Ingredients You’ll Need
You won’t believe how basic this ingredient list is—no complicated substitutes, no fancy flours. Every element here adds something important, from contributing to the luscious crumb to amping up the flavor, and even the pop of color. Let’s take a closer look:
- Zucchini: Provides epic moisture, keeps the crumb tender, and sneaks in a veggie that completely disappears into the batter (the secret star!)
- Creamy peanut butter: Swirls into the cake for nutty richness and helps keep everything flour-free.
- Granulated sugar: Adds essential sweetness and balances the deep chocolate notes.
- Brown sugar: Brings a touch of molasses flavor and even more moistness to the cake.
- Oil: Makes every bite extra tender and rich (don’t skip it!)
- Eggs: Bind everything together and add lift for a lovely texture.
- Vanilla: Rounds out the flavors and brings warmth to every slice.
- Cocoa powder: Delivers that seriously intense chocolate flavor we all crave.
- Baking soda & baking powder: The combo guarantees a perfectly risen, just-dense-enough crumb.
- Salt: Enhances every flavor and balances the sweetness beautifully.
- Chocolate chips (optional): For extra bursts of molten chocolate in every bite—totally your call, but highly recommended.
How to Make ini Cake with Peanut Butter (Flour-Free)
Step 1: Prep Your Pan and Oven
Start by setting your oven to 350°F (175°C). That way it’s ready to go once your batter is mixed. Grease a 9-inch cake pan and if you want to make life easy when unmolding, line the base with parchment paper. This keeps your ini Cake with Peanut Butter (Flour-Free) in perfect shape!
Step 2: Mix Wet Ingredients with Zucchini
In a large bowl, combine the squeezed-dry zucchini with creamy peanut butter, both sugars, oil, eggs, and vanilla. Use a sturdy whisk or an electric mixer and really mix until the batter is smooth and completely emulsified—no streaks left behind. The zucchini melts in, adding all that moisture with zero veggie flavor.
Step 3: Stir In Dry Ingredients
Add in the cocoa powder, baking soda, baking powder, and salt directly into your wet mixture. Gently stir or fold until you get a thick, even batter with no dry pockets. Don’t be alarmed by its dark richness; the cocoa will seem intense at this stage, but it mellows once baked.
Step 4: Fold In Chocolate Chips (Optional)
If you’re after truly molten bites or just want that extra chocolate drama, fold in your chocolate chips gently. This step is totally flexible—skip it or go wild, depending on your mood!
Step 5: Decorate and Bake
Pour the batter into your prepared pan and then smooth the top. For that gorgeous peanut butter marbling, drop a few generous spoonfuls of peanut butter on top and use a butter knife to create elegant swirls. Slide the pan into the oven and bake for 35 to 40 minutes. You’ll know it’s done when the center is set and a toothpick comes out with moist crumbs (not totally clean, for the perfect fudgy texture).
Step 6: Cool and Slice
Let the finished ini Cake with Peanut Butter (Flour-Free) rest in the pan for at least 15 minutes, then carefully lift it out using the parchment. Once fully cooled, slice into wedges and get ready for chocolate heaven.
How to Serve ini Cake with Peanut Butter (Flour-Free)

Garnishes
Dust the top with a little extra cocoa powder for drama or sprinkle on chopped peanuts for crunch. If you want to go over-the-top, a drizzle of warm peanut butter or even a dollop of softly whipped cream will make each slice of ini Cake with Peanut Butter (Flour-Free) unforgettable.
Side Dishes
Pair a wedge with a scoop of vanilla ice cream or cool Greek yogurt for contrast, or serve public-style with fresh raspberries or sliced bananas to balance the richness. A hot mug of coffee or a big glass of cold milk is always a classic next to this decadent cake.
Creative Ways to Present
Make it party-ready by cutting the ini Cake with Peanut Butter (Flour-Free) into mini squares for a brownie-like dessert platter, or serve with tiny skewers and dip options (think melted chocolate or caramel). For birthdays or celebrations, stack two cakes with peanut butter “frosting” sandwiched in between for a flour-free layer cake no one will forget.
Make Ahead and Storage
Storing Leftovers
Wrap leftover slices tightly in plastic wrap or pop them into an airtight container. They’ll stay ultra moist and delicious on the counter for up to two days, or refrigerate if your kitchen runs warm. Honestly, this cake tastes even fudgier the next day!
Freezing
For longer storage, slice the ini Cake with Peanut Butter (Flour-Free), wrap the pieces well, and freeze for up to two months. Thaw overnight in the fridge or just let a slice sit at room temperature for about 30 minutes when that chocolate craving strikes.
Reheating
If you love a gooey, melty bite, pop a slice in the microwave for ten to fifteen seconds. This brings the chocolate chips back to life and makes the peanut butter topping soft and swoon-worthy again.
FAQs
Can I use almond butter or another nut butter instead of peanut butter?
Absolutely! While peanut butter is classic for this recipe, almond butter or even sunflower seed butter will give you a different but equally delicious flavor and still keep the ini Cake with Peanut Butter (Flour-Free) nice and moist.
Will I taste the zucchini in the cake?
Not at all! The zucchini melts right in, leaving you with an incredibly tender, fudgy cake with no veggie flavor—just chocolate and peanut butter goodness.
Can I make this recipe vegan?
You can try swapping the eggs for flax eggs (1 tablespoon ground flaxseed mixed with 3 tablespoons water per egg), but the texture may be a bit denser. Make sure to choose a vegan peanut butter and check that your chocolate chips are dairy-free.
What’s the best way to grate and squeeze zucchini?
Use the fine holes of a box grater, then gather the grated zucchini in a clean towel and twist to squeeze out as much water as possible. This prevents a soggy cake and keeps the crumb just right.
Can I make cupcakes with this batter?
Yes! Line a muffin tin and fill cups three-quarters full. Baking time will be shorter, usually around 20-25 minutes. You’ll get irresistibly fudgy individual treats—just watch for doneness earlier.
