Most low-calorie baking fails because it fixes the recipe instead of the ingredients. Banana bread is roughly 3 calories per gram no matter what you swap into it, so a lighter version is still one small slice you want three of.
The number that decides everything is energy density. Under 1 calorie per gram, portion size stops mattering. These two clear that bar, and one of them is mostly protein.
A set custard, not New York cheesecake. Tangy and light rather than rich, because there is no cream cheese and almost no fat.
| Ingredient | Weight | Volume |
|---|---|---|
| 0% Greek yogurt | 500 g | 2¼ cups, or one 17.6 oz tub |
| Large eggs | — | 2 |
| Allulose | 40 g | 3 tbsp |
| Cornstarch | 15 g | 2 tbsp |
| Vanilla | — | 1 tsp |
| Lemon zest | — | 1 lemon |
| Salt | — | ¼ tsp |
The yogurt is 70% of the mass and the only measurement worth being precise about. Everything else has slack. Allulose is 70% as sweet as sugar, so go to 4 tbsp if 3 tastes flat.
Do not eat it warm. It is soft and disappointing out of the oven and a completely different food after a night in the fridge. Judging it before it is cold is the mistake almost everyone makes.
Keeps five days. Double it in a 9-inch pan to last a week.
380 cal, 53g protein, about 505g baked. The density barely moves: 75 cal per 100g, and a quarter is 95 cal.
| Ingredient | Weight | Volume |
|---|---|---|
| 0% Greek yogurt | 400 g | 1¾ cups |
| Large eggs | — | 2, do not scale down |
| Allulose | 32 g | 2½ tbsp |
| Cornstarch | 12 g | 1½ tbsp |
| Vanilla | — | 1 tsp |
| Lemon zest | — | 1 lemon |
| Salt | — | ¼ tsp |
Keeping both eggs is deliberate. It raises the egg-to-yogurt ratio about 25%, which is what you want at a smaller volume and doubly so if the starch is light or missing. A single tablespoon of cornstarch is enough here for the same reason.
Use a 6-inch springform or a small loaf pan, since a 7-inch makes it thin and it overbakes. Start checking at 35 minutes rather than 45, at the same 300°F.
The topping for the cheesecake, and a dessert on its own. Roasting concentrates them into something jammy and far more intense than raw fruit.
Halve and pit the plums, lay them cut side up on parchment, scatter over allulose and a pinch of cinnamon or a splash of vanilla. Roast at 400°F for 20 to 25 minutes. That is the entire recipe.
Cornstarch is not structural here. The eggs set the cake; the starch binds free water so it does not weep after a day or two, widens the margin before the yogurt curdles, and makes it sliceable rather than spoonable. It costs 55 calories for the whole pan.
Potato starch, tapioca and arrowroot all substitute 1:1 for the cornstarch.
| Symptom | Cause |
|---|---|
| Grainy or curdled | Oven too hot. Drop it 25°F. Yogurt breaks above about 315°F. |
| Watery, weeping | Did not strain, skipped the starch, or overbaked. |
| Cracked top | Too hot, air whipped in, or cooled too fast. |
| Rubbery | Overbaked. |
| Bland | Under-salted. With no fat to carry flavor, salt and acid do all the work. The zest is not optional. |
Skip protein powder. Whey pushes the pan to about 88g of protein but turns it rubbery and dry. Casein blends in without the penalty if you already have some.
For a 6-inch pan: 35g rolled oats, 20g walnuts pulsed coarse, 1 egg white, 1 tbsp allulose, a pinch of salt. No butter. Press it in and bake at 350°F for 10 to 12 minutes until it smells toasty.
The walnuts replace the butter, not the oats. Same calories as a butter-bound crust, better flavor, and the nut fat waterproofs the crust from the inside. Pulse them coarse so they stay texture rather than paste.
Two steps carry the whole thing:
The cost is real, and it breaks the premise the rest of this page is built on. Per slice assumes quartering the small pan, whose base is 380 cal at 75 cal per 100g.
| Crust | Total | Per slice | Density |
|---|---|---|---|
| None | 0 | 0 | 75 |
| High-fiber cereal + egg white | ~170 | 42 | ~98 |
| Toasted oat, no fat | ~212 | 53 | ~105 |
| Oat + walnut | ~286 | 72 | ~116 |
| Oat + butter | ~284 | 71 | ~116 |
| All walnut | ~409 | 102 | ~128 |
| Graham cracker + butter | ~515 | 129 | ~148 |
On walnuts. At 654 cal per 100g they are the most expensive thing that goes in a crust, and an all-walnut version nearly matches graham cracker, which defeats the point. But they are the best ingredient per gram on the things that matter: they toast hard, stay crunchy, and their fat seals the crust from the inside. At 20g they are a flavor and texture ingredient rather than the bulk.
Cheapest crust that still reads as a crust: high-fiber cereal, about 170 calories. Fiber One and similar run roughly 200 cal per 100g because most of the weight is fiber. Crush it and bind with an egg white.
Consider a topping instead. Bake the same mixture loose on a sheet pan as a crumble and scatter it on right before eating. Identical crunch, no sogginess risk, and you control the portion per slice instead of committing it across the whole pan. It keeps separately in a jar for weeks.
Allulose is a rare sugar, about 0.4 calories per gram against sugar's 4. Your body absorbs it but cannot metabolize it, so it leaves mostly unchanged. It is not artificial and not a sugar alcohol. The "0 calories" on the bag is a labeling rule, not literal: anything under 5 calories per serving rounds to zero.
The reason to use it specifically: it browns and caramelizes. Stevia and erythritol do not. That is the whole reason roasted fruit and baked custards work with it and taste like dessert instead of like diet food.
Safety looks solid and there are modest positive signals on post-meal glucose, but widespread use is only about a decade old and long-term data is thin. It is not a health food. It is a nearly free replacement for something that is actively bad.
| Dessert | Density | Note |
|---|---|---|
| Angel food cake | 70–95 cal/slice | The only real cake that is mostly air, and it has no fat at all. Egg whites, cream of tartar, cake flour, sugar half-swapped for allulose. |
| Pavlova | ~20 cal each | Four egg whites is 68 calories total and bakes into an enormous amount of food. Use real sugar here. |
| Crustless pumpkin custard | ~50 cal/100g | Canned pumpkin is 26 cal per 100g. Pumpkin, eggs, sweetener and pie spice, baked in ramekins. |
| Baked apples | ~95 cal each | Core, cinnamon, vanilla, 375°F for 30 minutes. Effectively unlimited. |
