Key Lime Pie Fudge

Curse the day I realized that fudge could have crust.

Or bless the day? I’m not really sure. All I know is that I have become totally okay with adding crust to my fudge, and now life will never be the same. And this key lime pie fudge is off the chain!

I’m going to mix business with pleasure here for a minute and rant about standardized testing. May I? Please?

Key Lime Pie Fudge

Without getting into specifics right now because I’m a teacher and I value my job, I wish to all the powers above that our nation’s politicians would just back the heck off when it comes to testing kids. It does nobody any favors. Not the kids who are being given terrible tests created by businesses and not teachers, not the teachers who have to cut down on instructional time to administer the tests, and not the parents who don’t get a full picture of what their kids are in for.

Key Lime Pie Fudge

The problem is, people don’t trust teachers, even highly qualified ones. It’s part of a cultural attitude toward a female-dominated profession, and I don’t know how to undo any of it. All I know is that unless people give teachers a little more credit for knowing what we’re doing, these tests will continue and children will cease to know what it means to think critically.

I have so much more to say, but that’s the tip of the iceberg, baby. And instead of going farther right now, I’ll just say that one of the things I love most about teaching is creativity. And that’s what I love most about baking, too.

Key Lime Pie Fudge

What is more fun than creating new desserts? This key lime pie fudge became part of my consciousness in the middle of a solitary stroll, and now that I’ve made and eaten it (way too much of it, honestly), I can tell you that it’s an experience you need to have.

This fudge has the exact same flavor as key lime pie, but from there the experience differs. While you can probably eat a couple of slices of key lime pie without feeling an unbearable sugar rush, this fudge packs a powerful punch. A little goes a long way, which is why I immediately put half on a plate and gave it away. The other half is all mine to eat my way through slowly!

Key Lime Pie Fudge

Yes, I’m greedy. But those flecks of lime zest in the fudge are irresistible. And the whole dessert lends a bright spot to an otherwise dreary time in my work life, when I have to stop teaching and proctor tests. I love teaching. It’s the best. So why does standardized testing keep ruining it?

At least I can control this fudge and keep my dessert experience pure. I recommend you do the same!


Key Lime Pie Fudge


1/4 cup butter
1/4 cup white chocolate chips
1/3 cup firmly packed brown sugar
1 cup graham cracker crumbs
2 cups white chocolate chips
14-oz. can sweetened condensed milk (I used fat free)
1/4 cup key lime juice (about 4-5 key limes)
1-2 tablespoons key lime zest (use the zest from the limes you're juicing)


  1. Preheat the oven to 350. Line an 8 x 8 pan with foil, leaving enough to hang over the sides. Spray with cooking spray. Set aside.
  2. In a microwave-safe bowl, melt the peanut butter chips and butter for 1 minute. Stir until smooth. Add the brown sugar and graham cracker crumbs, stirring until moistened.
  3. Press the crumbs tightly and evenly into the prepared pan with a spatula. Bake the crust for 15 minutes.
  4. While the crust is baking, make the fudge. On the stove over low heat, melt the white chocolate chips with the condensed milk, stirring constantly, until the mixture is melted and smooth. Stir in the lime juice and lime zest.
  5. Remove from the heat.
  6. Pour the mixture over the baked graham cracker crust, spreading carefully to even out the top.
  7. Chill for 3 hours. Let the fudge come to room temperature. Cut into squares with a sharp knife and store in an airtight container.


I fulfill many roles in life: wife, mother, teacher, everlasting learner. This site is dedicated to one role that expresses my creativity in ways that I find consistently challenging and rewarding: baker. Inventing new ways to enhance food, especially if that food involves chocolate or peanut butter (or both!), is a passion of mine. I look forward to sharing my ideas with you.

      I’m glad you’re with me, Alice. So many people think that teaching is about getting kids to memorize information, and that’s SO not what it is! We have to teach them to think. And I think crust is the best on whatever we can get it onto! 🙂

    I love this fudge. And I love the fact that it has the crust – it’s so CIVILIZED. I could really go to town on it 🙂

      Thanks, Ami! And if you can’t get key limes, regular lime will substitute just fine. You only need one lime to make this!

  6. Rachelle @ Beer Girl Cooks

    Oh. My. Goodness. Key Lime Pie is my favorite and the fact that you turned it into a fudge is mind-blowing! To heck with stupid standardized tests – let’s have some key lime fudge!

      Yes, fudge over tests wins every time, Rachelle!

  7. Cyndi - My Kitchen Craze

    All I can say being a parent to two kids is I appreciate teachers like you. You care about your job and the kids. I know most teachers are awesome, but then you find those few that have one foot out the door. I agree with the test. We start our state testing next week and ugh I hate it for the kids. It’s to much. Anyway on to yummy things. I love this fudge. I am a traditional fudge girl most of the time. This looks so awesome that I need to try is asap! Pinned! 😉

      Yep, all that is true, Cyndi! The thing is, there are bad doctors, bad lawyers, and yes, bad teachers. We just seem to get more of the bad stuff thrown our way! Anyway, thanks for the appreciation. We do value it so much!

  8. Dorothy @ Crazy for Crust

    Well, you got a hint of how I felt about testing the other day. That hint runs so deep that my husband mentions math in our house and an hour later he says “I shouldn’t have gotten you riled up.” Hate. It. With. A. Passion. And the teachers get blamed – they’re the messengers. Not fair!

    Fudge with crust is pretty much the best invention ever. LOVE this so darn much!

      The same thing happens in my house, Dorothy! My husband will bring one thing up and I’ll rant for a VERY long time. I’m so glad you feel the same way. It’s hard to not get upset!

  9. Stacey @ Bake.Eat.Repeat.

    Crust on fudge? That sounds amazing! I can’t wait to try this! And those little green key lime flecks definitely look irresistible! 🙂 Pinned!
