THE COOKIE PIE SYSTEM™
Thick. Stuffed. Structured. Built to Sell.
I’m going to say this upfront so we’re clear:
Once you make one of these…
you’re not going back to regular cookies. Well, you might, but this will stick with your customers for a long time.
This is the thick, deep-dish, borderline-illegal kind of bake.
The kind you slice cold so it holds together—but eat warm so it melts in your mouth a little.
And before you ask—yes, this is the same style that started blowing up at markets years ago over in the UK. Big, stuffed, overfilled, “how is this even holding together?” cookie pies.
We’re not doing shortcuts here.
We’re doing it the way that actually works.
Let Midnight Bakers Society be the first to help provide some insight here in the US to the cookie pies taking the UK by storm!
BEFORE YOU TOUCH THE MIXER
This recipe is different.
This is not:
a giant cookie
a skillet cookie
or a cookie cake
This is a sealed, filled, structured cookie pie.
Bottom crust.
Filling.
Top lid.
Baked low and slow so the inside stays soft and the outside doesn’t collapse.
If your past attempts turned into:
greasy puddles
raw centers
or cracked chaos
…yeah, we’re fixing that today.
We’re using:
cold butter
high structure baking ratios
cornstarch for softness & stability
Which means:
less spread
thicker bakes
stronger walls for fillings
This isn’t guesswork. This is controlled chaos.
THE BASE DOUGH
Metric (Recommended for accuracy)
227g unsalted butter, cold & cubed
213g light brown sugar
100g granulated sugar
2 eggs
5g vanilla extract
340g all-purpose flour
25g cornstarch
¾ tsp baking soda
¾ tsp salt
200g milk chocolate chips
200g semi-sweet chocolate chips
Cups Version (Still solid)
1 cup (2 sticks) cold butter, cubed
1 cup packed light brown sugar
½ cup granulated sugar
2 eggs
1 tsp vanilla
2¾ cups flour (spooned + leveled)
3 tbsp + 1 tsp cornstarch
¾ tsp baking soda
¾ tsp salt
1 cup milk chocolate chips
1 cup semi-sweet chocolate chips
STEP-BY-STEP PROCESS
1. Cold Butter + Sugar Phase
Add cold butter and both sugars to your mixer.
Mix on medium for ~5 minutes.
You are NOT aiming for fluffy.
You want:
creamy
slightly textured
no large butter chunks
This step controls:
spread
thickness
final structure
2. Eggs
Add eggs one at a time.
Mix until smooth and slightly lighter in color
This builds:
elasticity
binding
overall dough cohesion
3. Vanilla
Add, mix, scrape, mix again.
You’re looking for smooth. No lumps.
No weird streaks.
4. Dry Ingredients
Add:
flour
cornstarch
baking soda
salt
Mix on low speed. Don’t overwork it.
You want:
soft dough
not sticky
not wet
If it feels like thick frosting, you messed up.
If it feels like playdough, you’re in the zone.
Stop the second flour disappears.
Overmixing = tough cookie
Undermixing = uneven bake
5. Fold in Mix-Ins
Use a spatula. Mix just enough to distribute.
Don’t annihilate your dough trying to be perfect.
6. Chill
Refrigerate:
minimum 4-6 hours
Overnight is better.
This is not optional.
This is what:
deepens the flavor
firms the dough
makes rolling possible
prevents collapse in the oven
If you skip this, your cookie pie will humble you.
BUILDING THE COOKIE PIE
What you need (don’t overthink it)
7–8 inch round tin (loose base like a springform pan helps a LOT)
Mixer (hand or stand)
Parchment
Rolling pin (or a wine bottle, I’m not judging)
1. Line Your Tin
Parchment circle on the bottom.
Saves your sanity later.
2. Base Layer
Take 250–300g dough
Roll it out and press it into the tin:
bottom covered
sides come up (but not all the way to the top)
It will crack. It will look messy.
Fix it with your fingers, this is meant to be a very basic and forgiving dough.
2. Fill It
This is where you stand out and other people play it safe.
Options:
Biscoff
Nutella
Ganache (find our free ganache guide here!)
Fudge (check out our fudge filling here , but any fudge recipe will do. chill to firm between layers if using more than 1 fudge flavor)
Peanut Butter
Marshmallow Fluff
The original example uses Biscoff …but honestly?
Put whatever you want in there.
Just don’t overfill to the point you can’t seal it.
Texture Add-Ins:
chopped candy bars
cookies
brownies
pretzels
Think in layers, not just filling
3. Top Layer
Use 200–250g dough
Roll it out. Lay it on top.
Now seal it like your life depends on it:
press edges together
push sides slightly lower than center
This gives you that signature dome top instead of a flat disaster.
BAKING
Oven Settings
Fan oven: 160°C (~320-325°F) → ~20-24 minutes
Conventional: 180°C (~350-360°F) → ~22-28 minutes
Low and controlled. Not aggressive.
You’re not trying to “cook it through”—
you’re trying to set the structure while keeping the inside soft.
What You’re Looking For:
golden edges
slightly soft center
set top
👉 DO NOT overbake
It continues cooking as it cools
COOLING
This is the hardest part. Seriously.
You have to wait.
Cool at room temp for a couple hours (2-4 hours)
Then chill for at least 6-12 additional hours (overnight is best)
This is what gives you:
clean slices
defined layers
that thick bakery look
If you cut it warm, it’ll still taste amazing…
…but it’ll look like a crime scene.
HOW TO SLICE (YES THIS MATTERS)
Use:
sharp knife
wipe between cuts
You want to slice it like a cheesecake, not a cookie.

SELLING
This is not just a recipe.
This is a high-margin product.
Why it works:
visually impressive
sliceable → portion control (this recipe creates 6-8 BIG slices!)
customizable → endless menu
Sell it as:
whole pies
slices
seasonal drops
Slices = higher profit per batch
COMMON MISTAKES
skipping chill → collapse
overfilling → leaks
underbaking edges → raw structure
cutting warm → disaster
FINAL WORD
This isn’t just something you bake.
This is something you can:
build a menu around
turn into cookie bars
sell consistently
turn into a signature item
And once you understand the method?
You can start going completely unhinged with flavors.
If you’ve made it this far…
You’re officially past the point of making normal cookies.
Welcome to the deep end.
