If you’re looking for a dessert that feels like a warm hug but tastes like a gourmet bakery find, this recipe for my peanut butter sour cream pie is your new best friend. It strikes that elusive, magical balance between the silky wobble of a custard and the dense, velvety decadence of a cheesecake.
The Secret to the Perfect Texture: Why 1/3 Cup is the Sweet Spot
Sometimes people think “more is better” with peanut butter, but 1/3 cup is actually the magic number for this specific peanut butter sour cream pie.
Because we are going for that unique custard-cheesecake hybrid, adding too much peanut butter would make the filling heavy, oily, or dense like fudge. By sticking to 1/3 cup, you let the sour cream and eggs do their job to keep the texture velvety and light. The peanut butter provides that perfect nutty essence without “stealing the show” from the creamy base. It’s all about the balance!

- Test with a toothpick, cake tester or slender knife to see if anything sticks for determining doneness.
