Most of the bake-sale table sits at the safe end of the oxalate scale: the cookies, the cakes, the brownies, and the cupcakes all measure in the single digits per serving. The items that carry the oxalate check are the specific few: anything made with dark chocolate, and the nut-heavy bakes like almond biscotti or pecan bars. The measured version of the table is not to skip the sale — it is to know which column each item sits in, and to portion accordingly. The occasional cookie is not a stone problem; the daily sweet habit is.
The table below shows the measured oxalate values of the common bake-sale items.
| Food | Oxalate (mg) | Serving | Rating |
|---|---|---|---|
| Sugar cookie | 2 | 1 cookie | Safe |
| Chocolate chip cookie | 5 | 1 cookie | Safe |
| Brownie | 21 | 1 brownie | Safe |
| Vanilla cupcake | 7 | 1 cupcake | Safe |
| Cake, white or yellow | 7 | 1 slice | Safe |
| Dark chocolate, bar | 65 | 1 oz | Caution |
| Chocolate brownie (dark) | 50+ | 1 brownie | Caution |
| Almond biscotti | 50+ | 1 piece | Caution |
| Pecan bar | 50+ | 1 bar | Caution |
| Sugar cookies (plain) | 2 | 1 cookie | Safe |
| Fruit cup | 1 | 1 cup | Safe |
| Water | 0 | 1 cup | Safe |
The oxalate column on the treat table is short, but the sugar column is the one worth watching. The sweet items are fine as the occasional treat, and the cohort data on sugary drinks — not baked goods — is where the daily-habit warning lives. The measured version of the bake sale is the same as the dessert-at-dinner rule: one sweet item, portioned, with water alongside. The family that treats the bake sale as an occasional event rather than a daily stop has already run the plan correctly; the sweets themselves are not the problem, the daily habit is.
The measured bake sale is a participation, not an opt-out: choose the low-oxalate item, take the one portion, and keep the water bottle at the table. The child or parent with a stone history does not need to skip the fundraiser — they need the portion and the water. The treat table is the plan's easiest environment, because the oxalate column is almost entirely safe and the rule is the one the plan already uses everywhere: the occasional item, measured, with the water alongside.
Mostly yes — cookies, cakes, brownies, and cupcakes measure low oxalate. The items to portion are the dark-chocolate and nut-heavy bakes, which carry the oxalate check. The occasional treat is not a stone problem; the daily sweet habit is.
The specific few: dark chocolate bars and dark-chocolate brownies (50+ mg), almond biscotti, and pecan bars. The plain cookies, cakes, and cupcakes measure in the single digits per serving.
No — take part and portion: one low-oxalate item, with water alongside. The measured version is participation with a portion, not an opt-out.
