Step 1

Preheat the oven to 350°F.

Step 2

If desired, intensify oat flavor by toasting oatmeal on a cookie sheet, just until you can begin to smell it. Remove from oven and cool.

Step 3

Meanwhile, whisk together flour, sugar, baking soda, and salt. Cut in butter until it resembles fine crumbs.

Step 4

Add oats, then stir in the yogurt until a soft dough forms. You may need to add a tablespoon or so of milk, just enough to bring the dough together. The dough may be a little crumbly.

Step 5

Knead for about 30 seconds, pat into a ball, and with your hands, flatten into a round on a cookie sheet. The thinner your dough, the crisper the end result.

Step 6

Cut into 16 wedges, but leave together and bake until set.

Step 7

Re-cut wedges, and slide apart enough so the edges can brown as well.

Step 8

Return to oven and bake until light brown and crispy (perhaps 25 minutes total baking time).

Step 9

Cool on a rack.
