    Ingredients

    As usual, you'll find the complete recipe card, including ingredient amounts and instructions, at the bottom of this post! Keep on reading for more details, or jump straight to the recipe.

    • Oats (rolled or instant) — Form the hearty base of the oatmeal layer and provide a wholesome texture.
    • Oat flour (or ground oats) — Either oat flour or roughly ground oats work well in this recipe
    • Maple or agave syrup — You can easily substitute it with any other granulated sweetener of your choice.
    • Coconut oil — Make sure it’s deodorized/refined so it doesn’t leave a coconutty taste.
    • Baking powder — Adds lightness and helps achieve a tender texture in the oatmeal layer.
    • Salt — Enhances the flavors.
    • Dairy-free chocolate (60-70% cocoa) — I used 60% cocoa, which provided just the right amount of sweetness for me. However, any chocolate between 60% and 70% cocoa content works perfectly for this recipe.
    • Peanut butter — Adds creaminess and nutty flavor to the fudge layer.

    How to Make these Gluten-free & Vegan Oatmeal Fudge Bars

    Preheat the oven and prepare the pan: Preheat your oven to 350ºF (176ºC). Line an 8x8 baking pan with parchment paper to prevent sticking.

    Prepare the oatmeal mixture: In a mixing bowl, combine the oats, oat flour, maple or agave syrup, coconut oil, baking powder, and salt. Mix until you achieve a paste-like consistency.

    Preparation of the oatmeal mixture

    Prepare the fudge mixture: In a separate bowl, melt the dairy-free chocolate. Once melted, stir in the peanut butter until well combined.

    Preparation of the fudge mixture

    Assemble the oat layer: Spread about two-thirds of the oat layer mixture evenly onto the bottom of the lined baking dish.

    Assembling of the oat layer

    Add the fudge layer: Pour the fudge layer mixture over the oat layer in the baking dish, spreading it out evenly.

    Top with the remaining oat mixture: Crumble the remaining oat layer mixture over the fudge layer.

    Pouring of the fudge layer to the oatmeal layer

    Bake: Place the baking dish in the preheated oven and bake for 28-30 minutes, or until the oatmeal topping is lightly golden.

    Cool down: Remove the baking dish from the oven and allow it to cool completely. Once cooled, transfer the dish to the refrigerator and chill for at least 3-4 hours, or until the chocolate has hardened.

    Storage & Freezing

    Store leftover oatmeal bars in an airtight container in the refrigerator for up to 10 days.
    For longer storage, wrap individual bars tightly in parchment paper or plastic wrap, place in a ziploc bag and freeze for up to 3-4 months.

    Top Tips for these Oatmeal Bars

    1. Line the Pan Properly: When lining your baking pan with parchment paper, make sure to leave some overhang on the sides. This will make it easier to lift the bars out of the pan once they're cooled and set.
    2. Cool Completely: Allow the bars to cool completely in the pan before transferring them to the refrigerator. This helps them set properly and prevents them from becoming too soft or crumbly.
    3. Chill for Optimal Texture: While it may be tempting to dig in right away, chilling the bars in the refrigerator for the recommended time ensures that the fudge layer sets properly and develops its signature creamy texture.
    4. Sharp Knife for Clean Cuts: When cutting the bars into squares, use a sharp knife and wipe it clean between cuts for neat and uniform portions.
    5. Store Properly: To keep the bars fresh and delicious, store them in an airtight container in the refrigerator.

    How long do these bars last?

    Stored properly in the fridge, they'll stay fresh for up to 10 days.

    Can I freeze these bars?

    Yes, you can freeze them for up to 3-4 months. Wrap them tightly to prevent freezer burn.

    Yes, they're made with gluten-free oats and oat flour.
