Place dates in a small bowl and cover with boiling water to soften.
Preheat oven to 350 degrees F. Using parchment paper, line an 8 x 8 baking dish.
Drain dates, add to large bowl along with bananas. Mash both together - chunks are ok! Add sweetener, coconut oil, lime juice, and vanilla. Whisk to combine.
In a separate bowl, whisk together all dry ingredients. Sift into the wet ingredients and fold gently until combined. Mixture will be thick and goopy - that's fine! Try not to over mix.
Pour into prepared pan and bake for 25 minutes, or until toothpick comes out clean. Cool before slicing and serving! If you'd like, you can serve drizzled with melted chocolate!
