Winter Citrus Upside-Down Cake

Winter Citrus Upside-Down Cake. Orange and grapefruit rounds over a tender olive-oil cornmeal cake, inverted while warm. The formula and timing below are working estimates for a future kitchen trial, not a claim that a batch has been made.

A citrus mosaic over cornmeal

Orange and pink grapefruit circles form the top after inversion. A fine-cornmeal olive-oil batter makes this a different cake from a buttery caramel-apple version, but the calendar has several upside-down cakes close together.

Treat it as a separate URL only after a final intent review; the precise pith removal, moisture and release need kitchen testing.

Keep the fruit thin and clean

Cut away peel and white pith before slicing crosswise. Remove grapefruit seeds and arrange thin circles in one layer so the batter has room to set.

Too much pith can taste bitter; grapefruit varieties vary. Note the exact fruit size and bitterness in the first test rather than promising a reliably sweet topping.

Ingredients for 8 slices

Step-by-step method

1. Heat oven to 350°F. Line the bottom of a solid-bottom 9-inch cake pan with parchment, spread 3 tbsp melted butter and scatter 1/3 cup packed brown sugar evenly. Remove peel and white pith from one orange and one grapefruit, then slice into thin crosswise circles, remove seeds and arrange a single overlapping layer over sugar.
2. Whisk 1 cup flour, 1/2 cup fine cornmeal, 1 1/2 tsp baking powder and 1/2 tsp salt. Separately whisk 3/4 cup sugar, two eggs, 1/2 cup olive oil, 1/2 cup plain yogurt and 1 tsp orange zest. Fold dry into wet until just combined.
3. Spread batter gently over citrus. Bake approximately 45–50 minutes until the cake portion passes a skewer test without wet batter; fruit syrup on the skewer is not raw cake. Rest in pan about fifteen minutes.
4. Loosen sides, invert onto a serving plate while still warm and remove pan and parchment carefully. Cool roughly forty-five minutes more, then cut eight provisional slices. Verify citrus bitterness, topping release, moisture and timing in a kitchen trial.

Cornmeal in a cake batter

Use fine yellow cornmeal, not coarse polenta, alongside all-purpose flour. Whisk olive oil, eggs, yogurt, sugar and zest, then fold in dry ingredients only until combined.

The batter should cover citrus without shifting the pattern. A solid-bottom pan avoids losing buttery sugar through a springform seam.

Invert while warm

Bake until a skewer checks the cake portion, not the syrupy fruit layer. After a fifteen-minute pan rest, loosen the edge and invert carefully onto a plate.

Stephanie's Dish gives a winter-citrus cake reference. It does not validate this separately proposed olive-oil and cornmeal ratio or its eight portions.

Serving and overlap review

Cool further before slicing. A lightly sweet cake can be served alone; cream is an optional separate pairing, not a measured ingredient.

The pear and apple upside-down drafts use other fruits and batters, but the shared format may dilute search intent. Review which merits a distinct page and whether another should become a variation.

Citrus cake questions

Do the citrus peels stay on?

No. Peel and white pith are removed before slicing.

Can I use coarse polenta?

Not as a direct swap; the working batter specifies fine cornmeal.

Why is there no caramel sauce?

Butter and brown sugar are underneath the fruit in the pan and become the topping when inverted.
