🥔🍰 GRANDMA’S SECRET MASHED POTATO CHEESECAKE
WHO PUT MASHED POTATOES IN MY CHEESECAKE?! 😳😂
Grandma would probably have a few words about this one…
Imagine a classic New York-style cheesecake with a buttery Graham cracker crust, silky cream cheese filling, and rich salted caramel dripping down the sides. 🤤
Sounds perfect, right?
Well… there’s a SECRET ingredient.
REAL MASHED POTATOES! 🥔
Not on the side. Not sprinkled on top.
INSIDE THE CHEESECAKE!
The experiment? See whether a little perfectly smooth mashed potato can add body and tenderness to a traditional cheesecake without making it taste like Thanksgiving dinner.
Is this genius… or have we officially gone too far? 😂
Let’s put it to the test!
🍰 INGREDIENTS — 8 TO 10 SERVINGS
For the Graham Cracker Crust:
* 1 1/2 cups (160 g) Graham cracker crumbs
* 5 tbsp (70 g) unsalted butter, melted
* 2 tbsp granulated sugar
* Pinch of salt
For the Cheesecake Filling:
* 21 oz (600 g) full-fat cream cheese, softened
* 3/4 cup minus 1 tbsp (140 g) granulated sugar
* 3 large eggs, room temperature
* 1/2 cup (120 g) full-fat sour cream
* 1 tsp vanilla extract
* 3 1/2 oz (100 g) plain mashed potatoes, completely cooled
IMPORTANT: The mashed potatoes must contain NO garlic, salt, pepper, cheese, milk, or butter. Use plain boiled potatoes mashed until completely smooth.
For the Salted Caramel Topping:
* 1/2 cup thick caramel sauce
* A tiny pinch of flaky sea salt, if the caramel is unsalted
👩🍳 HOW TO MAKE IT
1️⃣ MAKE THE SECRET POTATO INGREDIENT 🥔
Peel and dice a small starchy potato, such as a Russet.
Boil in plain water until completely tender.
Drain thoroughly and let excess steam evaporate.
Press the potato through a fine potato ricer or sieve until smooth.
Measure 100 g and allow it to cool completely.
There should be absolutely NO lumps.
2️⃣ PREPARE THE CRUST
Preheat the oven to 325°F (160°C).
Lightly grease an 8-inch (20 cm) springform pan and line the bottom with parchment paper.
Mix Graham cracker crumbs, melted butter, sugar, and salt.
Press firmly into the bottom of the pan.
Bake for 10 minutes, then set aside to cool.
3️⃣ MAKE THE CREAM CHEESE FILLING 🤍
In a large bowl, beat the softened cream cheese and sugar on low speed until smooth.
Add the completely cooled mashed potatoes.
Mix gently until fully incorporated.
Add sour cream and vanilla.
Blend until smooth, scraping the sides of the bowl.
4️⃣ ADD THE EGGS
Add the eggs one at a time, mixing on low speed just until combined.
Avoid whipping too much air into the batter.
The mixture should be smooth, thick, and creamy.
5️⃣ BAKE THE CHEESECAKE 🔥
Pour the filling over the prepared crust.
Smooth the surface.
Place the springform pan on a baking sheet and put a separate pan of hot water on a lower oven rack to create a humid baking environment.
Bake for approximately 55–70 minutes.
The edges should look set while the center still has a gentle wobble.
Turn off the oven, crack the door slightly, and leave the cheesecake inside for 30 minutes.
6️⃣ CHILL UNTIL SET ❄️
Remove from the oven and let cool to room temperature.
Cover and refrigerate for at least 6 hours, preferably overnight.
This step is essential for clean slices and a properly set cheesecake.
7️⃣ ADD THE SALTED CARAMEL 🍯
Carefully remove the chilled cheesecake from the pan.
Spoon the caramel sauce over the top.
Let a little drip naturally down the sides.
Finish with a tiny pinch of flaky sea salt if needed.
Slice with a warm, clean knife.
And there it is…
A beautiful caramel cheesecake hiding one of the most controversial ingredients Grandma could imagine. 🥔🍰
🧪 THE RECIPES DADDY EXPERIMENT
This is an original recipe prototype, not a guaranteed improvement over traditional cheesecake.
Mashed potatoes contain starch and moisture, which may change the texture of the filling.
But too much potato could make the cheesecake dense, gummy, or noticeably starchy.
For a fair test, prepare two small cheesecakes:
🍰 VERSION A: Traditional cheesecake without mashed potatoes.
🥔 VERSION B: Cheesecake with mashed potatoes.
Taste them blind and compare:
* Creaminess
* Smoothness
* Sweetness
* Aftertaste
* Overall preference
Only the actual taste test can tell us whether Grandma would approve!
