1¼ cups whole wheat flour plus additional for flouring pan
6 Tablespoons dark unsweetened cocoa powder plus additional for dusting
1 teaspoon baking powder
½ teaspoon baking soda
¼ teaspoon salt
¾ cup water
½ cup pureed blueberries (or blueberry preserves)
1 egg
½ cup simple syrup, or honey (to make simple syrup, heat ½ sugar and ½ cup water in a sauce pan and stir until sugar dissolves completely. Do not boil)
Butter or oil for greasing the dish
Additional berries for serving
Instructions
In a large mixing bowl, combine dry ingredients. You can sift them together if desired, but I usually don't.
In a smaller bowl, whisk wet ingredients until thoroughly combined
Add wet ingredients to dry ingredients, and stir until smooth
Grease a casserole dish that fits in your pressure cooker with butter, and coat with flour
Pour batter into casserole dish
Cover dish tightly with foil
Make foil handles to help you remove the casserole dish after cooking (see above!)
Place a trivet or foil coil in the bottom of the pressure cooker (to prevent the casserole from touching the bottom)
Pour 2 cups of water plus 1 tablespoon of vinegar in the bottom of the cooker (the vinegar prevents the white milky coating from happening in the cooker, your food will not taste like vinegar)
Place casserole in pressure cooker, and close and lock lid
Set the pressure cooker on high pressure (or use the rice/vegetable setting) and set the timer for 14 minutes. Start the cooker.
After the cooker is done, allow the pressure to release naturally (don't do anything, just let it sit until you can open the lid)
Use the foil handles you created to remove the casserole dish and remove the foil covering.
Once cool enough to handle, loosen the cake with a knife and turn onto a rack to cool
Dust with cocoa powder to serve
To get the flat top, I simply held my knife level and cut the "bump" off the top of the cake, then placed it upside down on the cake platter.
