Preheat the oven to 350 °F
Lightly spritz a 6-inch cake pan with nonstick spray. Sprinkle about 1 teaspoon of flour into the pan and shake it around until the inside of the pan is completely coated in flour. Dump out any extra flour, and tap the pan a few times to make sure all the extra flour comes out.
In a large bowl, whisk together the flour, cocoa powder, sugar, baking soda, salt, and instant coffee
In another bowl, whisk together the water, applesauce, canola oil, molasses and vanilla extract.
Pour the wet ingredients into the bowl with the flour mixture. Use a spatula to stir the wet and dry ingredients together until completely combined.
Pour the batter into the prepared cake pan, and use the spatula to smooth the batter around so it's evenly distributed.
Put the cake in the oven to bake for about 50 minutes -- and watch it closely; it can get dry if it burns.
The cake is done when a knife or skewer inserted into the center comes out clean.
Place the cake, in its cake pan, onto a cooling rack for about 15 minutes.
After 15 minutes, the cake should be cool enough to remove from the pan. Run a dull knife (like a butter knife) around the edge of the pan to make sure the edges of the cake aren't stuck to the pan. Flip the pan upside down and gently slide the cake out. If you prepared the pan properly with the non-stick spray and flour, the cake should pop right out.
Set the cake back on the cooling rack to cool for another hour before you try to frost it (frosting melts off of hot cakes.)
