Ingredients
The success of these overnight jars hinges on a few key players. Weetabix gives a sturdy, absorbent base that soaks up the sauce without turning mushy. Hazelnut spread (or Nutella) delivers the signature chocolate‑hazelnut flavor, while dark cocoa powder deepens the richness. A splash of milk creates a pourable consistency, and a touch of honey balances bitterness with natural sweetness. Finally, optional toppings add texture and visual interest.
Base Layer
- 4 slices Weetabix
- 150 ml milk (dairy or plant‑based)
Chocolate Hazelnut Mixture
- 3 tbsp hazelnut spread (Nutella or similar)
- 1 tbsp unsweetened cocoa powder
- 1 tbsp honey or maple syrup
- ¼ tsp vanilla extract
- Pinch of sea salt
Toppings & Extras
- 2 tbsp toasted hazelnut pieces
- Fresh berries (optional)
- Optional drizzle of extra hazelnut spread
Together these ingredients create a balanced breakfast jar. The milk‑softened Weetabix absorbs the chocolate‑hazelnut sauce, preventing sogginess while delivering a pleasant chew. Hazelnut spread and cocoa bring depth and a luxurious mouthfeel, and the honey lifts the flavor just enough to keep it kid‑friendly. The final sprinkle of toasted nuts adds a satisfying crunch that contrasts the creamy interior.
Step-by-Step Instructions

Preparing the Weetabix Base
Break each Weetabix slice into bite‑size pieces and place them in a large bowl. Warm the milk slightly (about 40 °C) so it melds easily, then pour over the crumbs. Stir gently until the pieces are evenly coated but not soggy; they should retain a slight crunch. This step ensures the base will soak up the sauce without turning mushy.
Mixing the Chocolate Hazelnut Sauce
- Combine wet ingredients. In a microwave‑safe bowl, whisk together hazelnut spread, honey, and vanilla extract until smooth. Microwave for 20‑30 seconds, just enough to loosen the mixture.
- Incorporate dry cocoa. Sift cocoa powder and a pinch of sea salt over the melted spread. Whisk vigorously until no lumps remain; the sauce should be glossy and pourable.
- Adjust consistency. If the sauce feels too thick, stir in a splash of extra milk (about 1‑2 tbsp). The final texture should coat the back of a spoon without pooling.
Assembling the Overnight Jars
Take four 250 ml mason jars and start with a layer of the milk‑soaked Weetabix at the bottom (about ⅓ of the jar). Spoon a generous drizzle of the chocolate‑hazelnut sauce over the cereal, then repeat the cereal‑sauce layering until the jar is nearly full, leaving room for toppings.
Finish each jar with a sprinkle of toasted hazelnut pieces and, if desired, a handful of fresh berries. Seal the jars tightly and place them in the refrigerator.
Chilling & Serving
Allow the jars to chill overnight (or at least 6 hours). During this time the Weetabix will fully absorb the sauce, creating a creamy, pudding‑like texture. In the morning, give each jar a quick stir to distribute any settled sauce, add an extra drizzle of hazelnut spread if you like, and enjoy straight from the jar or pour into a bowl.
Tips & Tricks
Perfecting the Recipe
Use room‑temperature milk. Warmed milk integrates with the Weetabix faster, preventing uneven soaking and a soggy bottom.
Do not over‑mix the sauce. Over‑whisking can introduce air, making the sauce too thin once it cools.
Toast hazelnuts briefly. A 3‑minute toast in a dry skillet brings out a nutty aroma and adds crunch.
Flavor Enhancements
Add a pinch of espresso powder to the chocolate sauce for deeper cocoa notes, or stir in a teaspoon of almond butter for extra nutty richness. A splash of orange zest brightens the flavor profile without overpowering the chocolate.
Common Mistakes to Avoid
Avoid using cold milk; it will leave the Weetabix partially dry. Also, don’t skip the chilling step—without enough time, the cereal won’t fully absorb the sauce, resulting in a grainy texture.
Pro Tips
Batch‑prepare for the week. Assemble a full set of jars on Sunday; they keep well in the fridge for up to five days.
Use a small whisk. A mini whisk incorporates the cocoa powder without forming lumps, saving time.
Layer strategically. Finish with the sauce on top, then toppings; this prevents the nuts from becoming soggy.
Serve slightly chilled. Let jars sit at room temperature for 5 minutes before eating to enhance aroma.
Variations
Ingredient Swaps
Replace Weetabix with toasted granola for extra crunch, or use rolled oats for a softer texture. Swap hazelnut spread for almond or cashew butter if you prefer a different nut flavor. For a dairy‑free version, use oat milk and a plant‑based chocolate spread.
Dietary Adjustments
For a low‑sugar option, substitute honey with a few drops of stevia or monk fruit sweetener. Gluten‑free eaters can use gluten‑free crisped rice cereal instead of Weetabix. To make it keto‑friendly, replace the cereal with crushed pork rinds and use a sugar‑free chocolate hazelnut spread.
Serving Suggestions
Serve the jars alongside a glass of cold almond milk or a cup of strong black coffee for a balanced breakfast. For brunch, pair with a light citrus salad to cut through the richness. A dollop of Greek yogurt on top adds protein and a tangy contrast.
Storage Info
Leftover Storage
Cool the jars completely before sealing. Store them in airtight containers or keep the lids tightly closed in the refrigerator. They stay fresh for up to five days. For longer keeping, transfer the mixture (without toppings) to a freezer‑safe bag and freeze for up to three months; add fresh toppings after thawing.
Reheating Instructions
These jars are best enjoyed cold, but if you prefer warmth, microwave a single jar (lid removed) on medium power for 45‑60 seconds, stirring halfway. Alternatively, place the jar in a 300°F oven for 8‑10 minutes, uncovered, until the sauce bubbles gently.
