Preheat oven to 350 degrees F. Line the bottom and sides of an 8-inch square baking pan with parchment paper.
Place butter and 1/4 cup chocolate chips in a large microwave safe bowl and microwave in 20 second intervals, stirring after each, until melted and smooth. Set aside to cool completely.
When chocolate and butter are cool, whisk in granulated and brown sugar. Add eggs, 1 at a time, whisking until just combined. Whisk in vanilla, then almond flour, cocoa powder, baking powder, and salt.
Pour batter into prepared pan, then sprinkle top with 1/2 cup chocolate chips.
Bake brownies for about 35-45 minutes at 350 degrees F or until toothpick interested into center comes about clean or with a few crumbs.
Cool completely, then lift brownies out of pan using parchment paper. Remove paper and cut into squares.
SNAPPY TIPS: Instead of parchment paper you could use nonstick aluminum foil, or grease your pan if needed. SNAPPY SUBSTITUTIONS: Instead of dark chocolate chocolate chips, you could use bittersweet or semi-sweet chocolate chips.
