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 !
