- 1¼ cups sugar
- 2½ teaspoons baking powder
- 1 teaspoon salt

How to Make these Chocolate Peanut Butter Tandy Kakes
Step 1: Preheat Your Oven
Get your oven nice and hot at 375°F while you gather all your ingredients.
Nothing worse than being ready to bake and realizing your oven is still cold, right?
Step 2: Prepare the Cake Batter
Sift together 1¾ cups cake flour, 1¼ cups sugar, 2½ teaspoons baking powder, and 1 teaspoon salt in a large bowl.
Mix in ⅓ cup softened unsalted butter and ⅔ cup of milk until the batter becomes smooth and velvety.
Step 3: Finish the Batter and Bake
Add 1 beaten egg, 1 teaspoon vanilla, and the remaining milk to the batter, mixing until just combined.
Pour this lovely mixture into a greased 9×13 pan and bake for about 30 minutes, or until a toothpick comes out clean.
Step 4: Cool and Chill the Cake
Let the cake cool completely at room temperature before popping it in the refrigerator.
This cooling process is essential, folks—skip it and you’ll end up with a melty mess when you try to add the peanut butter layer.
Step 5: Add the Peanut Butter Layer
Once chilled, spread a generous layer of creamy peanut butter over the entire cake surface.
Return it to the refrigerator until the peanut butter firms up, which might take 30-45 minutes.
Step 6: Create the Chocolate Ganache
Bring 1 cup heavy cream just to a boil in a saucepan.
Pour this hot cream over 16 ounces of semi-sweet chocolate chips in a heat-safe bowl, then whisk until perfectly smooth and glossy.
For the best results, use a premium stand mixer to achieve that perfect silky-smooth ganache consistency without arm fatigue.
Step 7: Finish with Chocolate Layer
Pour the still-warm ganache over the now-firm peanut butter layer, spreading it evenly with an offset spatula.
Immediately return the cake to the refrigerator to let the chocolate set completely.
Step 8: Slice and Serve
For those picture-perfect slices, make sure each layer is thoroughly chilled before cutting.
Using a warm, clean knife between cuts helps achieve those crisp, clean edges that make these treats look as good as they taste.
What to Serve with Chocolate Peanut Butter Tandy Kakes
These rich, decadent treats are perfect for afternoon snacks or dessert, but they need the right accompaniments to really shine. A scoop of vanilla bean ice cream alongside a slice creates that perfect hot-and-cold contrast we all crave.
For coffee lovers, a strong espresso or cappuccino cuts through the sweetness beautifully.
If you’re serving these at a gathering, consider adding fresh berries on the side—raspberries or strawberries provide a tart counterpoint to the chocolate and peanut butter richness.
A glass of cold milk (dairy or almond) is practically mandatory for the full nostalgic experience.
And for a truly indulgent touch, drizzle a little warm caramel sauce over the top just before serving. The layers of flavor will make everyone swoon.
Chocolate Peanut Butter Tandy Kakes Substitutions and Variations
• Flour Options: Swap cake flour with all-purpose flour plus 2 tablespoons cornstarch for each cup.
For gluten-free versions, try a cup-for-cup gluten-free baking mix.
• Dairy Alternatives: Replace milk with almond, oat, or coconut milk.
Use plant-based butter and coconut cream instead of heavy cream for dairy-free ganache.
• Peanut Butter Swaps: Can’t do peanuts?
Almond, cashew, or sunflower seed butter work beautifully for those with allergies.
• Flavor Twists: Add ½ teaspoon cinnamon to the cake batter for warmth.
Mix mini chocolate chips into the peanut butter layer, or swirl in raspberry jam for a PB&J vibe.
- Fancy Toppings: Sprinkle sea salt, chopped peanuts, or crushed pretzels over the ganache while still wet for texture and visual appeal.
- Healthier Version: Reduce sugar to 1 cup and use dark chocolate (70%+) for the ganache to cut sweetness.
Leftovers and Storage for these Chocolate Peanut Butter Tandy Kakes
These decadent treats actually get better after a day in the fridge, when the flavors have had time to meld together.
Store leftovers in an airtight container in the refrigerator for up to one week, placing parchment paper between layers to prevent sticking.
For longer storage, these bars freeze beautifully for up to 3 months.
Wrap individual portions in plastic, then foil, before freezing. Thaw in the refrigerator overnight—never at room temperature, which can make the chocolate bloom and the peanut butter soften too quickly.
To serve chilled leftovers, let them sit at room temperature for 10-15 minutes to soften slightly.
This brings out the flavors and prevents the cake from being too firm when you bite into it.
Final Thoughts
These Chocolate Peanut Butter Tandy Kakes capture the magic of nostalgic baking with three perfect layers—soft vanilla cake, creamy peanut butter, and rich chocolate ganache.

They’re ideal for holiday cookie platters, weekend baking projects with kids, or when you need a special homemade gift that shows more thought than store-bought treats.
