Digestive Biscuits substitute

Best substitute

Graham crackers

Use the same amount by weight (250 g digestives = about 16 to 18 full graham sheets) as the digestive biscuits you are replacing

Best for cheesecake bases

Close match

Graham crackers are the swap, and they work one for one by weight, which is how you should measure this rather than counting biscuits. A 250 g packet of digestives is roughly 16 to 18 full graham cracker sheets, or about 2 cups of crumbs. Grahams are a little sweeter and honey-ish, so cut any added sugar in your base recipe by half. Rich tea, Marie or arrowroot biscuits also work one for one by weight and are available almost everywhere, though they are plainer, so add a pinch of salt and a teaspoon of brown sugar per 200 g of crumbs. In a cheesecake base a digestive is doing three jobs: providing dry structure, soaking up melted butter so the crust sets firm, and contributing a malty, slightly salty edge that keeps a sweet filling from being sickly. Any hard, dry, low-to-medium-sugar biscuit can do the first two. The third is what you have to think about.

Substitutes for Digestive Biscuits with ratios

  1. 2Rich tea, Marie or Maria biscuits, or arrowroot biscuits

    Different taste

    Use the same amount by weight

    Plain, hard, low-sugar tea biscuits sold under different names in almost every country.

    What changes
    Best for
    cheesecake bases, chilled tarts, fridge cake, when nothing else is available

    They crumb beautifully and set exactly as firmly as a digestive, so mechanically this is a great swap. The gap is flavour: they are pale, plain and made with white flour, so there is none of the wholemeal malt or the salt, and the base tastes distinctly blander and slightly cardboardy under a rich filling. Fix it with a pinch of flaky salt and 1 teaspoon of brown sugar per 200 g of crumbs, which is a small change that makes a big difference.

  2. 3Hobnobs, oat biscuits or oaty digestive-style cookies

    Taste and texture differ

    Use the same amount by weight, minus 1 tbsp of the melted butter

    Rolled-oat biscuits with more fat and more sugar than a plain digestive.

    What changes
    Best for
    lemon and chocolate cheesecakes, banoffee, millionaire's shortbread bases, rustic tarts

    Arguably better tasting than a digestive base, with a toasty oat flavour that suits lemon and dark chocolate especially well. They carry more fat already, so pull back a tablespoon of melted butter or the base turns greasy. Oats do not grind to a fine crumb, so the base is knobbly and coarse, which means it looks rustic and it does not slice as cleanly. Press it harder into the tin than you think you need to.

  3. 4Speculoos, Biscoff, gingernuts or ginger biscuits

    Different taste

    Use the same amount by weight, and omit any added sugar entirely

    Hard, dry, heavily spiced biscuits that crumb exceptionally well.

    What changes
    Best for
    pumpkin cheesecake, banoffee, lemon and lime tarts, chocolate and coffee bases

    Technically excellent because they are very dry and grind to a fine even crumb, and the base sets rock solid. The catch is that they are much sweeter and loudly spiced, so the base tastes of cinnamon or ginger. Under pumpkin, banoffee or a sharp citrus filling that is a genuine upgrade. Under a delicate baked vanilla cheesecake it is simply the wrong flavour and it will dominate. Skip all added sugar.

  4. 5Shortbread or Nice biscuits

    Taste and texture differ

    Use the same amount by weight, minus 2 to 3 tbsp of the melted butter

    Very buttery biscuits that already contain most of the fat a base needs.

    What changes
    Best for
    rich chocolate tarts, cheesecakes you will slice with a hot knife, small tartlets

    Delicious and very rich, and the main practical problem is fat. Shortbread is roughly a third butter by weight, so adding a full quantity of melted butter gives you a greasy base that chills into a hard toffee-like slab you cannot cut cleanly. Drop the butter by a third. Dip your knife in hot water to slice. Nice biscuits are the coconut version and behave the same way with a distinct coconut note.

  5. 6Wholemeal crackers or Weetabix, improvised

    Different texture

    200 g crushed crackers or 6 Weetabix + 2 tbsp brown sugar + a good pinch of salt

    The honest cupboard-scraping option when there is no biscuit of any kind in the house.

    What changes
    Best for
    a base you need tonight, no-bake cheesecakes, crumble toppings

    This genuinely works, and the wholemeal flavour is actually closer to a real digestive than a plain white tea biscuit is. What it lacks is sugar and fat, which you add back, and structural integrity: cracker and cereal crumb is drier and more fragile than biscuit crumb, so the base is more crumbly and needs an extra half hour in the fridge before it will hold a slice. Bake it for 10 minutes before filling and it improves a lot.

What is Digestive Biscuits?

Digestive Biscuits is Digestive biscuits, or digestives, are semi-sweet British wheatmeal biscuits made from wholemeal flour, a little brown sugar and baking soda, faintly malty and noticeably salty, sold most famously as McVitie's digestives and used crushed as the base for cheesecakes.

Cooking tips

  • The working ratio for any biscuit base is roughly 2 parts crumbs to 1 part melted butter by weight: 250 g crumbs to 100 to 125 g butter. When you switch to a sweeter, oatier or more buttery biscuit, adjust the butter down rather than fiddling with anything else. Too much butter is the single most common reason a base turns greasy or rock hard.
  • Weigh, do not count. Digestive biscuits vary a lot in diameter and thickness between brands and countries, so substituting biscuit for biscuit by number regularly leaves you 20 percent short of crumb. For reference, 250 g of digestives is about 15 to 16 biscuits and gives roughly 2 cups of crumbs.
  • Bake the base for 10 minutes at 180C / 350F before filling, even for a no-bake cheesecake. It drives off moisture, firms the crumb and makes any substitute biscuit behave far more like a digestive. Cool it completely before the filling goes in.
  • Digestive biscuits contain no digestive enzymes and do nothing for your digestion. The name comes from the sodium bicarbonate in the dough, which Victorian bakers believed was an antacid. It is a wholemeal biscuit with a marketing history.
  • If you are eating them rather than baking with them, remember digestives are salty-sweet and designed for cheese and strong tea, not for dessert. A wheatmeal cracker or a plain oatcake is a much better plain-eating substitute than any sweet cookie.

Frequently asked questions

Can I use graham crackers instead of digestive biscuits?

Yes, and it is the best swap available. Use the same weight, not the same number: 250 g of digestives is about 16 to 18 full graham cracker sheets. Grahams are sweeter and have a honey note, so halve any sugar the base recipe adds. Everything else about the method stays the same, including the butter quantity and the 10-minute pre-bake.

How many digestive biscuits are in a cup of crumbs?

Roughly 8 digestives give 1 cup of fine crumbs, so a standard 250 g packet gives about 2 cups. Most cheesecake bases for a 9-inch tin want 200 to 250 g of biscuits with 100 to 125 g of melted butter. Because brands differ, weigh the biscuits if you can and treat cup measures as a guide.

Can I leave the biscuit base out altogether?

You can make a crustless cheesecake, and it is a real recipe rather than a compromise: bake it in a well-buttered lined tin at a lower temperature, around 160C / 320F, and chill it thoroughly before unmoulding. But you are not substituting anything, you are baking a different dessert. In a base, the biscuit is doing structural work, giving you something firm to slice against and a dry layer that stops the filling wetting the tin, and nothing replaces that except another crumb.

Are digestive biscuits sweet?

Only mildly, which is exactly why they work in a base. They contain far less sugar than most cookies and a noticeable amount of salt, so they taste more like a savoury cracker than a dessert biscuit. That balance is what keeps a sweet cheesecake filling from tasting sickly, and it is the thing you lose if you substitute a sweet spiced cookie without cutting the sugar elsewhere.

Can I make a biscuit base without butter?

Not really, because the fat is the glue. Melted butter coats the crumbs and sets solid when chilled, which is the only thing holding the base together. Coconut oil works one for one and sets even firmer. A neutral oil sets much softer and gives a base that crumbles when sliced. Water or milk does not work at all, it just makes wet crumbs that never firm up.
