No-Bake Peanut Butter Bars Recipe

Imagine rich peanut butter folded into a silky chocolate ganache. These no-bake peanut butter bars deliver that classic combination in an easy, gluten-free and dairy-free treat.

I have a serious sweet tooth, so I try to make treats that feel indulgent but use simple, wholesome ingredients. Store-bought bars can be overly sweet or dry, so I developed this recipe to be soft, creamy, and just the right amount of sweet.

These bars are no-bake and require only six pantry-friendly ingredients. They slice cleanly yet melt in your mouth, making them perfect for snacks, lunchboxes, or a quick dessert.

The peanut butter base holds together nicely without becoming hard. A thin layer of chocolate-peanut ganache adds creaminess and a glossy finish without overpowering the peanut butter. These bars are naturally gluten-free, and they can be dairy-free if you choose dairy-free chocolate and coconut oil.

Ingredients and Substitutes

Peanut Butter Base

Peanut butter, unsalted (1/2 cup) — Use almond butter, cashew butter, or sunflower seed butter if you prefer a different flavor or need a nut-free option.

Coconut flour (1/2 cup) — Coconut flour absorbs liquid and gives structure. You can substitute almond flour or oat flour, but texture and moisture may change; adjust the amount slightly if needed.

Maple syrup (1/4 cup) — For alternate sweeteners use honey, agave, or a liquid sugar-free sweetener for a lower-sugar version.

Ganache

Dark chocolate chips (1/2 cup) — Semi-sweet chips or chopped dark chocolate work well. Choose a dairy-free chocolate to keep the bars dairy-free.

Peanut butter (2 tbsp) — This adds silkiness to the ganache. Substitute with almond butter if desired.

Coconut oil (1 tbsp) — Gives ganache a glossy finish and helps it set. Swap with melted butter or neutral oil if not avoiding dairy.

How to Make No-Bake Peanut Butter Bars

Step 1. Line a loaf pan (I use a 9×4-inch pan) with parchment paper so you can lift the bars out easily.

In a medium bowl, combine the peanut butter, coconut flour, and maple syrup. Mix until a thick, pliable dough forms.

Step 2. Press the dough evenly into the prepared loaf pan. Use the back of a spoon or a spatula to pack and level it so the entire base is covered.

Chill the base in the freezer while you prepare the ganache so it firms up and holds its shape.

Step 3. Combine the chocolate chips, 2 tablespoons peanut butter, and 1 tablespoon coconut oil in a microwave-safe bowl. Heat in 20–30 second bursts, stirring between each burst, until the mixture is smooth and fully combined.

Step 4. Remove the peanut butter base from the freezer and pour the ganache over it. Spread the chocolate evenly with a spatula.

Return the pan to the freezer for 10–20 minutes until the ganache sets.

Step 5. Lift the set slab from the pan and slice into 8 bars. Optionally sprinkle a pinch of flaky sea salt over the chocolate for contrast and serve chilled or at room temperature.

My Tips & Tricks

1. Let the ganache cool briefly: Allow the ganache to sit 2–3 minutes after melting before pouring it over the base. This prevents the peanut butter layer from softening and helps create clean layers.
2. Get clean slices: Use a sharp knife warmed under hot water and wiped dry between cuts for neat, professional-looking bars.
