In the United States, a flapjack is a thick pancake served with maple syrup (and sometimes fruit), but in the United Kingdom, flapjacks are something else entirely, and they're nothing like pancakes as Americans know them. (The British don't really eat pancakes per se; the closest food item would be a French crêpe).

This flapjack is what the British would call a tray bake (similar to a bar cookie). But it's not a biscuit or a cookie in either region's baking vernacular—think of it more like a homemade granola bar, packed with whole-grain oats and sweetened with golden syrup.

It's easy to make a great British flapjack in 35 minutes. This traditional favorite is equally at home on the tea table or in a lunch box or picnic basket. The snack is inexpensive, delicious to eat, and easy to customize using your own preferences, even if that includes chocolate and toffee, or ginger root.

Ingredients

  • 6 tablespoons golden syrup (or light corn syrup)
  • 6 ounces/200 grams unsalted butter (plus 1 teaspoon for greasing the pan)
  • 4 cups/330 grams porridge oats (rolled oats)
  • 1 pinch salt
  • Optional: 1 pinch ground ginger

Steps to Make It

  1. Gather the ingredients.

  2. Heat the oven to 350 F/180 C/Gas Mark 4.

  3. Use 1 teaspoon butter to grease a 9 x 9-inch or 9 x 13-inch baking pan and line the base with parchment paper. The smaller pan will yield thicker and chewier bars; the larger pan's flapjacks will be crispier and thinner.

  4. Place the golden syrup and 6 ounces of butter into a large saucepan and heat gently, stirring well, until the butter has melted into the syrup.

  5. Put the oats in a large bowl and add a pinch of salt and the optional ginger. Pour in the butter and syrup mixture and stir to coat the oats.

  7. Bake in the heated oven for about 25 minutes or until golden brown. Remove from the oven while the flapjack is still slightly soft; it will harden once it has cooled.

Recipe Variations

This recipe is for a traditional flapjack, but there are also many variations. The method for these alternative flapjack recipes is the same as above; just vary the quantities and ingredients as follows.

  • Coconut Flapjack: Use the same amount of oats and add in 2 ounces/55 grams of sweetened dried coconut and continue with the recipe.
  • Apricot and Honey Flapjack: This healthier version of a flapjack is made by melting 3 1/2 ounces (100 grams) butter with 3 ounces (85 grams) soft brown sugar and 3 tablespoons honey, and then mixing with 12 ounces (350 grams) oats mixed with 3 1/2 ounces (100 grams) finely chopped dried apricots and 1 small mashed ripe banana.
  • Nuts and Seeds Flapjack: Add 2 tablespoons chopped mixed nuts and 2 tablespoons mixed seeds such as pumpkin and sunflower to the oats mixture.
