Preheat the oven to 350° F (175°C). Grease the bottom of an 8x4-inch loaf pan.
Melt together the almond butter and coconut oil in a microwaveable mixing bowl in the microwave for 30-60 seconds on high or in a small saucepan on stovetop over medium high heat. Allow to cool a few minutes, if needed, to prevent the egg from cooking in batter.
Mix in the cocoa powder and sweetener.
Stir in egg, vanilla, and salt.
Fold in the coconut flour until well incorporated. Press batter into the prepared loaf pan and sprinkle chocolate chips evenly over the top.
Bake in the preheated oven to the desired doneness, about 15 minutes. For fudgy brownies, the inside should be kept slightly moist.
Notes
Don't overbake the brownies! For the fudgiest, most delicious texture, keep a close eye on them and remove from the oven when the center is slightly moist.Make sure your egg and almond butter (or sunflower seed butter) are at room temperature before mixing to ensure smooth batter and even cooking.Sifting coconut flour helps prevent clumps and ensures it mixes evenly into the batter for the best texture.Let the brownies cool in the pan for at least 10 minutes before cutting to allow them to set properly and hold their shape.If you're experimenting with sweeteners, start with a smaller amount and adjust to taste, as some sweeteners can be much sweeter than sugar.
