I remember my grandma best when I’m in the kitchen. I mean I’ll never forget how she used to listen to me complain about the stresses of school or offer advice after my parent’s got divorced. But I can really picture her when I’m in the kitchen, my finger dragging down the page of one of her vaguely written recipes, whipping up some of her favorites that will never not make me think of her.

As far as Christmas cookies go there will never be a recipe better than her sandtarts. Soft but crispy butter cookies that are best served warm and practically melt in your mouth. Then there’s her cheesecake. A secret family recipe you’ll never see on the blog because it’s just that important to us. There’s pounded steak and mashed potatoes which I request every year for my birthday. Chicken and waffles {with gravy, not syrup!}, shoo fly pie, biscuit cookies, and cream cheese frosting.

Soft peanut butter fudge is one of my favorite Christmas treats and this recipe comes together super fast with just 4 ingredients! The list is endless. But when I think holidays and I think fudge I think of this soft peanut butter fudge. Just four ingredients and 10 minutes are all it takes to whip this up. Each bite melts in your mouth and takes me back to my childhood, standing on a chair helping my grandma bake at Christmastime. I was the official Hershey’s kiss unwrapper for the peanut butter blossoms. Good thing she always got extra in anticipation of me eating almost as many as I unwrapped.

You won’t need the microwave on this one but it is just as simple! I won’t call this a traditional recipe because we skip the corn syrup but the addition of marshmallow fluff is what helps this set up so fast but also keeps it creamy. You won’t want to miss this recipe!

SO happy you shared this recipe. I have it from 50+ years ago with amounts like "jar" which were different amounts than they are now. I was ecstatic to find actual amounts. Anyway, my Pennsylvania mom also added 1 tsp of vanilla and 1 tablespoon of cocoa powder (I used Special Dark cocoa powder.) Can't believe I haven't made this for at east 30 years! It's soo good!

I just made this about an hour ago and it turned out absolutely perfect. Definitely my go to fudge recipe from now on. Thank you so much for sharing this recipe

Yum! I had an issue with the texture (a bit crumbly) but I think that might be my fault and not the fault of the recipe. Do you stir the milk and sugar while it is boiling? Constantly or just scrape the sides from time to time?

I don't stir it much once it starts to boil. A crumbly texture might also mean it got too hot and the sugar cooked too much.

I found this recipe yesterday and made it this morning. It’s great! I had a different one that called for granulated sugar and it came out crumbly, but tasty. This one is nice and soft but with the same flavor. I will definitely be making it again. Thanks!

Hi, could you clarify for me the peanut butter amount(I’m familiar with grams), thanks.

It looks great!

According to Google, 16oz is roughly 454 grams :)
