Crunchy oat biscuits in a stack on a cooling rack.

Crunchy Oat Biscuits (Homemade Hobnobs)

Crunchy oat biscuits are my take on a classic favourite - think homemade Hobnobs with a perfectly crisp bite. They're really are so easy to make - no fancy equipment needed, just one bowl and a spatula.

Equipment

  • 2 large baking sheets lined with baking parchment or silicone mats

Ingredients

  • 150 g softened butter
  • 110 g caster sugar
  • 50 g golden syrup about 2 tablespoons
  • 210 g jumbo oats old fashioned rolled oats
  • 110 g plain flour
  • ½ tsp baking powder

Instructions

  • Preheat oven to 190°C (170°C fan)/ 375°F (325 °F fan)
  • In a mixing bowl, cream together the softened butter and caster sugar.
  • Cream in the golden syrup to mix well.
  • Add half the jumbo oats, half the plain flour and the baking powder. Mix well to combine.
  • Add the remaining oats and plain flour and stir again until your mixture comes together in a big ball.
  • Divide into 18 equal size balls and place onto the baking trays leaving a fair bit of space between each one.
  • Flatten the biscuit dough balls with your hand or a biscuit press (I use a burger press).
  • Bake for about 12 - 15 minutes or until the edges start to turn golden brown.
  • Leave the biscuits on the trays for 5 minutes before moving them to a wire rack. This helps them firm up without breaking.
  • Store in an airtight container once completely cool.

Notes

  • Oats - Jumbo oats give these biscuits their chunky texture and proper crunch. Avoid quick or instant oats, as they produce a softer biscuit. Baking tips
  • Bring the butter to room temperature ahead of time.
  • I use a hand held burger press to evenly flatten the biscuits for extra crunch.
  • If your biscuits spread too much, chill the dough for 15 minutes before baking.
  • Don't over bake your biscuits, they will crisp up as they cool. If they are too soft after cooling, you can always pop them back in the oven for 5 minutes.
  • Use two baking trays and don't overcrowd the tray as they spread slightly during baking. You may need to turn the trays during cooking to ensure an even bake. Variations
  • Chocolate Hobnobs - once cooled dip half of each biscuit in melted chocolate and allow to set.
  • Raisin and oat biscuits - add 2 tablespoons of raisins or sultanas with your flour and jumbo oats.
  • Ginger Oat biscuits - add a couple of tablespoons of chopped stem ginger with your flour and jumbo oats.
  • Dairy Free Option - use a plant based butter alternative. Storage
  • Store in an airtight container at room temperature for up to 5 days.
  • Freeze baked biscuits for up to 3 months.
