Healthy Oatmeal Chocolate Chunk Cookie Bars are an easy way to enjoy everything you love about freshly baked cookies in bar form. Packed with melted dark chocolate, these bars are thick and chewy in the center with satisfyingly crisp edges. They are made without butter, dairy-free, and refined sugar-free, making them a lighter dessert that still feels indulgent.
Ingredients needed for Oatmeal Cookie Bars
These oatmeal chocolate chunk cookie bars use simple, wholesome ingredients and are naturally dairy-free and free of refined sugar when you choose those swaps.
- Refined coconut oil: 1/2 cup, melted. Use refined coconut oil for a neutral flavor rather than virgin coconut oil, which tastes like coconut.
- Coconut sugar: 1 cup. A refined-sugar-free option with a rich, brown-sugar-like flavor.
- Egg: 1 large egg for binding and moisture.
- Vanilla extract: 2 tsp for classic cookie flavor.
- Almond milk: 2 tbsp (or other plant or dairy milk) to add a touch of moisture.
- Old-fashioned oats: 1/2 cup for texture and oat-forward flavor.
- All-purpose flour: 1/2 cup to give structure to the bars.
- Baking powder: 1/4 tsp to help the bars lift slightly.
- Salt: 1/4 tsp in the batter, plus an extra pinch to sprinkle on top.
- Dark chocolate: About 3.5 oz (roughly 1 cup chopped). Use a dark chocolate bar for rich, melty pockets of chocolate.
How to make Healthy Oatmeal Chocolate Chunk Cookie Bars
This recipe is straightforward and quick. In about 35 minutes you’ll have warm bars with gooey chocolate and a chewy oat crumb.
- Preheat the oven to 350°F (175°C).
- In a large bowl, combine the melted refined coconut oil and coconut sugar until smooth.
- Whisk the egg for about 1 minute until slightly bubbly and foamy—this helps create a shiny, crinkly top on the bars.
- Stir the whisked egg, vanilla extract, and almond milk into the sugar and oil mixture until evenly combined.
- Add the old-fashioned oats, all-purpose flour, baking powder, and salt, mixing until the dry ingredients are incorporated.
- Fold in the chopped dark chocolate so it’s distributed throughout the batter.
- Press the batter into a greased or parchment-lined 8×8-inch baking dish, smooth the top, and sprinkle with a pinch of salt. Bake for 20 minutes, until the edges are set but the center remains slightly soft.
- Allow the bars to cool completely before cutting into squares for cleaner slices and the best texture.
Tips for the best Oatmeal Cookie Bars
These quick tips will help ensure consistent results and the best texture.
- Cool before cutting: Because the bars are intentionally a bit gooey in the center, letting them cool completely gives cleaner, neater squares.
- Choose a dark chocolate bar: A dark chocolate bar chopped into chunks melts into rich pools throughout the bars—aim for a higher cacao percentage for deep chocolate flavor.
- Whisk the egg well: Whisking the egg until slightly foamy helps form a glossy, crinkly top that makes the bars look and feel more like classic cookie bars.
Additions and variations
Customize these bars to suit your tastes—here are a few ideas to try.
- Nuts: Add chopped peanuts, almonds, or walnuts for extra crunch.
- Nut butter swirl: Swirl in peanut butter, almond butter, or cashew butter before baking for a rich ribbon of flavor.
- Different chocolate: Swap dark chocolate for milk or white chocolate if you prefer a sweeter bite.
- Raisins: Turn them into oatmeal raisin bars by folding in raisins instead of chocolate.
- Cinnamon: Add a pinch or 1/2 tsp of cinnamon to the dry mix for warm spice notes.
Storing Oatmeal Cookie Bars
Store cooled bars in an airtight container at room temperature for 3–5 days. For longer keeping, refrigerate them; they will stay good in the fridge for 1–2 weeks. To enjoy a warm bar, microwave briefly before serving.
Freezing instructions
Yes—these bars freeze well. Place cooled bars in a freezer-safe container or zip-top bag and freeze for up to a couple of months. Thaw in the refrigerator or microwave an individual portion to enjoy warm chocolate pockets.
