Step‑by‑Step Instructions for Chocolate Birthday Cake Cookie
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While the oven heats, grab a baking skillet and grease it lightly with cooking spray or a thin layer of oil. This ensures that your Chocolate Birthday Cake Cookie will slide out smoothly after baking and develop an appealing golden hue on the edges.
Step 2: Mix Dry Ingredients
In a large mixing bowl, combine the organic all-purpose flour, Ascent 100% Native Whey Protein Blend, baking powder, baking soda, kosher salt, and both granulated monk fruit sweeteners. Use a whisk to mix them thoroughly until no clumps remain, creating a uniform dry base for your Chocolate Birthday Cake Cookie, which sets the stage for the wet ingredients to be added next.
Step 3: Add Wet Ingredients
Crack a large egg and add the egg yolk to the dry mixture, along with the vanilla extract and cacao nut butter. Using a spatula, gently mix these ingredients until the batter is smooth and cohesive. Be careful not to overmix, as this helps retain the fudgy texture that defines our delicious Chocolate Birthday Cake Cookie.
Step 4: Fold in Chocolate and Sprinkles
Once your dough is smooth, it’s time to fold in the chopped organic chocolate bar and dye-free sprinkles. Use a spatula to gently combine them without overworking the dough. The chunks of chocolate will melt slightly during baking, creating gorgeous pockets of gooeyness throughout the Chocolate Birthday Cake Cookie, while the sprinkles add a fun festive twist.
Step 5: Bake the Cookie
Spread the cookie dough evenly across the bottom of your prepared skillet, smoothing the top with your spatula. Place it in the preheated oven and bake for 25-28 minutes. You’ll know it’s done when the edges are golden brown, and the center is set but slightly soft—perfect for that heavenly gooey texture we all crave in a Chocolate Birthday Cake Cookie.
Step 6: Cool and Serve
Once baked, remove the skillet from the oven and allow the cookie to cool slightly for about 10 minutes. This resting period makes it easier to slice and serve. When you’re ready, cut into wedges and enjoy warm, allowing the rich flavors and textures of your Chocolate Birthday Cake Cookie to shine!

Chocolate Birthday Cake Cookie Recipe FAQs
What should I look for when selecting ripe ingredients?
Absolutely! When choosing ingredients like bananas or nut butters, ensure they’re fresh. Look for bananas that are ripe but not overly brown, as they’re the sweetest and blend smoothly. For nut butters, opt for those without added sugars or oils to keep it clean and nutritious.
How do I store leftover Chocolate Birthday Cake Cookie?
Very easy! Let the cookie cool completely and store it tightly covered at room temperature for up to 2 days. If you want to keep it fresh for longer, refrigerate it for up to 5 days—just ensure it’s wrapped well to maintain its deliciousness!
Can I freeze leftover portions? How?
Of course! To freeze, slice the cookie into portions and wrap each slice tightly in plastic wrap. Place them in an airtight container or freezer bag and store them for up to 2 months. When you’re ready for a treat, just pop a slice in the microwave for 15-20 seconds to enjoy that warm, gooey goodness again.
What if I overbake the cookie?
No worries! If you find that your cookie has dried out, I recommend adding a dollop of Greek yogurt or warm nut butter on top before serving. This can help add moisture back in and enhance the chocolate experience. Keep a close eye after 25 minutes of baking to catch it at just the right time!
Are there any dietary considerations for this recipe?
Absolutely! This recipe can be made gluten-free with the right flour substitute, and for a vegan option, simply swap the egg with a flax egg (1 tablespoon of ground flaxseed mixed with 2.5 tablespoons of water). Make sure to choose a plant-based protein powder for those keeping their diets animal-free.
Can I substitute the chocolate bar with something else?
Yes! If you’re not a fan of chocolate bars or prefer a lower-sugar option, feel free to use dark chocolate chips or even a fruit-based topping, like berry jam. Just ensure that whatever you use complements the overall flavor profile of your Chocolate Birthday Cake Cookie.
