- 3 tbsp honey (60 g)
- 60 ml heavy cream
- 195 g roasted, salted peanuts
- For the cake:
- 85 g unsalted butter, softened
- 280 g all-purpose flour
- 2 tsp baking powder
- ½ tsp salt
- 200 g sugar
- 1 large egg, room temperature
- 2 tsp vanilla extract
- 180 ml whole milk
- 1 tbsp instant coffee dissolved in 2 tbsp hot water
Substitution Options
If you’re missing an ingredient or want to tweak the recipe, here are some ideas:
- Use almond butter instead of peanut butter for a nuttier flavor.
- Swap heavy cream with coconut cream for a dairy-free option.
- Replace instant coffee with espresso powder for a stronger coffee kick.

Preparation Steps
Step 1: Prep Your Pan
Start by greasing a 23 cm springform pan and lining the bottom with parchment paper. This ensures your Coffee Peanut Cake will slide out effortlessly after baking. Preheat your oven to 180°C (350°F) to get it nice and toasty. Pro tip: Always prep your pan before mixing your ingredients—it’s a small step that saves you from last-minute stress!
Step 2: Caramelize Those Peanuts
In a saucepan over medium heat, melt the butter with sugar, honey, and cream. Stir constantly until the mixture bubbles, then let it simmer for 3 minutes. Remove from heat and stir in the peanuts. The aroma of caramelizing sugar is absolutely heavenly! Let this cool slightly while you work on the cake batter.
Step 3: Mix the Dry Ingredients
In a bowl, sift together the flour, baking powder, and salt. Sifting not only removes lumps but also aerates the flour, giving your cake a lighter texture. Chef’s tip: Don’t skip the sifting step—it makes a noticeable difference!
Step 4: Cream the Butter and Sugar
In another bowl, beat the softened butter and sugar until light and fluffy. Add the egg and vanilla, mixing until smooth. Pour in the coffee mixture and blend well. The coffee will deepen the color of the batter and infuse it with a rich aroma. Pro tip: Use room-temperature eggs for easier blending.
Step 5: Combine Wet and Dry Ingredients
Add half of the dry ingredients to the wet mixture, followed by the milk. Finish with the remaining flour, mixing just until combined. Overmixing can lead to a dense cake, so stop as soon as everything comes together. Pour the batter into your prepared pan and smooth the top.
Step 6: Add the Peanut Topping
Spoon the caramelized peanuts evenly over the batter, avoiding the edges to prevent burning. Pop the pan into the oven and bake for 50–55 minutes, or until a toothpick inserted into the center comes out clean. The cake will puff up beautifully, filling your kitchen with the most amazing scent.
Step 7: Cool and Serve
Let the cake cool in the pan for 10 minutes before releasing the springform sides. Run a knife around the edges if needed. Slice and serve with a dollop of whipped cream or a scoop of vanilla ice cream for extra indulgence.

Chef’s Secret
To take your Coffee Peanut Cake to the next level, sprinkle a pinch of flaky sea salt over the caramelized peanuts before baking. The salt enhances the sweetness and adds a gourmet touch.
Fun Fact About the Ingredients
Peanuts aren’t actually nuts—they’re legumes! They belong to the same family as beans and lentils. Despite this, their rich, nutty flavor makes them a perfect pairing for sweet treats like this cake.
Necessary Equipment
- Springform pan (23 cm)
- Mixing bowls
- Electric mixer or whisk
- Saucepan
- Spatula
- Parchment paper
Storage Tips
Store your Coffee Peanut Cake in an airtight container at room temperature for up to 3 days. If you live in a warm climate, refrigerate it to keep the caramelized topping from softening too much. To reheat, pop a slice in the microwave for 10–15 seconds to bring back its gooey goodness.
If you need to store leftovers for longer, wrap individual slices in plastic wrap and freeze them. They’ll stay fresh for up to 2 months. Simply thaw at room temperature when ready to enjoy.
Pro tip: Label your freezer bags with the date so you don’t forget how long they’ve been stored.
Tips and Advice
- Make sure your butter is truly softened for easy creaming.
- Don’t rush the caramelization process—low and slow is the way to go.
- Use fresh baking powder for the best rise.
- Let the cake cool completely before slicing for cleaner cuts.
Presentation Ideas
- Garnish with a dusting of powdered sugar for a touch of elegance.
- Serve with a drizzle of caramel sauce for extra decadence.
- Add a sprig of mint for a pop of color.
Healthier Alternatives
Here are six ways to lighten up your Coffee Peanut Cake:
- Low-Fat Version: Substitute half the butter with Greek yogurt.
- Reduced Sugar: Cut the sugar by 25% and use a sugar substitute like stevia.
- Vegan Option: Replace eggs with flax eggs and use plant-based milk.
- Gluten-Free: Swap all-purpose flour with almond flour or a gluten-free blend.
- Lower-Calorie Peanuts: Use unsalted peanuts and reduce the amount of honey.
- No Cream: Replace heavy cream with coconut milk for a lighter topping.
Common Mistakes to Avoid
Mistake 1: Overmixing the Batter
Overmixing leads to a dense, tough cake. Mix just until the ingredients are combined. Pro tip: Stop stirring as soon as you no longer see streaks of flour.
Mistake 2: Skipping the Sifting Step
Sifting aerates the flour, making your cake lighter. Don’t skip it—it’s worth the extra minute!
Mistake 3: Burning the Peanut Topping
The caramelized peanuts can burn easily if placed too close to the edges of the pan. Keep them toward the center for even baking.
