INSTRUCTIONS
Preheat your oven to 350°F (175°C). Grease and line an 8x8 inch baking pan.
In a large bowl, whisk together the protein powder, almond flour, brown sugar substitute, baking soda, and salt.
In a separate bowl, whisk together the eggs, melted coconut oil, and vanilla extract.
Pour the wet ingredients into the dry ingredients and mix until just combined. Fold in the white chocolate chips.
Pour the batter into the prepared pan and spread evenly. Bake for 20-25 minutes.
Let the blondies cool completely in the pan before cutting.
TROUBLESHOOTING
My brownies are too dry
Try adding 1-2 tablespoons more liquid (milk, yogurt, or egg whites). Also ensure you're not over-measuring the protein powder - use the scoop and level method.
They didn't rise properly
Check your baking powder is fresh (test by adding to hot water - it should bubble vigorously). Also, don't overmix the batter as this can deflate the air bubbles.
The texture is rubbery
This usually means too much protein powder or overbaking. Reduce baking time by 2-3 minutes and check doneness with a toothpick.
