Step 1: Prepare the Graham Cracker Layer (Optional but Recommended)

If you want that authentic pie crust experience, start by crushing graham crackers into fine crumbs. Place 2-3 full graham cracker sheets in a sealed plastic bag and crush them with a rolling pin, or pulse them in a food processor. For extra richness, mix the crumbs with 1 tablespoon of melted butter or coconut oil. This creates a more cohesive, pie-crust-like layer at the bottom of your jars.

Step 2: Mix the Oat Base

In a medium mixing bowl, combine the rolled oats, milk, Greek yogurt, fresh lime juice, lime zest, honey (or maple syrup), vanilla extract, and a pinch of salt. Whisk everything together until well combined and the yogurt is fully incorporated with no lumps. If you’re using chia seeds, add them now and stir thoroughly. The mixture will look quite liquid at this stage, but don’t worry—the oats and chia seeds will absorb the liquid overnight and create a thick, creamy consistency.

Step 3: Layer Your Jars

If you prepared the graham cracker mixture, divide it evenly between 2 mason jars or airtight containers, pressing it lightly into the bottom to create a “crust” layer. Pour the oat mixture over the graham cracker layer, dividing it evenly between the jars. Leave a little space at the top for toppings in the morning.

Step 4: Refrigerate Overnight

Seal the jars tightly with lids and place them in the refrigerator. Let them chill for at least 8 hours or overnight. This resting time is crucial—it allows the oats to soften completely and absorb all those delicious lime flavors. The chia seeds (if using) will also swell and create a pudding-like texture. You can prepare these up to 5 days in advance.

Step 5: Add Toppings and Serve

In the morning, give your oats a quick stir. The consistency should be thick and creamy, similar to pudding. If they’re too thick for your liking, add a splash of milk to loosen them up. Top each jar with a dollop of whipped cream, a sprinkle of fresh lime zest, extra graham cracker crumbs, and any other toppings you love. Enjoy cold straight from the fridge, or let them sit at room temperature for 10-15 minutes if you prefer less chill.
