01 - Preheat oven to 350°F. Line a 12-cup muffin tin with paper liners or grease lightly.
02 - In a large bowl, mix oats, almond flour, cocoa powder, sea salt, and baking powder until evenly blended.
03 - In a separate bowl, whisk melted coconut oil, maple syrup, brown sugar, eggs, and vanilla extract until smooth and incorporated.
04 - Pour wet ingredients into dry mixture. Stir gently until just combined, being careful not to overmix.
05 - Gently fold dark chocolate chips and nuts into batter until evenly distributed.
06 - Divide batter evenly among prepared muffin cups, filling each about 3/4 full.
07 - Bake for 18-20 minutes until centers are set and a toothpick inserted comes out mostly clean. Slight chocolate streaks are acceptable.
08 - Let cool in pan for 10 minutes, then transfer to wire rack to cool completely before serving.
