FAQs
Can I use natural peanut butter?
It is best to stick to creamy processed brands for the best swirl texture. Natural oils can separate and change the bake.
How do I get the perfect swirl?
Use a butter knife and don’t over-mix the colors. A few bold figure-eight motions work best for that marbled look.
Can I make these gluten-free?
Yes, you can use a 1:1 gluten-free baking flour blend. The texture will still be incredibly fudgy and delicious.
