Not too bad but not as crumbly as the other. I guessed it's cos of the yogurt added.
@ the recipe was shared and posted by Doris Mok earlier. 
  I replaced heavy cream with yogurt instead.
 
Here goes the recipe :

• 500g flour, 1tbsp baking powder, 80g sugar, 1/2 tsp salt
• 180g unsalted butter
• 300g combine 1egg and heavy cream

1. Combine all A ingredients in a dry mixing bowl and add B to the flour. 
2. Rub the butter and flour till like bread crumbs. 
3. Mixed C to the crumbs and roughly mix till a dough. 
4. DO NOT OVERMIX. 
5. Turn the dough onto a floured top and flatten it till 1"thick. 
6. Cut it with cutter and bake for 15 to 20mins..at 170..
