How about giving your girlfriend a personalized recipe box or cookbook? You can gather all her favorite recipes, both the ones she's written herself and ones she's found from other bloggers, and put them together in a beautiful and unique recipe book.
To make it even more special, you can add little notes throughout the book, reminding her of special moments you've shared together while cooking or eating certain dishes. Additionally, you could consider giving her a professional photography session to capture her food creations, which she can then use for her food blog or social media profiles.
Or you can get her a star map with the date of your first kiss.
