Step 1: Bake the cake layers

Picture of Bake the cake layers
The cake itself is made from scratch to make three 9x9 layers. The cake recipe is from here.

- 3 cups packed brown sugar
- 1 cup butter or margarine, softened
- 4 eggs
- 2 teaspoons vanilla extract
- 2 2/3 cups all-purpose flour
- 3/4 cup baking cocoa
- 1 tablespoon baking soda
- 1/2 teaspoon salt
- 1 1/3 cups sour cream
- 1 1/3 cups boiling water

DIRECTIONS
In a mixing bowl, cream brown sugar and butter. Add eggs, one at a time, beating well after each addition. Beat on high speed until light and fluffy. Blend in vanilla.

Combine flour, cocoa, baking soda and salt in other mixing bowl.

Add dry mix alternately with sour cream to the creamed mixture. Mix on low just until combined.

Stir in water until blended.

Pour into three greased and floured 9x9 baking pans.

Bake at 350 degrees F for 35 minutes. Cool in pans 10 minutes; remove to wire racks to cool completely.

Step 2: Make Raspberry Sauce

Chocolate needs raspberries or at least that's my opinion.

Thaw out 8 - 10 oz. of frozen raspberries or rinse off fresh ones.
Stir in 3 - 4 spoonfuls of raspberry preserves.

Mix it up, taste, and adjust accordingly.

Step 3: Spread on Raspberry and Layer the Cake

Put a nice thin layer of the raspberry mix on top of the bottom layer and add the next layer. Repeat.

Step 4: Cut Cake in Shape of Pi

Step 5: Add Frosting

I only added frosting to the top so that the pi shape would be clearer and easier to see. You can frost the whole thing if you want.

Frosting recipe:
- One stick of butter at room temperature
- 1/2 package of powdered sugar
- splash of Grand Marnier
- a few ounces of half-and-half

Start by blending the butter and powdered sugar. Then add the splash of Grand Marnier for flavor. Finally, slowly blend in the half-and-half until the frosting is at the consistency you like.

Now eat!

FUN FACT!!!!! Pi is rounded to 3/7. The most digits ever found in pi was over 3 BILLION!!!! And if each 6 didgts would be a centimeter, it would lap the entire PLANET 2 and a 1/2 times! ( Yes I did the math)
and if you were running around the universe at light speed it would only take you half a planctime to travel pi
actually pi's every 6yh digit is equal to a centimeter it would span the entire universe and more (theoritically)
pi goes on forever, so the line would too

Happy Pi Day all.
buckbecky4 years ago
We do pi day in 6th grade math class. Many pies are eaten in honor of pi. The circular shape of a pie helps students remember pi goes with area of a circle.
FUN for all!
Bit of an oxymoron, ehnit? :)
I just noticed this 'ible today, and wanted to tell you that it's awesome!

I also think this cake would look good with some some candles. Attached is an artist's interpretation of what this might look like.

FUN FACT!!!!! Pi is rounded to 3/7. The most digits ever found in pi was over 3 BILLION!!!! And if each 6 didgts would be a centimeter, it would lap the entire PLANET 2 and a 1/2 times! ( Yes I did the math)

There's not a rational number to represent the square root of an negative number.
OH NO TIME PARADOX!

A "pi cake" seems like a rather irrational pursuit. But a tasty one! ;)

*ducks*
*Throws imaginary pie*
Does this mean we need an "i" cake to go along with the pi cake? While we're at it, how about e, and the square root of 2?
