Soften the cream cheese: If it’s cold, microwave in short 5–10 second bursts until easily stirrable.
This prevents lumps in your oats.
Make the cheesecake base: In a medium bowl, whisk cream cheese, Greek yogurt, honey or maple, vanilla, almond extract (if using), lemon zest, and a pinch of salt until smooth.
Add the dry ingredients: Stir in the oats and chia seeds. Mix well to fully coat the oats in the creamy mixture.
Smash some berries: Lightly mash half the blackberries with a fork to release their juices. Fold them into the oat mixture for that streaky, berry-swirl look.
Adjust the texture: Pour in the milk and stir until everything is evenly combined.
The mix should look a little loose; it will thicken overnight.
Jar it up: Transfer to a 12–16 ounce jar or airtight container. Top with the remaining blackberries. If using frozen berries, add them now—no thawing needed.
Chill: Cover and refrigerate for at least 4 hours, preferably overnight, until thick and creamy.
Finish and serve: In the morning, give the oats a good stir.
If they’re too thick, splash in a little more milk. Add crushed graham crackers or granola right before eating for a cheesecake “crust” crunch.
