Ingredients

Contains: milk, peanut, tree nuts (auto-detected from the ingredients and method; we can miss things, so check labels)

Directions

Method written by CompKitchen from the ingredient list. Not the original author's method, not kitchen-tested.

  1. Line an 8-inch (20 cm) square pan with parchment paper, leaving overhang on two sides to lift the squares out later.

  2. In a large bowl, combine the oats, chia seeds and half of the chopped hazelnuts, stirring to mix evenly.

  3. In a small saucepan over low heat, melt the coconut oil with the peanut butter and honey, stirring until smooth, about 2 minutes.

  4. Pour the warm peanut butter mixture over the oat mixture and stir until every piece is evenly coated.

  5. Press the mixture firmly and evenly into the prepared pan using the back of a spatula or your hands.

  6. Melt 1 cup of the chocolate chips in a heatproof bowl over barely simmering water or in the microwave in 30-second bursts, stirring until smooth.

  7. Spread the melted chocolate evenly over the oat base, then sprinkle with the remaining hazelnuts and any extra chocolate chips for topping, pressing them in lightly.

  8. Refrigerate for about 1 hour until firm, then lift out using the parchment and cut into 12 squares.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

Flavor stand-ins for the chia

How well each one fits the dish's main ingredients (oats, milk, hazelnut, peanut, butter, honey, coconut):

  1. Cinnamonbetter flavor fit
  2. Gingerabout as good a flavor fit
  3. Chiathe original

Fit is the average pairing score against oats, milk, hazelnut, peanut, butter, honey, coconut. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
