Preheat oven to 350 F. In a large bowl, mix the egg and coconut together with a stiff whisk or a mixer until thick and creamy. This may take a minute or two. You want the mixture to resemble peanut butter (see above image in step 1 for reference).
1 egg, ½ cup coconut sugar
Add the peanut butter, almond milk, and vanilla. Continue to mix until the peanut butter is fully incorporated into the batter and there aren't any large chunks.
½ cup creamy peanut butter, ¼ cup almond milk, 1 teaspoon vanilla
Fold in the almond flour, tapioca flour, and baking soda with a rubber spatula. Be careful not to over mix the batter. Fold until no flour clumps remain.
1 cup almond flour, ¼ cup tapioca flour, ½ teaspoon baking soda
Add the Valentine's M&Ms and chocolate chunks and give the batter a few large swirls to incorporate them. Line an 8x8 inch baking pan with parchment paper and pour in the batter. Level off the top with a spatula and "drop" the pan on the counter a few times to get any air bubbles out. Bake in the oven for 16 - 20 minutes until golden brown. Sprinkle with sea salt and let cool slightly before slicing into bars.
