Dissolve dry yeast in warm water in a small bowl. Set aside for 5 minutes to proof.
In a large bowl, sift together flour, baking soda, baking powder, sugar, and salt. Cut shortening into flour mixture with a pastry cutter or two knifes or use your hands (like I did!). Add the buttermilk, the yeast mixture, and the shredded cheddar cheese. Dump dough onto floured surface and knead for a couple of minutes. Roll out and cut with biscuit cutter into 2- 2½ inch biscuits. Place biscuits on a lightly greased baking sheet and let rest for 5 minutes.
Bake for 12-15 minutes, or until lightly brown. Brush with garlic butter and serve immediately.
FOR THE GARLIC BUTTER:
Melt butter in a small saucepan or in microwave. Stir in the garlic powder. Place any butter leftovers in covered container and store in the refrigerator.
