Step‑by‑Step Instructions for Decadent Cookie Butter Cake
Step 1: Prepare Baking Dish
Preheat your oven to 350°F (175°C). While the oven heats, take a 9×13 inch baking dish and generously grease it with butter or cooking spray to ensure easy cake release later. This initial step is crucial to achieving a perfect, golden-brown crust for your Decadent Cookie Butter Cake.
Step 2: Mix Dry Ingredients
In a large mixing bowl, whisk together 2 cups of cake flour, 1 cup of crushed Biscoff cookies, 1 teaspoon of ground cinnamon, 2 teaspoons of baking powder, and ½ teaspoon of kosher salt. Ensure the mixture is well-combined and free of lumps. The dry ingredients will provide structure and flavor to the cake, so take your time with this step for the best results.
Step 3: Beat Wet Ingredients
In another bowl, beat 1 cup of granulated sugar with 6 egg yolks until the mixture turns pale and creamy—about 4-5 minutes. Gradually mix in 1 teaspoon of vanilla extract and ½ cup of heavy cream until well blended. This wet mixture will add richness and moisture to your Decadent Cookie Butter Cake, ensuring a delightful texture.
Step 4: Combine Ingredients
Gently fold the dry mixture into the wet ingredients, mixing until just combined. Next, in a separate bowl, beat 6 egg whites until stiff peaks form. Carefully fold the whipped egg whites into the batter. This technique helps achieve a light and airy texture in your cookie butter cake, so treat the batter with care during this step.
Step 5: Bake the Cake
Pour the batter into your prepared baking dish, spreading it out evenly with a spatula. Place the dish in the preheated oven and bake for 15-20 minutes or until a toothpick inserted in the center comes out clean. The cake should be lightly golden, and a fragrant aroma will fill your kitchen as it bakes.
Step 6: Make Milk Mixture
While the cake is baking, prepare the milk mixture by whisking together 1 cup of heavy cream, 1 cup of sweetened condensed milk, and 1 cup of evaporated milk in a medium bowl. Melt ½ cup of cookie butter slightly and mix it into the milk until smooth. This rich mixture is what makes your cake a Decadent Cookie Butter Cake, soaking into the cake for incredible flavor.
Step 7: Soak the Cake
Once the cake is finished baking, remove it from the oven and use a toothpick or skewer to poke holes all over the top. Carefully pour the milk mixture over the entire cake, allowing it to soak in. Let the cake cool at room temperature for about 30 minutes before transferring it to the refrigerator. The soaking process is key for achieving that luscious tres leches texture.
Step 8: Chill
Cover the cake with plastic wrap and refrigerate for at least 4 hours, or preferably overnight. Chilling allows the flavors to meld and intensify, ensuring that every bite of your Decadent Cookie Butter Cake is immensely flavorful and moist.
Step 9: Prepare Topping
When ready to serve, whip 1 cup of heavy cream with 2 tablespoons of confectioners’ sugar and a sprinkle of cinnamon until you reach soft peaks. This creamy topping will add richness to your cake. Spread it evenly over the chilled cake and don’t forget to reserve some crushed Biscoff cookies for an irresistible garnish.
Step 10: Serve
Finally, garnish your Decadent Cookie Butter Cake with the reserved crushed Biscoff cookies for texture and a sprinkle of ground cinnamon if desired. Cut into squares and serve chilled. Each slice is a creamy, moist delight that will surely impress your family and friends!
