Preheat oven to 325 degrees Fahrenheit. Line a 8x8 or 9x9-inch baking pan (round or square) with parchment paper.

In a bowl, combine eggs and sugar. Using a hand mixer or stand mixer, beat until fluffy, approximately 3 to 4 minutes.

Mix in almond flour, coconut flour, cacao, Cordyceps, and vanilla and stir until combined.

In a microwave-safe bowl, add ¾ cup chocolate chips and coconut oil. Microwave for 1 minute, mix, then microwave in 15-second bursts until melted, stirring between each. Pour into brownie batter and mix well. Stir in remaining ¼ cup chocolate chips.

Pour brownie batter into pan and bake 35 to 40 minutes, until a toothpick inserted comes out with moist crumbs.

Allow to cool at least 15 minutes prior to cutting. Use parchment paper to lift out of pan then cut on a cutting board.
