directions

Preheat your oven to 325°F (160°C) and line a muffin tin with cupcake liners.
In a bowl, combine crushed cookies with melted butter. Press about 1–2 tablespoons into the bottom of each liner to form the crust.
In a large bowl, beat cream cheese, peanut butter, and sugar until smooth and creamy.
Mix in sour cream and vanilla extract, then add eggs one at a time, mixing just until combined.
Fold in quick oats, mini chocolate chips, and mini M&M’s.
Spoon the batter evenly over the crusts, filling each liner nearly full.
Bake for 18–22 minutes or until the centers are set but still slightly jiggly.
Cool in the pan for 30 minutes, then transfer to the fridge to chill for at least 2 hours.
Before serving, drizzle with melted chocolate and top with more mini M&M’s if desired.

Quick oats are better for texture, but old-fashioned can work if lightly chopped.
How do I know when they’re done baking?
The centers should be set but still jiggle slightly—don’t overbake to keep them creamy.
Can I make these ahead of time?
Yes, they actually taste better after chilling overnight.
Are these safe for nut allergies?
Only if peanut butter is replaced with a nut-free alternative.
What’s the best way to crush cookies?
Use a food processor or place them in a sealed bag and crush with a rolling pin.
Do I need to use a water bath?
No water bath needed—mini cheesecakes bake evenly without it.
