Mix the flour, wheat germ, baking soda and salt in a bowl.
In another, larger bowl, whisk together the sugar, maple syrup, almond milk, mashed bananas and vanilla extract until well-mixed.
Add the flour mixture in three batches, stirring thoroughly after each addition. Fold in the toasted, chopped walnuts.
Pour the thick batter into a greased 10-inch Bundt pan, or use a suitable silicone Bundt pan. Smooth the top.
Bake in a preheated 350-degree Fahrenheit oven for 45 minutes or until a toothpick inserted near the cake's center comes out clean.
Cool thoroughly, unmold, dust with some confectioner's sugar if you like, then slice. Serve with some vegan whipped cream for some extra oomph, or just plain-- it's delicious either way.
