Preheat oven to 350°F (static) or 325°F (convection or for dark pans). Coat bottom and sides of 8×8 inch pan with oil or cooking spray (without flour).
In a small bowl, combine the gluten-free egg replacer powder with warm water and whisk together (or whisk eggs). Set aside.
In a large bowl, stir together oil, sugar, almond extract, and almond milk. Add the egg replacer mixture and mix well.
Whisk together the gfJules™ flour, non-dairy milk powder, baking powder and salt. Slowly stir these dry ingredients into the wet mixture bowl, then increase the mixer speed and beat for 3-4 minutes, until the mixture is lighter and well-mixed.
Pour batter into prepared pan and bake for approximately 40 minutes, or until a toothpick inserted into the center of the cake comes out clean and the sides of the cake are pulling away from the sides of the pan. The cake will be lightly browned on the top and sides.
Set aside to cool for 5 minutes while preparing the Tres Leches Sauce.
In a medium-sized sauce pot, whisk together the three “milks”: coconut, almond and kefir coconut milk. Add the untoasted coconut. Stir over medium heat on the stove until warmed — approximately 5 minutes.
Poke holes in the top of the cake with a toothpick or fork, every 1/2 to 1 inch. This perforation will help the Tres Leches sauce to seep into the cake itself. Once the sauce is warmed, pour slowly over entire cake, but do not allow it to pool in the center. Tilt the cake pan, if necessary, to help disperse the sauce, and reserve extra sauce if there appears to be too much for the cake to absorb (this may be served with the cake later, if desired).
Cover cake with plastic wrap and refrigerate until the sauce is mostly absorbed – usually 3- 4 hours or overnight.
