These oatcakes are a traditional Scottish-style flatbread made simply from oats, water, and a little fat—here, butter or a neutral oil stands in for palm oil, which is often used in commercial versions. They come out crisp, nutty, and sturdy enough to top with cheese or jam, yet they come together in one bowl with no special equipment. This recipe uses a small amount of butter for flavor and structure, but you can easily swap in a plant-based oil for a dairy-free version.
Ingredients
- 2 cups (200 g) rolled oats (not instant)
- 1/2 cup (60 g) oat flour (or finely ground rolled oats)
- 1/2 teaspoon fine sea salt
- 1/4 cup (55 g) unsalted butter, melted, or 1/4 cup (60 ml) neutral oil (e.g., sunflower or canola)
- 1/2 cup (120 ml) hot water, plus 1–2 tablespoons more if needed
- Extra oat flour for rolling
Instructions
- Preheat the oven to 350°F (175°C). Line a large baking sheet with parchment paper.
- In a food processor, pulse the rolled oats for about 30 seconds until they resemble coarse flour. You want some texture left, not a fine powder. Transfer to a mixing bowl.
- Add the oat flour, salt, and melted butter (or oil) to the bowl. Stir with a fork to combine.
- Pour in the hot water and stir until a dough forms. It should be moist but not sticky. If it seems dry and crumbly, add another tablespoon of hot water. Let the dough rest for 5 minutes—this lets the oats absorb the liquid.
- Turn the dough onto a surface lightly dusted with oat flour. Knead gently 2–3 times until it comes together. Roll it out to about 1/8-inch (3 mm) thick. If the dough cracks at the edges, that’s normal; just patch it with your fingers.
- Cut into rounds with a 2-inch (5 cm) cutter, or use a knife to make squares or triangles. Re-roll the scraps and cut again.
- Place the oatcakes on the prepared baking sheet, leaving a little space between them. Prick each one with a fork to prevent bubbling.
- Bake for 20–25 minutes, until the edges are lightly golden and the oatcakes feel dry and firm. They will crisp up more as they cool.
- Transfer to a wire rack and cool completely. They will harden as they cool.
Tips
- Use the right oats: Rolled oats give the best texture. Quick oats will make a softer, more powdery oatcake. If you only have quick oats, reduce the water by 1–2 tablespoons.
- Don’t overwork the dough: Over-kneading makes the oatcakes tough. Mix just until combined, and handle the dough as little as possible when rolling.
- Adjust thickness for crunch: Thicker oatcakes (about 1/4 inch / 6 mm) will be chewier; thinner ones (1/8 inch / 3 mm) will be crisp. For a classic crisp oatcake, roll thin.
- If using oil instead of butter: Use a mild oil like sunflower or canola. Olive oil will add a distinct flavor that may not suit sweet toppings.
Serving Suggestions
Serve these oatcakes as a base for savory toppings: a slice of sharp cheddar and a dollop of chutney, smoked salmon with a little crème fraîche, or simply with butter and honey. They also work well alongside soups and stews in place of bread. For a sweet treat, spread with jam or lemon curd.
Variations
- Seeded oatcakes: Add 2 tablespoons of mixed seeds (sunflower, pumpkin, sesame) to the dry ingredients before adding the water.
- Herb oatcakes: Stir in 1 teaspoon of dried thyme, rosemary, or oregano along with the salt.
- Whole-wheat blend: Replace half the oat flour with whole-wheat flour for a slightly heartier texture.
- Sweet version: Add 1 tablespoon of sugar or honey to the dry ingredients and reduce the salt to 1/4 teaspoon. Serve with fruit and cream.
Storage and Reheating
Store the cooled oatcakes in an airtight container at room temperature for up to 5 days. They will lose some crispness over time; to refresh, place them on a baking sheet in a 300°F (150°C) oven for 5 minutes. You can also freeze them for up to 3 months—stack with parchment paper between layers in a freezer bag. Thaw at room temperature and re-crisp in the oven as above.
Frequently Asked Questions
Can I use steel-cut oats instead of rolled oats? No, steel-cut oats are too hard and won’t break down enough to form a dough. Stick with rolled oats or quick oats.
Why are my oatcakes falling apart? The dough may be too dry. Add a little more hot water, a tablespoon at a time, until it holds together when pressed. Also, make sure to let the dough rest for 5 minutes so the oats can hydrate.
Can I make these without a food processor? Yes. You can use a blender to grind the oats, or buy oat flour and mix it with the rolled oats. If you don’t grind them at all, the oatcakes will be very rustic and may break more easily.
Are these gluten-free? They can be, if you use certified gluten-free oats and oat flour. Regular oats are often cross-contaminated with wheat, so check the label if you need strict gluten-free.
Can I cook these on the stovetop instead of baking? Yes, you can cook them on a dry griddle or heavy skillet over medium-low heat for about 3–4 minutes per side, until browned and crisp. They will be slightly softer than baked ones.
What is the best way to roll them out? Use a rolling pin on a surface dusted with oat flour. If the dough sticks, dust the top of the dough with a little more oat flour. Rolling between two sheets of parchment paper also works well.
