• Cut the strawberries into quarters. You should then have enough to make the red stripes. Add to the bowl of strawberries the vinegar and sugar. Mix carefully, and refrigerate.
• Using a spatula, spread some of the sweetened condensed milk on a torte. Make sure you cover the whole thing, You should use about a quarter of the can.
• Put another torte on top of that one, and put down evenly with your hands so the layers are stuck together.
• Put some of the sweetened condensed milk on this layer as well.
• Put the third layer, and again, press down evenly.
• On the third layer, spread the Nutella all over.
• Put the fourth layer, and again, press down evenly.
• Cover this layer with more of the sweetened condensed milk. You should still have some left over that you can make Thai Iced Coffee or Thai Iced Tea.
• Put the last layer, and cover this with plastic wrap or wax paper. Get something large, like a cookie sheet, and carefully put that on top of the plastic. Weigh that down as well with a heavy pot or sugar/flour canister. Let it sit for a few hours.
• If you can, put it in the refrigerator and let it set over night.
• When it is set, prepare the Sour Cream Buttercream Frosting.

For the Sour Cream Buttercream Frosting

• In a standing mixer, put the butter, and beat until it is creamy.
• Add half of the sour cream.
• Start adding the powdered sugar, about half of the box, and mixing as you go along.
• Stop the mixer and wipe down the sides of the bowl.
• Add the vanilla and mix. Stop the mixer and wipe the sides of the bowl.
• Add the rest of the sugar, and mix. Use your judgment to determine how much of the sour cream you need to add to get a good consistency. This will depend on how humid it is in your kitchen, and how liquid your sour cream is.

Finish the Cake

• Remove the covering from the cake, and spread the frosting on top. Be generous.
• Use a chop stick or a clean pencil top to draw 12 evenly spaced line on the cake. Those will form the 13 stripes.
• Mark off a rectangular region in the upper left hand quadrant. This will be for the stars.
• Carefully place the strawberries in every other area between the lines, starting at the bottom, and also at the top. You should have 7 red lines, and 6 white ones. Do not put strawberries in the area designated for the stars.
• When you have completed the stars, count out and place the 50 blueberries in the designated blueberry area.
• Refrigerate the cake until ready to serve.
• When you serve it, you will want to use scissors, as a plain knife will not cut through this. It's kind of like a really, really big wafer cookie.
