FAQs
Why did my oatmeal biscuits spread too much while baking?
Oatmeal biscuits spread too much if the butter is too soft or warm. Using properly softened butter and chilling the dough for 10–15 minutes before baking helps the biscuits hold their shape.
How do I make oatmeal biscuits crisp rather than soft?
For crisper biscuits, bake them a little longer until the edges are deeper golden and allow them to cool completely on a wire rack, where they firm up as they cool.
Can I use jumbo oats instead of regular oats?
Yes, jumbo oats can be used and will give a chunkier texture. Keep the same quantity, but expect a slightly more rustic bite.
How do I know when oatmeal biscuits are baked properly?
The biscuits are ready when the edges are lightly golden and the centres still feel slightly soft. They continue to set as they cool, so avoid overbaking.
Wrapping It Up
Mary Berry Oatmeal Biscuits are the kind of bake that feels familiar in the best way. They rely on simple ingredients, careful timing, and gentle handling to deliver biscuits that are crisp, comforting, and easy to enjoy. Keep a tin on hand, and they rarely last long.
