My boys went through a phase where they loved Butterfingers. We made Butterfinger shakes, muffins, cookies and experimented with different bars; this one was voted the best of the bunch. Make sure you have an extra candy bar on hand because it’s hard to resist a nibble or two while you’re chopping. —Barbara Leighty, Simi Valley, California

"Expensive , time-consuming, dry, and a boring taste!"

"This is the worst cookie I've ever made and I've been baking for over 60 years. It is expensive, takes way too much time to make and the end result is something I would be reluctant to serve and admit I made."

"Thought the bars were very dry. I couldn't taste the Butterfingers, only peanut butter and bettersweet chocolate. I'll just make a cake and sprinkle the batter with crushed Butterfingers, next time"

"I'm rating this as a 5* recipe! I used a dark chocolate fudge cake mix & I used creamy peanut butter instead of chunky peanut butter. I also crushed the Butterfinger bars in my food processor: 2 for the balance of the cake mix mixture, 3 for sprinkling over the crust and 1 for the topping. I did keep the amount of chocolate chips the same: 1 cup for balance of cake mix mixture and 1/2 cup for the topping. I did grease AND flour the 15x10x1" baking pan and baked 25 minutes, then I baked 5 more minutes, using a cake tester! The bars tested done at 30 minutes for me. I plan to take the bars to my volunteer assignment at the hospital & I'll see how they like them! I admit that these bars did take longer to prepare than 20 minutes, considering that the candy bars were crushed in my food processor and the bars were prepared in the layers! Thank you, Barbara Leighty, for taking the time to share this recipe! I had been wanting to try it out and today was the time to do it!! I did sample 2 and they were reasonably firm! I did purposely try cutting into bars ahead of time to see how well they'd go through being cut! I used my brownie bar cutter to cut the balance of these bars and for the first row of bars, I'd used a sharp paring knife. These bars turned out to be delicious! I found that the yield was 38 bars!"

"We don't have Butterfinger bars in Canada, can you suggest a substitute?"
