth the ends of the strips together with your
fingers.
Complete the cake decorating designs by combining lemon extract and the
pearlized dusting powder together in a bowl. Use the brush to apply the
mixture to the entire cake.
