For cake or tart batter, choose plain porridge oats with a simple ingredients list if you want to decide which sweeteners to add to the recipe yourself. Fine oats are a practical choice when the recipe calls for them, but the sugar content of the bake also depends on the other ingredients. If your bake needs to be gluten-free, choose oats explicitly labelled gluten-free and check the whole recipe.
If you want to control how sweet your cake or tart is by choosing your own recipe, a simple oat base is a sensible place to start. Consider fruit, dairy, sweeteners and toppings too: they all affect the final result.
When oats are mixed directly into a batter, the size of the flakes can affect how easily everything combines. Follow a recipe designed for porridge oats or oat flour rather than simply swapping out the plain flour in a recipe.
If you need to avoid gluten, the word ‘oats’ on its own is not enough. The Netherlands Nutrition Centre specifies gluten-free oats for its gluten-free oat cake recipe; you should also check the other ingredients.
Start with the requirement that matters most for your cake or tart recipe. Then compare the ingredients and nutritional information for the dry oats with the other ingredients you plan to add to the batter.
| What to consider | What should you check? | Who is this most important for? |
|---|---|---|
| Added sugar | Read the ingredients list and compare the sugars per 100 g of dry oats. Remember to include the other ingredients in your cake recipe too. | If I want to decide how sweet the batter will be, I don’t want to add sweeteners from the oat base. Around 46% of consumers give this the highest priority. |
| Oat texture | Check whether the recipe calls for fine oats or oat flour, and whether the packaging specifies that type. | For a batter where the oats are mixed in directly, I want a form that suits the recipe. This is the top priority for around 36% of consumers. |
| Gluten and allergens | If you need a gluten-free option, check for an explicit gluten-free label and read the allergen information on the current packaging. | If I have to avoid certain grains, the specific product packaging must meet that requirement. This is the first purchasing priority for around 18% of consumers. |
This claim on porridge oats does not describe the whole bake. Fruit, dates, milk, icing and other ingredients can also contribute sugars.
Consider the whole recipe and the portion size if you want to estimate the sugar content of the cake.

If you need a gluten-free option, look for an explicit gluten-free label and check the cake’s other ingredients too.
Ingredients, nutritional values and allergen information can change. If you have a strict requirement around sugar or allergens, the label on the packaging you use is what matters.
Before baking, read the current ingredients list, nutritional information and allergen declaration.

No. That claim applies to the oats, not the whole cake. Oats and ingredients such as fruit, dates, milk or icing can contribute sugars, so consider the full recipe and portion size.
Choose the type of oats specified in the recipe. Fine flakes are practical when you want to mix the oats straight into a smoother batter. It’s best to use a recipe developed for porridge oats or oat flour, as there’s no general flour substitution ratio that works for every cake.
