Equipment

  • 9x9 inch (23x23 cm) metal cake pan
  • Parchment Paper
  • Medium Bowl
  • Large Bowl
  • Small Bowl
  • Whisk
  • Toothpick

Ingredients
  

For the Cinnamon Swirl

  • 2/3 cup finely ground almond flour
  • 1/3 cup packed sugar-free brown sugar substitute
  • 1 1/2 teaspoons ground cinnamon
  • 1/4 teaspoon kosher salt
  • 1/4 cup melted butter
  • 1/3 cup chopped pecans (optional)

For the Cake Batter

  • 2 cups finely ground almond flour
  • 3/4 cup sugar-free granulated sweetener
  • 1 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon kosher salt
  • 3 large eggs lightly beaten
  • 1/2 cup plain Greek yogurt or sour cream
  • 2 teaspoons vanilla extract

For the Optional Icing

  • 1/2 cup sugar-free powdered sweetener
  • 2 tablespoons heavy cream
  • 1/2 teaspoon vanilla extract
  • Water as needed for thinning

Instructions
 

  • Get Ready: Preheat your oven to 350°F (175°C). Lightly grease a 9x9 inch (23x23 cm) metal cake pan with butter or cooking spray. For easy cake removal, create a parchment paper "sling" by lining the pan with two overlapping strips that extend over the edges.
  • Make the Swirl: In a medium bowl, simply mix all the cinnamon swirl ingredients together until you have a thick mixture. Set this aside for a moment.
  • Mix Dry Cake Ingredients: Grab a large bowl and whisk together the almond flour, granulated sweetener, baking powder, baking soda, and salt.
  • Add Wet Cake Ingredients: Now, stir in the beaten eggs, Greek yogurt (or sour cream), and vanilla extract into your dry mixture. Mix just until everything is combined and smooth.
  • Assemble the Cake: Pour your lovely cake batter into the prepared pan, spreading it out evenly.
  • Create the Swirl: Spoon dollops of your thick cinnamon mixture evenly over the cake batter. Don't worry about perfection; as it bakes, the cake batter will rise around these dollops, creating a beautiful swirled pattern.
  • Bake to Perfection: Pop the cake into your preheated oven and bake for 30-35 minutes. It's done when it's golden brown and a toothpick inserted into the center comes out clean.
  • Cool Down: Let the cake cool in the pan for 15-30 minutes before gently lifting it out using your parchment paper sling.
  • Whip up the Icing (Optional): While the cake is cooling, whisk together the powdered sweetener, heavy cream, and vanilla extract in a small bowl. Gradually add water, ½ tablespoon at a time, until the icing is thin enough to drizzle smoothly.
  • Drizzle & Enjoy: Once the cake is fully cooled, drizzle the sweet icing generously over the top. Cut into 12 squares and serve!

Notes

This easy keto coffee cake is a fantastic low-carb option for breakfast or a healthy treat. The cinnamon swirl adds a rich flavor, and the optional icing provides an extra touch of sweetness.
