I went to the gym and ran my little heart out…then I came home and made these Buckeye Brownies. So I guess I’ll just call it even…if I’m lucky.
Whenever I’m on the treadmill I think if I could just keep myself from eating everything I wouldn’t have to run so hard. Uggh. My life struggle.

I have yet to meet a truffle I didn’t like so I was really excited about these brownies. Our first year of marriage John bought me about 40 truffles for Valentine’s day. By lunch, they were gone.


I remember seeing John’s shocked face when he realized they ALL were gone. He must have underestimated my love for chocolate when he married me.

Too bad I don’t have the metabolism now that I did back then.

After dinner tonight I went to the fridge to taste them for a second time and all that was left was a plate with crumbs on it so it must have been a hit with the whole family.




Peanut Butter Truffle Brownies - they taste like a buckeye on top of a brownie.

Prep Time: 15 mins
Cook Time: 20 mins
Total Time: 35 mins
Servings: 16 brownies


Brownie Base:

  • 1 (1 lb 6.5 oz) box Betty Crocker® Original Supreme brownie mix
  • Water, vegetable oil and eggs called for on brownie mix box


  • 1/2 cup butter, softened
  • 3/4 cup creamy peanut butter
  • 2 cups powdered sugar
  • 2 teaspoons milk


  • 1 cup semisweet chocolate chips
  • 1/4 cup butter


  • Heat oven to 350°F. Grease bottom only of 13×9-inch pan with cooking spray or shortening. (For easier cutting, line pan with foil, then grease foil on bottom only of pan. I do this all the time when I make brownies and bars)
  • In medium bowl, make brownie mix according to the package directions. Spread in pan. Bake according to package directions. Cool completely, about 1 hour. You can speed this up by cooling in the refrigerator.
  • In medium bowl, beat filling ingredients with electric mixer on medium speed until smooth. Spread mixture evenly over brownie base.
  • In small microwavable bowl, microwave topping ingredients uncovered on High 30 to 60 seconds; stir until smooth. Cool 10 minutes; spread over filling. Refrigerate about 30 minutes or until set. For brownies, cut into 9 rows by 4 rows. Store covered in refrigerator. (I take it out or the fridge about 15 minutes before serving. This allows the chocolate on top to soften a little)
