If your scones don’t end up rising then don’t fret as that is a common issue with first-timers. There are three main reasons why it could be happening. First and most likely you have simply over kneaded the dough in step 5. Just make sure to knead it until it forms a rough dough and no more. The second possible reason is that you aren’t cutting out the scones properly. Always make sure to cut down and up, never twist as that can cause the sides to seal resulting in them being unable to rise. If you’ve done both of those properly then the only other reason your scones aren’t rising is that your baking powder is too old.
