  1. Wow! These sound delicious! Can’t wait to try them!

  2. I was just curious, you have 1 cup softened butter and then underneath 1 cup of butter, is that a typo?? Looks delicious, was going to try this!!

  3. So delicious!! What a great treat for his class!! Thanks for the recipe!!

  4. Those look delicious. I am not much of a peanut butter fan but my hubby could eat an entire jar! I may need to try those out!

  5. Janelle, These brownies look irresistible!! My family would love the peanut butter twist!
    Also, I just read your latest post about valleys in life. I can really agree with you 100% about it all. The Lord just rescued me last month from a very long standing tribulation I walked through… He is my Savior and Redeemer!!! I want to sing His praises and be that much more prepared for anything ahead. I know He will see me through. :)
