Ingredients pre-boil.
I sublet my apartment this summer, and when I returned, there were four cans of Dr Pepper in my fridge. I can probably count on one hand the sodas I really do not care for, and sadly (non-Dublin) Dr Pepper is among them. Dumping all four cans down the drain seemed like a colossal waste, not to mention sort of a sin against the Lone Star State.

Perhaps, I thought, I could incorporate the Dr Pepper into a baked good. A few years ago, I found myself in a similar situation with a can of Guinness and as a result, I learned how to make Guinness cake, now my go-to dessert for St. Paddy's day parties. A quick perusal of the interwebs yielded many, many recipes for Dr Pepper cake and cookies, but my deficient pantry stores meant I'd have to go for something extremely simple. Eventually, I found an uber-easy recipe for Dr Pepper Peanut Brittle.

Dr Pepper Peanut Brittle

  • 1 1/4 cup sugar
  • 3/4 cup butter or margarine*
  • 1 1/2 teaspoon salt
  • 1/4 cup Dr Pepper
  • 2 cups peanuts
  • 1/2 teaspoon baking soda

Combine sugar, butter, salt, Dr Pepper and peanuts in a large saucepan. Boil, stirring constantly, until temperature of 290 degrees is reached. Remove from heat and stir in baking soda. Pour into 15 x 10 inch baking pan greased or lined with foil. Cool until hardened. Break into pieces.

Cool and ready for consumption.

Serving recommendation: Pair with ice-cold milk or hot cinnamon tea.

* Margarine was what I had, so that's what I used. Butter is surely better, although my version was tasty.

Dr. Pepper makes a great marinade for salmon.  Actually no it doesn't.


You dont like Guiness - that makes me sad.


I already tweeted this, but it seems appropriate here as I am also of the anti-Dr Pepper persuasion, but I also am a fan of the Homesick Texans Dr Pepper ribs.

Oh no, my dear. I don't like Guinness in a can. Tastes totally different on tap, and, in fact, in Ireland.


Guinness anywhere outside of Ireland tastes so sad and pathetic. Ok, I might be exaggerating, but it's not even close to the original.
