Gather ingredients and allow eggs to sit out for 30 minutes to 1 hour to get to room temperature, or submerse in a warm water bath for 5 minutes if you're short on time.
Preheat oven to 350 degrees and line an 8X8 square baking pan with parchment paper.
In a medium mixing bowl, whisk together almond flour, coconut flour, baking powder, and sea salt.
In a large mixing bowl, mix with a spatula brown sugar replacement, granulated sugar replacement, sunflower seed butter, and coconut oil. Add eggs and vanilla extract and stir until smooth.
Add your flour mixture slowly to your sugar mixture. Fold until just about mixed, then fold in the chocolate chips. Careful not to overmix.
Divide dough in half reserving one-half for the top layer. Press the other half into the bottom of the prepared 8X8 parchment lined square baking pan.
Spread Suntella over the bottom layer with a pastry knife.
Sprinkle reserved dough over the top. Top with sunflower seeds and sea salt if desired (highly recommended for optimal tastiness)
Bake for 22-25 minutes on middle rack until golden brown. Take out of oven and allow to cool completely before cutting into bars and serving.
