Infinite Cake Recipe

Simon baked the whole cake himself, I only helped with the eggs and the oven. Scroll down for the actual recipe!

It was Simon’s birthday yesterday and we whipped together another geeky bake! This time, Simon based his geeky bake on the famous Missing Square Puzzle, involving two arrangements made of similar shapes in slightly different configurations. Both arrangements seem to form a 13×5 right-angled triangles, but one has a 1×1 hole in it (hence the “paradox” is that depending on the arrangement, the area of the triangle seems to change).

Have you figured it out? Below is Simon’s explanation:

We also did our traditional presents quest. “You know what would be cool? Branching paths,” Simon asked me to level up in my quest making skills, meaning that every question can sometimes have more than one answer, creating branches. I was afraid I would mess everything up, unable to keep track of the branched sequences of hidden presents all over the apartment, but it actually turned out pretty neat. I’m sharing the questions below. To turn this quiz into a quest, just add descriptions of where you hid the presents to the correct answers and descriptions of where you hid nothing to the incorrect ones. I based my questions on this really awesome resource for computer history, called The correct answers are marked in bold:

Cake Recipe

If you want to know the actual recipe, we used the same dough as in last year’s geeky bake, the Rubik’s Cube Cake, our favorite Japanese chocolate-matcha flavor:

270 mlmilk (we used unsweetened oat milk)
9 full tbsunsweetened raw chocolate powder/cocoa
6 tbsmatcha (Japanese green tea powder)
210 gsoft butter (unsalted)
330 graw sugar
1 1/2 tsvanilla extract
165 mlfresh whipping cream
300 gflour (we used gluten free flour)
7 gyeast

Warm up the oven for 165° Celsius (ca.330° Fahrenheit). Warm up the milk until it’s lukewarm and divide it into two bowls (pour 2/3 into one bowl and and 1/3 into the other). Whisk the chocolate powder into the large portion of milk and matcha powder into the smaller portion and set both aside. Take a big mixing dish and mix together in this order: butter, sugar, vanilla extract, eggs (beat/whip the eggs up with in a separate dish first), cream. Add the flour last. Separate your dough into two bowls again, 2/3 into one bowl and 1/3 into the other. Add the chocolate-milk mixture to the first bowl and the matcha-milk mixture to the second one and stir carefully. Pour most of the chocolate dough into the mold, then pour the matcha dough, and then the rest of the chocolate dough in top. Bake for about 45 minutes or until a wooden pricker you poke the cake with comes out dry.
