By replacing a bit of the all-purpose flour with cornstarch, we’re removing some of the gluten and replacing it with a tenderizing element. But cornstarch is so neutral, how is it a cake tender? Well, cornstarch works alongside other cake ingredients (like sugar, for example) to inhibit gluten development. It’s ingredients like sugar and cornstarch that compete with the flour for liquid absorption (think: eggs and buttermilk) in a recipe. If flour gets to gobble up all of the liquid in a recipe and is worked in a mixer (like we work cake batter), it’s gluten development will be off the charts… and you’ll basically have a baguette. Cornstarch (and sugar) makes the flour share liquid, easing the gluten development and creative beautifully tender cake texture.
Regarding the alleged "toxicity" of corn starch: it's not toxic. It's not endowed with nutrients, but it's not poison. Corn starch is indeed present in lots of processed foods, and lots of processed foods are indeed unhealthy. An ingredient's presence in an unhealthy food does not by extension make that ingredient toxic. Eggs are on the ingredients list for Twinkies. Now, I don't think anyone here would suggest that eating cornstarch is like eating eggs (after all you wouldn't eat a plate of scrambled corn starch), but 1/4 cup of cornstarch in an entire cake is not going to give you cancer, gout, IBS, sunburn, headaches, arthritis, the flu, neurodegenerative diseases, obesity, osteoporosis, insulin resistance, diabetes, heart disease or acne.

Why the cornstarch? What does it do? Could I sub the same amount of potato starch? I try to avoid cornstarch.

Yes, I agree. I don't know why so me recipes on Food52 have cornstarch as an ingredient when it is so unnecessary and a harmful/toxic ingredient in general.

Every year for my boyfriend's birthday, I make Swedish Birthday Cake (Jordgubbstårta), which is basically angel food cake with strawberries and whipped cream. I think I might need to try this one this year. Looks amazing.

My mom's side of the family always chooses (and fights over) a cake very similar to this, only with lightly sweetened fresh whipped cream between layers. It's one of the few cakes that I will eat til I'm about to explode. This looks like another entirely dangerous version.
