I found these recipes for microwave muffins and biscuits, you may be able to modify and experiment with it a bit to adapt it to scones.
MICROWAVE READY-BAKE BRAN MUFFINS
This is a make-ahead batter that can be stored in the refrigerator for up to two weeks.
3 c. whole bran cereal
1 c. boiling water
2 eggs, lightly beaten
2 c. buttermilk
1 c. salad oil
1 c. raisins or other dried fruit
2 tsp. baking soda
1/2 tsp. salt
1 c. sugar
2 1/2 c. all-purpose flour
In a large bowl, combine cereal with boiling water and stir thoroughly. Let cool, then stir in eggs, buttermilk, oil and fruit; blend well. In another large bowl, mix together baking soda, salt, sugar and flour; then stir in bran mixture. Cover tightly and store in refrigerator. Before using, stir batter to distribute fruit evenly.
To bake, place cup cake paper liners in 6 ounce custard cups. Spoon batter into desired number of cups, filling each half full. Place on a flat plate arranging them in a circle (or use turntable). Use table below for a guide to baking. Bake at 100%.

Time:
45 seconds to 1 minute
1 to 1 1/2 minutes
1 1/2 to 2 minutes
2 to 2 1/2 minutes
2 1/2 to 3 minutes
3 to 4 minutes
4 to 5 minutes
NOTE: Muffins should be removed from custard cups immediately and placed on rack, otherwise they will "sweat". Do not overbake or else you will have a rock. If the muffin tests done, but some moist spots are still on top, do not worry, these will dry out as muffins cool.
BAKING POWDER BISCUITS
1/3 c. shortening
1 3/4 c. all purpose flour
2 1/2 tsp. baking powder
3/4 tsp. salt
About 3/4 c. milk
Paprika topping, below
Cut shortening into flour, baking powder and salt with pastry blender until mixture resembles fine crumbs. Stir in just enough milk so dough leaves side of bowl and rounds up into a ball. Too much milk makes dough sticky, not enough makes biscuits dry.
Turn dough onto lightly floured surface. Knead lightly 10 times. Roll 1/2 inch thick. Cut with floured 2 inch biscuit cutter. Arrange 6 biscuits with sides almost touching in circle on 10 inch microwavable plate; brush tops of biscuits with Paprika Topping. Microwave uncovered on high (100%) 1 minute; rotate plate 1/2 turn. Microwave until no longer doughy, 1 to 2 minutes. Let stand 1 minute; remove to rack. Repeat with remaining biscuits. 1 dozen biscuits.
