Blueberry Cornmeal Upside Down Cake
Some recipes are winners, some recipes are complete duds, most are like this one - pretty okay. It’s an easy, straightforward recipe that yields a pretty tasty cake. Nothing special, nothing lifechanging.
I’m still sharing this recipe because I actually make it almost every summer. Inevitably, when overwhelmed with the abundance of in-season produce at the market, I impulse purchase way too much and have to deal with a fridge full of fruit I can’t eat. This is one of my go-to recipes, mostly because it’s so easy.
Like the Paula Wolfert chicken recipe, this one comes from the Food & Wine compilation book I bought the summer after college. It was there before any professionally collected recipes were added to my arsenal. And with every summer and every iteration, it just further cements its role as an essential summer staple.
I guess I just don’t want to overhype something that is, honestly, a little plain. One of the main reasons I make it every year is ….because I make it every year. But plain isn’t a bad thing. If the idea of a course-crumbed corn cake sounds good to you, you won’t be disappointed. You just might not be wowed either? And that’s okay!
Blueberry Cornmeal Upside-down Cake
For a 10-inch cast iron pan
Fruit Layer
In the bottom of the cast iron pan, melt together:
1/4 cup (1/2 stick) butter
115g brown sugar
Simmer mixture over low heat until sugar is dissolved completely, about 2-3 minutes. Stir constantly.
Remove from heat, then add:
3 cups blueberries
Spread the blueberries in one even layer as much as possible, and set aside.
Batter & Bake
Using a mixer, thoroughly cream together:
1 cup (2 sticks) butter
300g sugar
Add slowly:
4 eggs, room temperature
2 tsp vanilla
This is one of few cakes where not breaking the emulsion actually makes a difference in the final product. Allow your eggs to come to temp (shortcut: soak them in lukewarm water) and add it one by one, scraping well in between additions.
Add and mix together on low speed:
200g AP flour
3/4 cup yellow cornmeal
1 Tbsp baking powder
1 tsp salt
Lastly, fold in:
3/4 cup plain full-fat yogurt
Top the fruit layer with the batter, roughly spread it into an even layer, and bake at 350F until cooked through in the center, about 40-50 minutes.
Let the cake cool in the pan for about 10 minutes, then flip it onto a plate.
Unmold the cake while it’s still warm!
If you leave it and forget, you will need to pop it into a low oven again to rewarm the bottom
Serve with ice cream or (as I prefer) a dollop of unsweetened creme fraiche whipped cream.
Notes
Blueberry and corn are a classic combo, but the batter will also work with most summer fruits. In the past, I’ve also added orange zest since it’s my favorite thing to combine with blueberries. But the zest does change the profile and feel of the cake, and in peak summer I like it better without.
Confession: I have never made this in a cast iron. It would for sure get a better crust there, but it tastes great out of a stainless-steel skillet or a cake pan too.
Scaling: Do the math beforehand if you’re using a different pan! For a 12-inch skillet, you nees ~50% more batter and fruit. A 8-inch cake pan will have 1/3 the batter left over. Small change in diameter -> big difference in surface area and volume.
