It is a little time consuming when you are cooking it from scratch, several hours, but you don't have to make it all in one day.
The cake you will be making is large so be ready to share :)
For the dough:
1 bottle of light beer, 12 oz
400 gr cold butter (you can use either salted or unsalted. I tried to bake with both and I liked the salted one better)
4 cups all purpose flour
For the custard cream:
4 cups milk
5 large eggs
4 tablespoon flour
2 1/2 cup sugar
1 table spoon vanilla
Step 1. Make the dough.
Add the flour in a mixing bowl, add the butter by cutting it with the knife into flour until you will get an even crumbled texture.
Step 2. Make the custard crème.
Mix the eggs and sugar in a mixing bowl. Add the flour and mix all together.
Heat the milk in a pan but do not boil. Add small portions of the hot milk to the mixing bowl, stirring as you add it, until it is all added.
Put the blended mixture into a large pot and cook on medium heat, stirring constantly, until it boils. Turn the heat off, add and stir the vanilla into the mix. At this point your custard cream should be nice and smooth but if it is not just use the blender or mixer to make it an even texture. Leave your crème to chill.
Step 3. Bake your cake layers.
Preheat your oven to 400'F. Take out one piece of the dough, and roll it on a floured surface to the rectangular shape. Apply even pressure when rolling and add flour as you go to avoid sticking to the surface. Make it as thin as about 1/8". Poke holes all over it with the fork to avoid air bubbles while baking.
Step 4. Arrange the cake.
Prepare a cutting board large enough to accommodate the layers. Place first layer on the board and generously spread the custard on top. Cover with the second layer and repeat with crème. Continue in the same manner with all 7 layers. Spread the last portion of custard on top of 7 layer. Spread the crumbled layer on top.
When you take the weight off your cake it should be about 1 1/2" to 2" thick. Now you can cut the sides to make it a perfect rectangular. I love to eat the leftover sides, they are the sweetest :)
