Preheat oven to 350 degrees Fahrenheit and line an 8x8 inch baking pan with parchment paper.

In a large mixing bowl, combine the egg, peanut butter, sugar-free syrup, almond milk, and vanilla extract.

Whisk the wet ingredients until the mixture is smooth and emulsified.

Add the oat flour, protein powder, baking powder, and salt to the bowl.

Stir with a spatula until a thick dough forms, then fold in the chocolate chips.

Transfer the batter to the prepared pan and smooth the top with a wet spatula.

Bake for 18 to 22 minutes or until a toothpick inserted into the center comes out clean.

Let the blondies cool completely in the pan to allow the structure to set before slicing into 9 squares.
