No-Bake Peanut Butter Chocolate-Chip Oat Bars with Pumpkin Seeds

These chewy no-bake oat bars are the kind of snack that makes an afternoon easier. Peanut butter and maple syrup hold rolled oats together, while dairy-free chocolate chips and crunchy pumpkin seeds add just enough sweetness and texture. There is no oven to preheat—simply mix, press, chill, and slice.

• ¾ cup (190 g) smooth peanut butter, well stirred
• ½ cup (120 ml) maple syrup

How to make no-bake peanut butter oat bars

1. Prepare the pan

Line an 8-inch (20 cm) square pan with parchment paper, leaving some paper hanging over two opposite sides. The overhang makes the chilled bars much easier to lift out and cut.

2. Mix the dry ingredients

In a large bowl, combine the rolled oats, oat flour, pumpkin seeds, salt, and about ⅓ cup of the chocolate chips. Stir to distribute everything evenly.

3. Stir together the peanut butter mixture

In a separate medium bowl, stir the peanut butter, maple syrup, and vanilla until smooth and glossy. If the peanut butter is very stiff, let it come to room temperature before mixing; a pourable, well-stirred peanut butter blends most easily.

4. Combine and press firmly

Pour the peanut butter mixture over the oats. Stir with a sturdy spatula until no dry pockets remain; the mixture should be thick and sticky. Tip it into the lined pan. Using the back of a spoon or the flat bottom of a measuring cup, press it down very firmly into an even layer, especially at the corners.

5. Finish with chocolate chips

Scatter the remaining chocolate chips over the surface and press them lightly into the bars so they stick after chilling.

6. Chill, cut, and enjoy

Refrigerate for at least 1 hour, or until firm enough to slice cleanly. Lift the slab out using the parchment overhang, place it on a cutting board, and cut into 12 rectangular bars (three rows by four columns). Keep refrigerated until ready to eat.

Practical tips for bars that hold together

• Press harder than you think. Thoroughly compacting the mixture is the most important step for neat, portable bars.
• Use oat flour for structure. If you have only rolled oats, pulse a heaped ½ cup in a blender until powdery, then measure out ½ cup of the resulting flour.
• Adjust the texture. If the mixture seems dry and won't clump when squeezed, mix in 1–2 teaspoons more peanut butter or maple syrup. If it feels too loose, add 1–2 tablespoons more oats.
• Double-check the chips. Not all dark chocolate chips are dairy-free, so read the package if you're cooking vegan.
• Allow enough chilling time. These bars are softer than baked granola bars and slice best cold.

Simple swaps

For a peanut-free option, replace the peanut butter with well-stirred sunflower seed butter; the flavor and firmness may change slightly. Chopped dried cranberries or raisins can replace some of the chocolate chips. If gluten-free bars are important to you, choose certified gluten-free oats and check your other packaged ingredients.

Storage

Store the bars in an airtight container in the refrigerator for up to 7 days, separating layers with parchment if needed. For longer storage, freeze them in a sealed freezer-safe container for up to 2 months. Let a frozen bar thaw in the refrigerator before eating. Because they soften when warm, pack them with a cold pack for trips or lunchboxes.

Make them your own

A batch is easy to prepare ahead for snacks, lunchbox treats, or a quick bite between meals. Rolled oats, peanut butter, and pumpkin seeds also work in plenty of other simple vegan dishes, so they're useful additions to your vegan shopping list.
