These Flourless Pecan Brownies are probably the BEST brownies I have ever eaten! I love chewy brownies and these brownies are insanely gooey and the pecans go so well with the strong chocolate flavour!
Preheat the oven to 350℉. Line a 9X9-inch baking pan with parchment paper, leaving the edges to hang over the sides of the pan.
In a large mixing bowl, beat together melted butter, brown sugar, and vanilla on high speed for 2 full minutes. Add the egg and egg yolk and continue beating on high for 30 seconds.
Add the cocoa powder, cream of tartar, and salt and beat on low speed until combined. Lastly, fold in the chopped nuts. Pour batter into the lined pan and bake in the preheated oven for 20 minutes. The brownies should look fully cooked on top but still be gooey in the center.
These brownies would be wonderful served warm with ice cream or let them cool to room temperature on the counter before chilling in the refrigerator to serve cold. I LOVE these brownies served cold, they are super chewy and fudge-like when cold! Enjoy!
