Ingredients You Will Need
For the Cream Filling
- 2 boxes instant vanilla pudding mix
- 3 cups cold whole milk
- 1 cup sourdough discard
- 8 ounces whipped topping or whipped cream
For the Layers
- 1 box honey graham crackers or cinnamon crackers
For the Chocolate Topping
- 2 cups semi-sweet chocolate chips
- 1/2 cup unsalted butter
- 1/4 cup whole milk
- 1 teaspoon vanilla extract
- Pinch of sea salt
Step-By-Step Instructions
Step 1: Prepare the Vanilla Filling
In a large mixing bowl, combine:
- Vanilla pudding mix
- Cold milk
Whisk for about 2 minutes until thick and smooth.
Next, gently fold the sourdough discard into the pudding mixture using a spatula. Stir carefully so the filling stays smooth and creamy.
Finally, fold in the whipped topping or whipped cream. This keeps the mixture light, airy, and fluffy.
Step 2: Build the First Layer
Take a 9×13-inch glass baking dish and place a layer of graham crackers across the bottom.
Break a few crackers if needed to fill in small spaces around the edges.
Spread half of the pudding mixture evenly over the crackers.
Step 3: Add More Layers
Place another layer of graham crackers over the pudding filling.
Spread the remaining pudding mixture evenly over the second cracker layer.
Finish with one final layer of graham crackers on top.
At this point, your dessert will already look beautifully layered.
Step 4: Make the Chocolate Topping
In a microwave-safe bowl, combine:
- Chocolate chips
- Butter
- Milk
Microwave in 30-second intervals, stirring between each round until fully melted and smooth.
Add:
- Vanilla extract
- Sea salt
Stir until glossy and silky.
Pour the chocolate topping evenly over the top graham cracker layer and spread carefully to the edges.
Step 5: Chill Overnight
Cover the dish with plastic wrap and refrigerate for at least 8 hours, preferably overnight.
This is the most important step because the graham crackers need time to soften into cake-like layers.
The longer it chills, the better the texture becomes.
Serving Suggestions
Once chilled, slice into squares using a sharp knife.
Serve cold straight from the refrigerator for the best flavor and texture.
Optional toppings:
- Chocolate shavings
- Crushed nuts
- Sea salt flakes
- Fresh strawberries
- Whipped cream
Why Sourdough Discard Works So Well
Adding sourdough discard may sound unusual in a no-bake dessert, but it works beautifully.
The slight tanginess balances the sweetness of:
- Vanilla pudding
- Chocolate ganache
- Graham crackers
This creates a more sophisticated flavor instead of a dessert that tastes overly sugary.
Sourdough discard also helps reduce food waste while giving your dessert a homemade artisan touch.
Helpful Tips
Use Cold Milk
Cold milk helps the pudding thicken quickly and smoothly.
Chill Overnight
Do not rush the chilling process. Overnight chilling creates the perfect soft texture.
Use High-Quality Chocolate
Better chocolate creates a richer and smoother ganache topping.
Customize the Layers
Try adding:
- Bananas
- Strawberries
- Peanut butter drizzle
- Crushed cookies
- Toasted nuts
Storage Tips
Store covered in the refrigerator for up to 4 days.
This dessert actually tastes even better the second day because the flavors continue blending together.
It is one of the best make-ahead desserts for parties and gatherings.
