Margarines for biscuits and dry cookies: controlling spread, crunch and snap
When people talk about biscuits and cookies, they usually focus on flavours, chocolate chips and packaging. Behind every good biscuit, however, stands the fat phase. In industrial production this role is most often taken by specialized biscuit or cookie margarines.
Unlike puff pastry margarines, which build layers, or cake margarines, which create a soft crumb, margarine in biscuits is responsible for spread during baking, internal structure, crunch and that characteristic snap when the biscuit breaks.
Why use margarine in biscuits and dry cookies
Industrial biscuit producers choose margarine because it provides a stable structure for both dough and finished product, allows controlled spread during baking, influences whether the biscuit will be crisp or soft, supports consistent quality and practical shelf life and offers more stable cost and properties than butter.
For brands and private label projects, margarine is a key tool for achieving the same shape and texture in every batch, which is essential in industrial manufacturing.
The role of margarine in biscuit structure
Spread on the baking tray
During baking, fat melts, the dough structure softens and the biscuit spreads in width before it sets. The profile of the margarine, its melting point and consistency, directly affects the biscuit diameter, how much it flows, its thickness, whether it becomes a thin, crisp disc or a thicker cookie style piece and how uniform the batch is.
If the margarine is too soft and low melting, the biscuit may spread too much and become overly thin. If it is too hard and high melting, the biscuit can remain dense, crack and feel heavy.
Crunch and snap
For classic dry biscuits, such as tea biscuits, petit beurre types and similar products, the target is a crisp structure, a clean snap when broken and a crumb that breaks finely without gumminess.
Here margarine, together with moisture and sugar content, determines how hard the biscuit is, how fast it loses or absorbs moisture and whether it stays crisp throughout its shelf life.
Softness in cookie style products
In soft baked cookies, often with chocolate chips or nuts, a chewy, softer structure is desired. In this case, margarine contains a higher proportion of softer, liquid fat fractions and the biscuit remains slightly flexible after baking.
Fat is part of the balance between crisp and soft, and the technologist chooses the margarine type according to the intended style of the product.
Types of margarine for biscuits and dry cookies
In practice there are specialized biscuit and cookie margarines with tailored fat structures.
Margarines for hard, crisp biscuits
These margarines are used for tea biscuits, petit beurre type products and biscuits intended for grinding, for example as bases for cakes and cheesecake.
They are characterized by a higher share of solid fat, a higher melting point than soft systems and the ability to produce thin, crisp biscuits with a clear break. Such margarines help the biscuit keep its shape, avoid a greasy feel to the touch and remain crisp during storage.
Margarines for softer biscuits and cookies
These are applied in cookies with chocolate chips, soft baked biscuits and products that should remain chewy.
They have a higher liquid fat fraction and a somewhat lower melting point. The result is a softer crumb, less pronounced snap and a fuller mouthfeel, together with a better ability to stay soft over several days.
All purpose margarines for mixed programmes
In plants with a broad product range, all purpose margarines are sometimes used. They can serve both for standard biscuits and for some cake applications and provide a compromise between crispness and softness.
They are practical for smaller producers who want to minimise the number of different raw materials, but for special or premium biscuits it is common to introduce a dedicated biscuit margarine to achieve precise texture and consistency.
Margarines in sandwich and filled biscuits
In sandwich biscuits, where two biscuit halves are joined with a filling, margarine appears both in the dough and in the cream. In such systems it is important to harmonise the texture of biscuit and filling.
The biscuit must not be so hard that it shatters on bite, nor so soft that it loses shape in the pack. The filling must remain stable, not separate or leak from the sandwich and bond well with the biscuit surface.
For this reason, manufacturers often choose compatible margarine systems. The same supplier may offer a margarine for the biscuit dough and a margarine for the filling, optimised to work together.
Process and margarine: what technologists need to watch
Temperature of margarine and dough
For biscuits it is critical that the margarine is at the correct temperature and that dough temperature is controlled.
If the margarine is too cold, mixing becomes difficult and the structure uneven. If it is too warm, spread increases and biscuits may deform in the oven. A stable temperature regime helps to reproduce spread and thickness from batch to batch.
Mixing method
Biscuits can be produced by different methods, such as classic creaming of margarine and sugar followed by adding other ingredients, or all in methods for specific formulations.
For products where structure is critical, biscuit margarines are optimised to behave predictably in the chosen process. The technologist should align process and margarine type with the supplier’s recommendations.
Baking and cooling
Biscuit margarines must help the product keep its shape during baking, without unwanted fat leakage, and allow the structure to set quickly during cooling. They should also avoid bending or warping on cooling racks and conveyor belts. A suitable fat system reduces waste and simplifies packaging.
How to choose margarine for biscuits: a practical approach
When selecting margarine for biscuits, technologists and buyers should start from the product type. There is a clear difference between hard tea biscuits, classic dry biscuits with cocoa or inclusions, sandwich biscuits and soft baked cookies. Each group requires a different fat profile and there is no single margarine that is optimal for all styles if high consistency is the target.
The next step is to define whether the primary goal is crispness, softness or something in between. If crispness is crucial, margarines with higher melting points and firmer structures are chosen. If the aim is a softer, chewy cookie, margarines with more liquid fat are preferred. For hybrid products compromise cookie margarines are used.
It is always useful to test spread and biscuit size with two or three margarine types. Measuring diameter and thickness after baking and assessing uniformity and appearance gives a clear picture. Sometimes one margarine will produce a noticeably larger diameter, which can affect the number of pieces per kilogram of dough and the packaging concept.
Finally, behaviour during shelf life must be checked. Samples should be stored under realistic conditions, in appropriate packaging and at room temperature. Crunch, aroma, taste and texture are then evaluated after seven, fourteen or thirty days, depending on the intended shelf life. A well formulated biscuit margarine will help the product stay within the desired sensory window for longer.
Conclusion
Margarines for biscuits and dry cookies are specially designed fat systems that determine spread during baking, crispness or softness, structure and snap, appearance and uniformity and product performance during storage.
For serious biscuit manufacturers, from large industrial plants to ambitious smaller bakeries, choosing the right margarine is not a minor detail but a central part of product development and a foundation for a stable brand in the biscuit category.
