We are the Six Sisters at Six Sisters Stuff . . . that’s right, six girls and no boys! Growing up, we had our share of petty fights over clothes, make-up, and even boys . . . but thankfully we have grown up and are now best friends. We LOVE to be together but life, jobs, school, marriage, and babies have taken us pretty far apart from each other so we use our blog to share ideas and stay in touch. Our blog is full of family recipes, fun crafts, DIY projects, and ideas for raising kids. Feel free to stop by our blog and join the sisterhood! There is always room for one more!

In honor of Alyssa’s blogiversary, we wanted to share one of our favorite brownie recipes. An anniversary isn’t complete without chocolate, right?!
