Chocolate Peanut Butter Tart Recipe

There’s an odd satisfaction in the play of textures in this tart: the crisp crust, the smooth, almost silky chocolate layer, and that sticky, salty peanut butter swirl on top. I like to think of it as a little chaos in every bite, a messy harmony of flavors that feels honest and unpretentious. It’s not about perfection; it’s about that moment when everything comes together just right, even if a little imperfect.

A lot of recipes focus on neatness, but I find it’s the little quirks that make this tart memorable. Maybe a smear of peanut butter that runs over the side or a crack in the chocolate that reveals that glossy, fudgy interior. It’s a reminder that sometimes, the best desserts are the ones that embrace their flaws, inviting you to dig in with a spoon and enjoy every bit of the messy, rich goodness.

Personal story behind the tart

Ingredient insights and tweaks

• Dark chocolate: I prefer a 70% bar for richness. It melts smooth and not overly sweet.
• Peanut butter: Natural, chunky peanut butter adds texture and flavor. Stir well to reincorporate oil.
• Graham crackers: For the crust, they give a buttery crunch. Swap with digestive biscuits if needed.
• Butter: Use unsalted for control over salt. It gives the crust structure and flavor.
• Sea salt: Flaky salt on top enhances sweetness and adds a delightful crunch.

Spotlight on key ingredients

Dark chocolate:

• It’s rich, slightly bitter, and melts into a glossy layer that’s not overly sweet.
• Peanut butter: Adds salty, nutty depth. Its oil helps create that luscious marbling when swirled.

Graham crackers:

• Their sweet, toasty flavor forms the perfect base. Use gluten-free if needed.
• They crisp up beautifully and add a satisfying crunch.

Substitutions to customize your tart

• Dairy-Free: Swap regular butter for coconut oil or vegan butter for a dairy-free crust.
• Vegan Chocolate: Use dairy-free dark chocolate for the topping, it melts just as smoothly.
• Gluten-Free: Replace graham crackers with crushed gluten-free biscuits or almond meal.
• Sweetener: Use honey or maple syrup in the crust for a slightly different flavor.
• Peanut Butter: Almond or cashew butter can be a good substitute, though the flavor will differ.

Equipment & Tools

• Tart pan: To shape and bake the crust
• Mixing bowls: For melting chocolate and mixing ingredients

7. Chill the tart in the fridge for at least 2 hours or until set.
8. Before serving, sprinkle flaky sea salt on top and slice with a hot, sharp knife.
9. Let it sit at room temperature for 15 minutes before cutting for easier slicing.
