Ingredients Breakdown

• Dark chocolate chips (2 cups): 60–70% cacao for rich flavor and firmness.
• Creamy peanut butter (1/2 cup): Adds body and silkiness; almond or cashew works too.
• Sweetened condensed milk (1 can, 14 oz): The secret to that ultra-fudge texture.
• Instant espresso powder (2–3 tsp): Dissolves instantly and intensifies chocolate.
• Cocoa powder (2 tbsp, unsweetened): Deepens flavor and prevents overly sweet fudge.
• Vanilla extract (1 tsp): Rounds out the mocha vibe.
• Fine sea salt (1/2 tsp): Balances sweetness and boosts flavor.
• Crushed chocolate wafers or graham crackers (1 cup): Optional for subtle crunch.
• Coconut oil or butter (1 tbsp): Helps with a glossy, clean slice.
• Toppings (optional): Cacao nibs, flaky sea salt, mini chips, or toasted nuts.

How to Make It – Instructions

1. Prep the pan: Line an 8×8-inch pan with parchment, leaving overhang for easy lift-out. Lightly grease the parchment.
2. Bloom the espresso: In a small bowl, mix espresso powder with 1 tablespoon hot water until dissolved. Set aside.
3. Melt the base: In a medium saucepan over low heat, add chocolate chips, sweetened condensed milk, peanut butter, and coconut oil.

   Stir constantly until smooth—don’t let it simmer.

4. Flavor boost: Remove from heat; stir in cocoa powder, vanilla, sea salt, and the espresso mixture. Taste a tiny bit (careful, hot) and adjust espresso if you want more punch.
5. Add texture (optional): Fold in crushed wafers or grahams for gentle crunch. Don’t overmix or it gets crumbly.
6. Pan it: Spread the mixture into the prepared pan.

   Smooth the top with an offset spatula.

7. Top it off: Sprinkle flaky salt, cacao nibs, or nuts. Press lightly so they stick.
8. Chill: Refrigerate for 2–3 hours until firm. If you’re impatient (same), 45 minutes in the freezer works, but keep an eye on it.
9. Slice: Lift out by the parchment.

   Warm a sharp knife under hot water, dry it, and cut into 16–25 squares.

10. Serve: Best slightly chilled so they hold that perfect fudgy bite.

Storage Tips

• Fridge: Store in an airtight container for up to 10 days. Separate layers with parchment.
• Freezer: Freeze up to 2 months. Thaw in the fridge 30–45 minutes for ideal texture.
• Room temp: Short periods (2–4 hours) are fine in a cool room, but they soften fast.

Why This is Good for You

• Dark chocolate: Packed with antioxidants and mood-friendly compounds—thanks, flavonoids.
• Espresso: Gentle caffeine boost for focus and… happiness?

  Feels like it.

• Nut butter: Provides healthy fats and a bit of protein to keep you satisfied.
• Built-in portion control: Small squares pack big flavor, so a little goes a long way (in theory).

Common Mistakes to Avoid

• Overheating the chocolate: Low and slow wins; scorched chocolate turns grainy and sad.
• Skipping the salt: A pinch unlocks flavor. Don’t fear it.
• Using watery add-ins: Fresh fruit or wet toppings can seize the chocolate. Stick to dry toppings.
• Cutting too soon: Warm fudge smears.

  Chill fully for clean, brag-worthy squares.

• Too much espresso: Bitter city. Start with 2 tsp and scale up IMO.

Alternatives

• Dairy-free: Use coconut condensed milk and dairy-free chips; swap butter with coconut oil.
• Nut-free: Use sunflower seed butter or tahini for a subtle, sophisticated edge.
• Sweetness tweaks: Prefer less sweet? Use 70–85% chocolate and add 1–2 tbsp extra peanut butter.
• Texture flips: Add toasted hazelnuts, pretzel bits, or cacao nibs for crunch.
• Flavor twists: Add 1/2 tsp cinnamon, a pinch of chili powder, or orange zest for café-level flair.

FAQ

Can I use brewed coffee instead of espresso powder?

Yes, but keep it concentrated.

Use 1 tablespoon very strong brewed coffee and reduce other liquid to avoid soft fudge. Espresso powder dissolves cleaner and tastes bolder, FYI.

Why is my fudge oily or separated?

It was likely overheated. Next time, melt on low heat and stir gently.

If it breaks, whisk in a splash of warm milk or more condensed milk to bring it back.

How do I make thicker bars?

Use a 9×5-inch loaf pan for tall, bakery-style slabs. Chill longer and cut smaller—these are rich.

Can I leave out the peanut butter?

Absolutely. Replace with equal parts almond, cashew, or sunflower seed butter.

Skipping entirely will make it firmer and slightly less creamy.

Is this safe for kids with caffeine sensitivity?

Use decaf espresso powder or cut the espresso in half. The flavor stays mocha-ish without the buzz.
