papaya substitute
in cake.
Papaya folded into Cake batter adds natural sweetness and moisture that keeps the crumb tender. The substitute must match its water content and flavor.

adjustment for this dish
Cherimoya at 1:1 piece purees as smoothly as papaya and folds into creamed butter with no bleed, but its seeds must be picked out first — one stray black seed ruins a slice. Cherimoya's acidity is lower than papaya's, so reduce added baking powder back to the recipe's original amount rather than boosting it, and pull the cake at 30 minutes because the crumb sets faster.

Custard-Apple
10.0best for cake1 piece : 1 piece
Soft creamy tropical flesh
10.0
adjustment for this dish
Custard-apple at 1:1 piece delivers a pale puree with a creamy fat content closer to avocado than to papaya, so the crumb comes out noticeably richer. De-seed thoroughly, puree to 3 mm consistency, and fold into the creamed butter and sugar after 4 minutes on medium-high. Because custard-apple lacks papaya's acid, skip the baking powder boost and trust the formula's rise — the cake bakes fully at 35 minutes with a clean toothpick.

Persimmons
10.0best for cake1 piece : 1/2 piece
Soft sweet tropical alternative
10.0
adjustment for this dish
Persimmons sub 1:0.5 piece — half the volume of a papaya cup because persimmon solids outweigh papaya's water-heavy flesh. Use only fully ripe Hachiya (jelly-soft) or Fuyu puree; under-ripe persimmon carries tannins that react with butter fat and leave the crumb chalky. Fold the puree in after creaming, and bake 2 minutes longer — the denser fruit slows heat migration to the center.

Mango
10.01 cup : 1 cup
Closest tropical match in sweetness and texture
10.0
adjustment for this dish
Mango at 1:1 cup purees as brightly as papaya but with more fiber strands; push the puree through a fine sieve before folding in, or stray threads show up as streaks in the crumb. Mango's higher Brix (14 vs papaya's 11) means pulling sugar back by 1 tbsp per cup keeps the cake from over-browning at the edges.
05
Apricots
10.01 cup : 1 cup
Fresh apricots sliced; slightly more tart
10.0
adjustment for this dish
Apricots at 1:1 cup must be peeled and pitted, then pureed to the same 3 mm silk as papaya. Their tartness (pH 3.5 vs papaya's 5.5) actually boosts baking soda rise, so cut the added leavener by 1/8 tsp per cup to keep the crumb from over-puffing and collapsing mid-cool.

technique
Papaya puree folded into cake batter behaves like a flavored buttermilk: it softens the crumb through moisture and acid, but it also buffers baking soda so rise flattens unless you adjust. Puree only ripe flesh to 3 mm consistency, strain through a fine sieve to lose 20% of its free water, then whisk it into the wet side after creaming butter and sugar for 4 minutes on medium-high.
Sift the flour with an extra 1/4 tsp baking powder per cup to compensate for the papaya's pH drag, and fold (never beat) to keep gluten tender. Unlike papaya in cookies, where chunks are the whole point, cake demands total disappearance of the fruit into the batter so the crumb stays even and the toothpick comes out clean at 32 minutes.
Pan-line with parchment — papaya-heavy batters stick harder than plain cake — and cool 15 minutes in the pan before releasing, or the tender crumb tears at the edges.
