Applesauce: Provides natural sweetness and moisture.
Cinnamon: Enhances the warm, cozy flavor of the cake.

Step-by-Step Instructions

Prepare the Batter:

Preheat the Oven: Set the oven to 350°F (175°C). Grease a small baking dish or line it with parchment paper.
Mix the Dry Ingredients: In a medium bowl, whisk together the protein powder, almond flour, baking powder, cinnamon, and salt.
Combine the Wet Ingredients: In a separate bowl, whisk the applesauce, almond milk, egg, maple syrup, and vanilla extract until smooth.
Mix the Batter: Gradually add the dry ingredients to the wet mixture, stirring until just combined.

Create the Cinnamon Swirl:

Prepare the Swirl: In a small bowl, mix coconut sugar, cinnamon, and melted coconut oil.
Layer the Batter: Pour half of the cake batter into the prepared dish. Drizzle half of the cinnamon mixture over the batter. Repeat with the remaining batter and cinnamon mixture.
Swirl: Use a toothpick or knife to create a marbled effect by swirling the cinnamon mixture into the batter.

Bake and Serve:

Bake the Cake: Place the dish in the oven and bake for 18-20 minutes, or until a toothpick inserted in the center comes out clean.
Cool and Slice: Let the cake cool for a few minutes before slicing and serving.

Additional Tips

Use a high-quality protein powder for the best taste and texture.
Avoid overmixing the batter to keep the cake light and fluffy.
Let the cake cool before slicing to prevent crumbling.
Adjust the cinnamon swirl for a stronger or milder flavor.
Store leftovers in an airtight container to keep them fresh.

Recipe Variations

Swap Almond Flour for Oat Flour: If I want a different texture, I replace almond flour with oat flour. Oat flour gives the recipe a slightly denser, more hearty consistency and a mild, naturally sweet flavor. It also adds extra fiber, making the dish even more filling. If I don’t have store-bought oat flour, I can easily make my own by blending rolled oats into a fine powder.
Use Chocolate Protein Powder for a Unique Twist: For a richer, more indulgent flavor, I swap regular protein powder for chocolate protein powder. This deepens the chocolate taste and enhances the overall sweetness without the need for extra cocoa or sweeteners. It’s a great way to make the recipe feel more like a dessert while still keeping it high in protein. If I want an extra chocolatey boost, I sprinkle in a few cacao nibs or mini chocolate chips.
Add Chopped Nuts or Raisins for Extra Texture: To add some crunch and chewiness, I mix in chopped nuts like walnuts, pecans, or almonds. These not only provide extra texture but also bring in healthy fats and a bit of natural richness. If I want a little sweetness, I add raisins, dried cranberries, or chopped dates, which create bursts of flavor in every bite. This variation works especially well if I’m aiming for a more energy-packed snack.
Make It Dairy-Free with a Flax Egg and Plant-Based Protein Powder: For a completely dairy-free version, I substitute a regular egg with a flax egg (made by mixing 1 tablespoon of ground flaxseed with 3 tablespoons of water and letting it sit for a few minutes to thicken). I also use plant-based protein powder instead of whey-based options. This swap keeps the recipe vegan while maintaining its protein content. If I need to adjust the texture, I sometimes add a splash of almond or oat milk to keep the batter smooth.

Freezing and Storage

Freezing: To keep the slices fresh for longer, I wrap each one individually in plastic wrap to prevent freezer burn and maintain moisture. Then, I place the wrapped slices in an airtight container or a freezer-safe zip-top bag, removing as much air as possible before sealing. This method helps preserve freshness and prevents the slices from sticking together. The slices can be frozen for up to 2 months. When I’m ready to enjoy one, I simply remove it from the freezer and let it thaw at room temperature for about 30 minutes. For a quicker option, I microwave a slice in 10-15 second intervals until it’s soft and warm.
Storage: For short-term storage, I keep the slices in an airtight container at room temperature for up to 2 days. If I want to extend their freshness, I store them in the refrigerator, where they stay good for up to a week. To prevent the slices from drying out, I place a sheet of parchment paper between them or wrap them in plastic wrap before placing them in the container. Before serving, I sometimes let a refrigerated slice sit at room temperature for a few minutes or warm it slightly in the microwave for a freshly baked feel.

Special Equipment

Mixing Bowls: I use a set of mixing bowls to blend the ingredients smoothly and evenly. A medium-sized bowl is perfect for mixing the dry ingredients, while a separate bowl for wet ingredients ensures everything combines properly before incorporating them together. If I’m making multiple batches or experimenting with variations, having extra bowls on hand makes the process more efficient.
Whisk: A whisk is essential for achieving a smooth, lump-free batter. I use it to blend the wet ingredients thoroughly and to incorporate the dry ingredients without overmixing. If I want an ultra-smooth consistency, I sometimes use a hand mixer or an immersion blender for an even more refined texture.
Small Baking Dish: A well-sized baking dish ensures even cooking and the perfect thickness for the recipe. I typically use an 8×8-inch dish for balanced baking, allowing the batter to spread out evenly without becoming too thin or too thick. For best results, I lightly grease the dish or line it with parchment paper to prevent sticking and make slicing easier.
Toothpick or Knife for Creating the Swirl: If I’m making a recipe with a swirl effect, like a chocolate or nut butter swirl, I use a toothpick or the tip of a knife to gently drag through the batter, creating a beautiful marbled pattern. This technique helps distribute flavors evenly while adding a decorative touch to the final product. If I want a more defined swirl, I sometimes use the back of a spoon to create deeper streaks.
