Ingredients You’ll Need

For the Cake:

  • 2 cups almond flour
  • 1/4 cup coconut flour
  • 1 tsp baking powder
  • 1/2 tsp salt
  • 1/3 cup melted butter or coconut oil
  • 1/3 cup powdered erythritol or monk fruit sweetener
  • 2 large eggs
  • 1 tsp vanilla extract
  • 1 tbsp heavy cream or unsweetened almond milk

Optional: 1/2 tsp cinnamon in the batter for extra spice

For the Streusel Topping:

  • 1/4 cup almond flour
  • 2 tbsp powdered erythritol or monk fruit
  • 1 tsp ground cinnamon
  • Pinch of salt
  • 2 tbsp melted butter or coconut oil

Optional: Crushed pecans or walnuts for added crunch and flavor


Step-by-Step Instructions

Step 1: Preheat the Oven

Preheat your oven to 325°F (160°C) . Grease an 8×8-inch square pan or mini loaf pans and line with parchment paper if desired.

Tip: Use silicone molds for even easier release and clean-up.

Step 2: Mix Dry Ingredients

In a mixing bowl, whisk together:

  • Almond flour
  • Coconut flour
  • Baking powder
  • Salt
  • Optional: Cinnamon

Mix well to evenly distribute everything.

Pro Tip: Coconut flour is highly absorbent—measure carefully and sift if possible.

Step 3: Add Wet Ingredients

To the dry mixture, add:

  • Melted butter or oil
  • Powdered sweetener
  • Eggs
  • Vanilla extract
  • Heavy cream or almond milk

Stir until smooth and slightly thick—but still scoopable.

Note: The batter should be firm but moist. Add more almond flour if too wet.

Step 4: Prepare the Streusel Topping

In a small bowl, combine:

  • Almond flour
  • Powdered sweetener
  • Cinnamon
  • Salt

Add melted butter or oil and stir until coarse crumbs form.

Fold in crushed nuts if using.

Step 5: Layer the Cake and Topping

Pour half of the cake batter into the prepared pan and spread evenly.

Sprinkle a generous layer of streusel over the top.

Drop spoonfuls of the remaining batter over the streusel and gently spread.

Top with more streusel before baking.

Step 6: Bake Until Golden

Bake at 325°F (160°C) for 30–35 minutes , or until a toothpick inserted in the center comes out mostly clean (with just a few moist crumbs).

Let cool completely before slicing.

Step 7: Serve and Enjoy!

Slice into squares or bars and enjoy warm or at room temperature.

Pair with black coffee, tea, or your morning bulletproof coffee for the ultimate treat.

Enjoy every soft, cinnamon-spiced bite of your Keto Coffee Cake !

  • Author: WAFA LI
  • Total Time: 1 hr

Description

Rich, moist, and sweet, this cake is a delightful treat!


Ingredients

🧈 6 tbsp Unsalted butter (softened)
🍬 3/4 cup Besti Monk Fruit Allulose Blend
🥚 3 large Eggs
🥛 1/4 cup Heavy cream
🍦 1/2 tbsp Vanilla extract
🌰 3 cups Wholesome Yum Blanched Almond Flour
🧂 2 tsp Baking powder
🧂 1/4 tsp Sea salt
🌰 1 1/2 cups Wholesome Yum Blanched Almond Flour (Streusel)
🍬 3/4 cup Besti Brown Monk Fruit Allulose Blend (Streusel)
🌿 1 1/2 tbsp Cinnamon (Streusel)
🧂 1/8 tsp Sea salt (Streusel)
🧈 4 tbsp Unsalted butter (melted, Streusel)
🍦 1/4 tsp Vanilla extract (Streusel)
🍬 3 tbsp Besti Powdered Monk Fruit Allulose Blend (Icing)
🥛 1 1/2 tbsp Heavy cream (Icing)


Instructions

Preheat the oven to 325°F (162°C). Grease a 9×9-inch stoneware baking dish. In a large bowl, use a hand mixer to beat together the butter and Besti until fluffy and light yellow. Beat in the eggs, cream, and vanilla. Beat in the almond flour, baking powder, and sea salt until uniform. The batter will be fairly thick. In a small bowl, stir together the almond flour, Besti Brown, cinnamon, and sea salt until uniform. In another small bowl, stir together the melted butter and vanilla. Add the melted butter mixture to the brown sugar mixture and stir until crumbly. Spread half of the coffee cake batter evenly over the baking dish. Crumble half of the streusel (about 1.5 cups) on top. Dollop tablespoonfuls of remaining batter over the streusel, then spread evenly. Crumble remaining streusel on top. Bake for about 25 minutes, until the streusel is darker golden. Tent the top with foil and bake for 20-30 more minutes, until the coffee cake is no longer jiggly and an inserted toothpick comes out clean. Whisk together the Besti Powdered and heavy cream. Allow the cake to cool for at least 20 minutes before drizzling with icing.
