To make the Buttercream
frosting, cream the room temperature butter and PURE
VANILLA EXTRACT together on medium speed with an electric mixer. Alternate
adding powdered sugar and milk, mixing well on low speed after each addition.
To decorate the cake, frost the entire cake smoothly with 11/2 Cups of
plain white Buttercream frosting 2. Divide the remaining frosting into
3 separate bowls - 11/2 Cups for red, 1/2 Cup each for blue and plain.
To color the frosting, dip a clean toothpick into the blue or red paste
and stir into the frosting , mixing well with a spoon 3. If you need to
add more for the perfect color, use a clean toothpick. You will need quite
a bit of red for the perfect color–we used about 1/3 of a large jar. Start
with the blue frosting, thin with 1 TB. milk. Using a round tip (we used
a #4 - the standard round tip that comes with a grocery store frosting
kit) on a pastry bag, make a blue square in the upper left corner of the
cake. The blue square should be fairly large–four red stripes will touch
the blue square and three red stripes will be below it. By thinning the
frosting, the lines of frosting will blend together to cover the corner
evenly. The trick is to squeeze the pastry bag with your right hand and
guide the stream of frosting with your left hand. For the corner, make
an outline of the blue square and then, squeeze the bag continuously,
drawing along the square and working your way to the center. 4 For the
red stripes, use a medium star tip (we used a #18 - again, about the same
as a grocery store kit) on a pastry bag and carefully make 7 red stripes
made of stars. This is a bit time consuming, but not hard. Practice a
few stars on a piece of paper before moving to the cake. We made each
red stripe 3 stars wide 5. For the flag’s stars, use 1/2 Cup of the buttercream
frosting and a round tip. If you have a smaller tip, it is a bit easier
(we used a #3). Thin the frosting with 1 TB of milk and squeeze to make
the stars. Draw the stars just like you would on a piece of paper–they
don’t need to be perfect 6. As you can see, our cake doesn’t have 13 stars,
and it still looks as good as it tastes.
