Ultimate Reeses Peanut Butter Poke Cake Recipe with Easy Chocolate Ganache

This was supposed to be a simple chocolate poke cake—nothing fancy, just a quick dessert for a spontaneous dinner party.

But after poking holes and pouring that silky chocolate ganache over the top, the dessert transformed into this rich, indulgent Ultimate Reese’s Peanut Butter Poke Cake with Chocolate Ganache that I can’t stop making.

What Ingredients You Will Need

This recipe uses simple, wholesome ingredients that come together to create bold flavors and a satisfying texture without the fuss. Most items are pantry staples, and the peanut butter and chocolate really shine here.

• For the Cake Batter:
  • 1 box chocolate cake mix (about 15.25 oz / 432 g) – I prefer Ghirardelli for a richer chocolate flavor
  • 1 cup creamy peanut butter (250 g) – smooth works best for that silky texture
  • 3 large eggs, room temperature
  • 1 cup sour cream (240 ml) – adds moisture and tang
  • ½ cup vegetable oil (120 ml)
  • ¾ cup water (180 ml)
• For the Poke Filling:
  • 1 jar creamy peanut butter (about 16 oz / 454 g) – for drizzling into the holes
  • ½ cup creamy peanut butter melted (120 g) – to make it more pourable for the filling
• For the Chocolate Ganache:
  • 1 cup heavy cream (240 ml) – I always go for organic heavy cream for the best texture
  • 8 oz semi-sweet chocolate chips or chopped chocolate (225 g) – Lindt or Ghirardelli make this ganache extra smooth
  • 1 tbsp unsalted butter (14 g), softened – adds shine and richness
  • 1 tsp vanilla extract (5 ml)

If you’re feeling adventurous, you can swap the sour cream for Greek yogurt for a tangier bite, or use almond milk in place of water for a dairy twist. For a gluten-free version, try a gluten-free chocolate cake mix and double-check all other ingredients.

Equipment Needed

• 9×13-inch baking pan – a classic metal or glass pan works fine; I personally prefer glass because it heats evenly and makes cleanup easier.
• Electric mixer or stand mixer – helps get the batter smooth, but a sturdy whisk works if you’re patient.
• Mixing bowls – at least two, ideally medium and large sizes.
• Measuring cups and spoons – accuracy matters, especially for the ganache.
• Small saucepan – to warm the cream for the ganache.
• Wooden skewer or fork – for poking holes in the cake.
• Spatula – for mixing and spreading the ganache smoothly.

If you don’t have a mixer, I’ve made this cake by hand—just expect a bit more arm work. A silicone spatula is my go-to for scraping every bit of batter out of the bowl without waste. Keeping your chocolate ganache warm but not boiling is easier with a heavy-bottomed saucepan to avoid scorching.

Preparation Method

1. Preheat your oven to 350°F (175°C). Grease your 9×13-inch pan thoroughly with butter or non-stick spray, then lightly dust with cocoa powder to prevent sticking.
2. Prepare the batter: In a large bowl, combine the chocolate cake mix, creamy peanut butter, eggs, sour cream, vegetable oil, and water. Use an electric mixer on medium speed to blend everything until smooth and fully combined, about 2–3 minutes. The batter will be thick but glossy.
3. Pour the batter into your prepared pan and smooth the surface with a spatula. Tap the pan gently on the counter to release any air bubbles.
4. Bake for 35–40 minutes, or until a toothpick inserted in the center comes out with moist crumbs but not wet batter. Keep an eye toward the end so you don’t overbake—it should be moist and tender.
5. Remove from the oven and let cool for about 10 minutes. This is when things get fun—grab a wooden skewer or fork and poke holes all over the cake, roughly 1 inch apart. The holes should be deep but not go all the way through.
6. Make the peanut butter drizzle: In a small bowl, melt ½ cup of peanut butter in the microwave for 30 seconds, then stir until smooth and pourable. Drizzle this peanut butter evenly over the cake, letting it seep into the holes.
7. Prepare the chocolate ganache: Heat the heavy cream in a small saucepan over medium heat until it just begins to simmer (do not boil). Remove from heat and pour over the chopped chocolate in a heatproof bowl. Let sit for 2 minutes, then stir gently until smooth and glossy. Stir in the butter and vanilla extract until combined.
8. Pour the ganache over the cake evenly, using a spatula to smooth it out. The ganache will slowly set as the cake cools.
9. Chill the cake in the refrigerator for at least 1 hour before serving to let the flavors meld and the ganache firm up perfectly.

If the ganache starts to harden before you spread it, just give it a quick warm-up in the microwave for 10 seconds and stir again. Also, don’t skip the chilling step—it’s key for the ganache texture and flavor.

Cooking Tips & Techniques

Let me share some kitchen wisdom I picked up making this Ultimate Reese’s Peanut Butter Poke Cake with Chocolate Ganache:

• Mixing matters: When combining the peanut butter into the batter, make sure it’s at room temperature so it blends smoothly. Cold peanut butter can cause lumps, which nobody wants.
• Poking holes with purpose: Use a wooden skewer rather than a fork for more control, and don’t poke holes too close together or the cake might feel soggy. About an inch apart is just right.
• Ganache texture: Stir gently when mixing the ganache to keep it silky. Over-stirring can cause it to look dull.
• Don’t rush chilling: I’ve learned the hard way that skipping the fridge step results in a runny ganache that doesn’t set up.
• Timing tip: Bake the cake first, then prepare the ganache while it cools. This way, everything comes together smoothly without waiting around.
• Watch your oven: Oven temps vary, so start checking the cake at 35 minutes to avoid dryness.

You know, I once tried making the ganache without warming the cream first—big mistake. The chocolate never melted properly, and I ended up with lumps. Lesson learned: patience and precision make all the difference!

Variations & Adaptations

This recipe is surprisingly versatile, and I’ve played around with a few tweaks you might enjoy:

• Nut-Free Version: Swap peanut butter for sunflower seed butter to keep the creamy texture but avoid nuts.
• Salted Caramel Twist: Drizzle salted caramel sauce over the ganache before chilling for an extra layer of flavor.
• Seasonal Fruit Addition: Add sliced bananas or strawberries on top just before serving to brighten the richness.
• Dairy-Free Adaptation: Use coconut cream instead of heavy cream and a dairy-free chocolate for the ganache.
• Mini Cake Version: Make the recipe in individual ramekins or a muffin tin for portion control or party favors.

One time, I made it with a swirl of Nutella mixed into the batter alongside peanut butter—crazy good with a slightly different chocolate-nutty twist. Feel free to experiment and make this your own!

Serving & Storage Suggestions

Serve this Ultimate Reese’s Peanut Butter Poke Cake with Chocolate Ganache chilled or at room temperature. I like to slice it into generous squares and pair with a cold glass of milk or a scoop of vanilla ice cream on the side.

It’s also fantastic with coffee or a rich hot chocolate for a cozy dessert moment. For presentation, sprinkle some chopped Reese’s pieces or crushed peanuts on top for texture and extra eye appeal.

Store leftovers in an airtight container in the refrigerator for up to 4 days. The flavors actually deepen overnight, so it tastes even better the next day. If you want to freeze, wrap tightly and freeze for up to 2 months. Thaw in the fridge overnight and warm slightly before serving.

Reheating gently in the microwave for 15 seconds brings back that soft, gooey texture without melting the ganache completely.

Nutritional Information & Benefits

This cake is an indulgent treat, but it does have some nutritional perks thanks to its ingredients. The peanut butter provides heart-healthy fats and a good dose of protein, while the sour cream adds calcium. Using a boxed cake mix keeps prep simple, though you could try a whole-grain or reduced-sugar mix for a lighter version.

Per serving (approximate): 400 calories, 25g fat, 40g carbs, 7g protein. Keep in mind, it’s a dessert to enjoy in moderation, but it also satisfies cravings so well it might save you from over-snacking later!

If you have allergies, watch out for nuts, dairy, and gluten in this recipe, but the substitutions shared make it adaptable.

Frequently Asked Questions

Can I use natural peanut butter instead of creamy?

Natural peanut butter can work but tends to separate and might make the batter less smooth. If you use it, stir well before measuring and consider adding a bit more oil to keep the texture moist.

Is it possible to make this cake from scratch instead of a box mix?

Absolutely! Use your favorite homemade chocolate cake recipe and add the peanut butter as shown. Just be sure the batter isn’t too thin, or the poke holes won’t hold the filling as well.

How thick should the ganache layer be?

A thin, even layer about ¼ inch (6 mm) thick is perfect. It should coat the cake completely but not be so thick that it overwhelms the peanut butter flavor.

Can I prepare this cake a day ahead?

Yes! In fact, chilling it overnight enhances the flavors and lets the ganache set beautifully. Just cover it tightly in the fridge.

What’s the best way to reheat leftover cake?

Warm individual slices in the microwave for 15–20 seconds to bring back softness without melting the ganache completely. Avoid overheating to keep the texture just right.
