This weekend, I thought my house was blowing up. Legitimately. Somehow, a transformer exploded across the street from us and the explosion occurred just as I was turning off a light in my house. I heard a huge boom, saw super bright colorful flashes of light, and felt the house shake. “OMG did I blow up our house?!?!” I frantically yelled to Chris as I tried to determine the quickest way out. But when we opened the door, we realized it happened across the street and there was a small fire on the electric wires and another on the ground. We called 911, waited for the firetruck to arrive and thanked our lucky stars that not only was our house not blowing up, but our electricity wasn’t even out. 

I’m also thankful that my turning out the light had nothing to do with this turn of events. So, why did it happen? Well, I don’t know, but I do know that we saw three huge turkeys in our yard the evening before. And that our neighbor claims she saw a turkey roosting on top of the wires that night. Huh. This is seriously concerning, right? Turkeys are allegedly setting fires in my neighborhood and attempting to destroy homes. Needless to say, I required a glass of wine and lots of cheese that evening. Luckily, we went to celebrate Father’s Day at my sister’s house and enjoyed lots of wine and cheese, along with the company of the best dad in the world and my my fabulous aunt and uncle who were visiting. My Sunday was redeemed.

And now I’m here to blog about more cheese. LOTS of cheese. But better than that. This is an appetizer that contains all of my favorite things in one glorious little bite. Is this what heaven is like? I hope so. They’re Cheddar Cups with Avocado Feta Mousse and they make a pretty ideal app. Plus, they have baked kale on top. The only thing that could make them better is if wine was somehow baked in. I’ll start working on that

I’m lucky enough to be in Cabot’s Cheese Board, which means Cabot sends me cheesy treats on occasion. These three varieties of aged cheddar are my new obsession.

For this recipe, I went with the White Oak Cheddar, one of my all-time favorite cheeses. Swoon. I used an entire block of it.

So, you should know that my husband has an obsession with parmesan goat cheese crisps; the ones they make at the French Laundry. But more specifically, the ones from the French Laundry that our friend Jeff makes at every one of his and Kyle’s wine parties. Sometimes it’s a total embarrassment because Chris eats the entire platter of them within the first hour of the party. I’m pretty sure they have taken to hiding extras, so that Chris can’t find them.

I should probably make them myself, but I just love seeing how excited he gets every time we go to a party at their house, so I want to keep that novelty alive. But I started wondering if I could do the same type of thing with cheddar cheese… And you can! Instead of just crisps, I decided to make cups and then I filled them with an avocado feta mousse. Because yum.

Basically, you make little circular mounds of the grated cheddar on a parchment or Silpat-lined baking sheet. Make sure they’re spaced at least an inch apart.

 Then bake them at 350 degrees for about 8-10 minutes, until cheddar is flattening out and turning golden.

Let the rounds sit for 30-60 seconds, until you’re able to pick them up with a spatula and place into a muffin tin. Timing is important now as you don’t want the cheese to be too gooey, but you also don’t want it to harden before you get it in the tin… And it hardens quickly!

Let the cheese cups cool in the muffin tin before removing. I’d say these are a tad bit tougher to make than parmesan cups because parm is a harder and drier cheese, making them a little bit more ideal for baking and forming. But still, worth it!!

The mousse filling is about the easiest thing ever! Just put 2 peeled and pitted avocados, 1/2 cup crumbled feta cheese, 1 Tbsp freshly squeezed lime juice, 6 Tbsp milk, and 1/4 tsp black pepper in a blender or food process. Blend away until smooth and creamy!

And then bake up that kale. Take 2 cups of kale and 1 1/2 Tbsp olive oil and mix them together in a bowl with some red pepper flakes and pinch of salt. Then spread the kale in a single layer on a baking sheet and bake at 350 degrees for about 16-20 minutes, until nice and crispy.

Remove from oven and let cool.

Now all your components are ready and it’s time for the assembly. You can either pipe the avocado feta mousse into the cheddar cups or you can simply spoon it in. Just don’t forget to top with some crispy baked kale!

I honestly think that if I could only choose a few foods to live on for the rest of my life, cheese, avocado, and kale would be on the list. I actually really, really do like kale. I mean, not as much as cheese, but I legitimately Googled, “Is kale addictive” the other day because I think I may have a problem. I crave it so much and eat way too much of it. I’m chalking that up as a good problem to have, but it’s kind of freaking me out.

So, put kale in a cheese cup AND add in plenty of avocado and I’m for real swooning. Cheese cups!! Like there is one ingredient in those… Cheese. I can’t get over that. And the Cabot I used was the perfect amount of sharpness, which I think is pretty key for these cups!

If you’re planning to serve these at a party, I seriously recommend making extra because you may have no idea how much cheese you’re able to eat until you start eating these. I also recommending drizzling a little lime juice over the top. While I don’t think these apps will be sitting around your party for long, the lime juice will give them a little protection from browning.

It was definitely a mistake for me to learn how to make these. Too easy and ridiculously dangerous. What wouldn’t be delicious in a cheddar cup??

These cheddar cups could definitely help you overcome all sorts of bad days… Probably not a home explosion caused by turkeys, but lots of other stuff. They certainly make me pretty happy!

What three foods would you choose to live on for the rest of your life?

Cheddar Cups

  • 1 block (6 oz.) Cabot Cheddar Cheese, grated

Avocado Feta Mousse:

  • 2 avocados, peeled and pitted
  • 1/2 cup crumbled feta cheese
  • 1 Tbsp freshly squeezed lime juice
  • 6 Tbsp milk
  • 1/4 tsp black pepper

  • On a parchment paper or Silpat-lined baking sheet, scatter shredded cheddar in small circular mounds, spaced at least an ounce apart.
  • Bake at 350 degrees for about 8-10 minutes, when cheese is just turning golden.
  • After removing from oven, let sit for 30-60 seconds and then lift cheddar rounds with spatula and fit into muffin tins. Press down to form cheese into cups. It's important wait 30-60 seconds before moving, so cheese isn't gooey, but then you must work quickly before it hardens completely.
  • Cool completely and then remove from muffin tin.
  • Spoon or pipe avocado feta mousse into each cup and top with crumbled baked kale.

Avocado Feta Mousse

  • Places avocado, feta, lime juice, milk, and black pepper in a blender and blend until a smooth mousse is formed.

Baked Kale

  • Place kale leaves in a bowl and toss together with olive oil and red pepper flakes, and salt.
  • Once kale is coated, spread leaves in a single layer on a baking sheet and bake at 350 degrees for about 16-20 minutes, until nice and crispy.
  • Remove from oven and let cool.


  • If these cheddar cups will be sitting out at a party, you may want to squeeze a little fresh lime juice over them to prevent the avocado mousse from browning.

  1. Yum! That was literally my reaction when I saw these. Could gobble (turkey reference haha) these up in one go!

  2. Firstly, I would have wet myself had I heard that explosion, and I am so glad you are all OK! Secondly, I cannot believe how easy the cups are to make. So worth trying. The mousse is my favourite way to eat avocados, with a bit of dill added to the mixture 🙂

    Can the cheese cups be made a day in advance and would they need to be refrigerated?

    Recipe looks awesome and I plan on making for my wife’s birthday party.

    Thank you,

  26. Sues says:

    @Rick- Hello! I haven’t tried making these in advance, but that should be totally fine! I’d place them in an airtight container with layers of waxed or parchment paper between them. You should leave them at room temperature as the fridge will make them too moist and soggy. I hope you enjoy them and happy birthday to your wife 🙂

    Shred the cheese the long way, down the whole length of it, to skip a step. The long shreds lay nicely over the humps on the back/underside of a mini muffin pan. 😉

    Now it’s even easier to make these….lol

    Has anyone made these a day in advance? Please let me know!
