Butter, softened – Enhances the creamy swirl with added richness.
Powdered Swerve – For sweetness that blends seamlessly into the cream cheese mix.

How to Make Peanut Butter Earthquake Cake

Preheat and Prepare: Start by preheating your oven to 325ºF and greasing a 9×13 glass or ceramic baking pan. This ensures your cake won’t stick, making for an easy release once it’s baked.
Mix the Cake Base: In a large bowl, whisk together the almond flour, Swerve Sweetener, cocoa powder, baking powder, and salt. Stir in the eggs, melted butter, water, and vanilla extract until the mixture is smooth and well combined. Spread this batter evenly into the prepared pan.
Prepare the Cream Cheese Swirl: In another large bowl, beat the cream cheese, peanut butter, and softened butter together until the mixture is creamy and smooth. Gradually beat in the powdered Swerve, then add the almond milk and vanilla extract, mixing until everything is well blended.
Create the Swirl: Dollop spoonfuls of the cream cheese mixture over the cake batter. Use a knife to swirl these dollops into the batter, creating a beautiful marbled effect.
Add Toppings: Sprinkle the dark chocolate chips and chopped salted peanuts evenly over the top of the cake mixture. Bake for 35 to 45 minutes, or until the edges are set and the center is soft and slightly jiggly.
Finish with Peanut Butter Cups: While the cake is still warm, sprinkle the chopped sugar-free peanut butter cups on top, allowing them to melt slightly into the cake. Let it cool before serving, and enjoy the delightful flavors!

Optional: Serve with a dollop of whipped cream for an extra indulgent touch.

Helpful Tricks for Peanut Butter Earthquake Cake

Ingredient Care: Always measure your almond flour and sweeteners accurately—too much can change the cake’s texture and flavor.

Mixing Technique: When blending the cream cheese with peanut butter, allow both to be at room temperature for a smoother consistency in your swirl.

Swirling Smart: Use a butter knife to gently create swirls instead of mixing completely. This keeps the distinct layers of your Peanut Butter Earthquake Cake intact.

Cooling Time: Don’t rush to cut into the cake while it’s warm; letting it cool completely ensures cleaner slices and that the flavors meld beautifully.

Bake to Perfection: Keep an eye on baking times. Test with a toothpick—if it comes out with moist crumbs, it’s done; too dry means overbaked!

Peanut Butter Earthquake Cake Recipe FAQs

What type of almond flour should I use?
I recommend using blanched almond flour for this recipe. It has a finer texture and will create a lighter cake. Avoid almond meal, as it has a coarser consistency, which may not yield the desired fluffiness in your Peanut Butter Earthquake Cake.

How long can I store Peanut Butter Earthquake Cake?
At room temperature, you can store your cake in an airtight container for up to 3 days. If you prefer it fresh from the fridge, wrap it well and keep it there for up to one week, ensuring each piece remains moist and delicious.

Can I freeze Peanut Butter Earthquake Cake?
Absolutely! For optimal freezing, cut the cake into individual slices. Wrap each slice tightly in plastic wrap, followed by aluminum foil, and store in the freezer for up to 3 months. This method preserves the flavors and prevents freezer burn.

What should I do if my cake seems too wet after baking?
If your cake remains jiggly in the center after the baking time, it may need a few extra minutes in the oven. Just keep an eye on it! The edges should be set while the center is slightly moist. If it’s too wet overall, you might have added too much liquid—next time, gently fold the wet ingredients into the dry ones to avoid overmixing.

Are there any dietary considerations for this recipe?
Yes! This Peanut Butter Earthquake Cake is a fantastic option for those avoiding refined sugars, as we use Swerve Sweetener. However, keep in mind the natural peanut butter and cream cheese may contain allergens, so check labels if you’re serving guests with allergies! It’s best to opt for sugar-free versions of your ingredients if you’re watching sugar intake.

How do I make the perfect swirl in my Peanut Butter Earthquake Cake?
For an impressive swirl, dollop the cream cheese mixture in spoonfuls over the batter. Instead of mixing completely, use a butter knife to gently create swirls through the batter; aim for a balance of marbled design while keeping the layers distinct. This will ensure that each piece has that decadent creaminess without losing the overall chocolate base.
