- 9 Tbsp. butter
- 1/2 cup superfine sugar
- 1 large egg , preferably free-range or organic
- Scant 1 cup all-purpose flour
- 1/4 cup quick cook oatmeal (not instant)
- 1/4 tsp. baking powder
- 1/2 tsp. salt
- 1 orange
- 1 lemon
- 2 ounces white chocolate or 1/4 cup white chocolatechips
- 2 ounces bittersweet chocolate or 1/4 cup bittersweet chocolatechips
To flavor cookie dough: Either finely grate your orange and lemon zest or roughly chop your chocolate. Stir the zest or chocolate into the cookie dough and mix together well. Spoon on to a piece of plastic wrap and roll into a sausage shape with a roughly 2 1/2-inch diameter. Pop the dough into the freezer for 30 minutes.
To bake cookies: Preheat the oven to 375°. Get your chilled dough out of the freezer and cut it into 1/4-inch-thick slices. Place these on two nonstick cookie sheets, making sure you leave a good bit of space between the slices because they'll spread while cooking. If you can't fit all your slices on the cookie sheets, just cook one batch after another. Place the cookie sheets in the middle of your preheated oven and bake for 8 to 10 minutes, until the edges of the cookies are golden brown. Let them cool down slightly before transferring to a wire rack to let cool completely and crisp up. Delicious with a glass of cold milk.
