Ingredients

  

• 1 3/4 cups THM Baking Blend
• 1/2 cup granulated erythritol or allulose (or your preferred THM-friendly sweetener)
• 1/4 cup brown sugar substitute (like a brown erythritol blend), divided
• 2 tsp baking powder
• 1/2 tsp baking soda
• 1/2 tsp fine sea salt
• 1 tsp ground cinnamon (plus 1 tsp more for the swirl)
• 3 large eggs, room temperature
• 1/2 cup unsweetened almond milk (or another low-carb milk)
• 1/2 cup plain Greek yogurt or sour cream
• 1/3 cup melted coconut oil or butter, cooled slightly
• 2 tsp vanilla extract
• Optional streusel: 1/3 cup THM Baking Blend, 2 tbsp butter, 2 tbsp brown sugar substitute, 1/2 tsp cinnamon, pinch of salt
• Optional glaze: 1/4 cup powdered erythritol, 1–2 tbsp almond milk, 1/4 tsp vanilla

Method

 

1. Preheat your oven to 350°F (175°C).

   Grease an 8×8-inch pan or line it with parchment for easy lifting.

2. In a medium bowl, whisk together the THM Baking Blend, granulated sweetener, baking powder, baking soda, salt, and 1 tsp cinnamon.
3. In a separate large bowl, whisk the eggs, almond milk, Greek yogurt, melted oil or butter, and vanilla until smooth.
4. Add the dry ingredients to the wet ingredients and stir gently until just combined. The batter should be thick but spreadable. If it looks too stiff, add 1–2 tbsp more almond milk.
5. Make the cinnamon swirl by mixing 1 tsp cinnamon with 2 tbsp brown sugar substitute.

   Set aside.

6. Spread half the batter into the prepared pan. Sprinkle the cinnamon swirl mixture evenly over the batter. Top with the remaining batter and gently smooth the surface.
7. For the streusel (optional but highly recommended), combine THM Baking Blend, butter, brown sugar substitute, cinnamon, and a pinch of salt with a fork until crumbly.

   Scatter over the top.

8. Bake for 28–34 minutes, or until a toothpick inserted into the center comes out clean or with a few crumbs. Do not overbake.
9. Cool in the pan for at least 20 minutes. If using glaze, whisk the ingredients until smooth and drizzle over the cooled cake.
10. Slice and serve warm or at room temperature.

    Enjoy with coffee, tea, or a splash of unsweetened almond milk.

Why This Recipe Works

This coffee cake uses THM Baking Blend, which gives you a fluffy, cake-like crumb without traditional flour.

The blend keeps the net carbs lower while adding fiber and protein for better balance.

A cinnamon “sugar” swirl and a simple crumb topping deliver the classic coffee cake flavor and texture. Using erythritol or a similar sweetener keeps the cake sweet but not cloying.

Greek yogurt or sour cream gives the cake moisture and a tender crumb, so it feels indulgent while still staying light. The recipe also comes together quickly in one bowl, so it’s easy enough for weekdays and reliable for guests.

What You’ll Need

How to Store

Store the coffee cake in an airtight container at room temperature for up to 2 days. After that, move it to the fridge for another 3–4 days of freshness.

It freezes well. Wrap individual slices in plastic, then place them in a freezer bag or container.

Freeze for up to 2 months. Thaw at room temperature or warm in the microwave for 15–20 seconds.

Health Benefits

• Lower in carbs: THM Baking Blend keeps net carbs in check while still delivering a cake-like texture.
• Higher in protein and fiber: Helps with satiety and steady energy compared to traditional flour-based cakes.
• No refined sugar: Using erythritol, allulose, or a THM-approved blend supports blood sugar balance.
• Healthy fats: Coconut oil or butter adds richness and helps keep you full longer.
• Customizable for dietary needs: Easy to make gluten-free and low-glycemic as written.

What Not to Do

• Don’t overmix the batter. It can make the cake dense. Mix until the dry streaks disappear.
• Don’t overbake. Pull it out as soon as a toothpick comes out with a few moist crumbs.
• Don’t skip room-temperature eggs. Cold eggs can cause the batter to seize and bake unevenly.
• Don’t use regular sugar. It changes the carb count and sweetness balance.
• Don’t pack the baking blend. Lightly scoop and level to avoid a dry cake.

Alternatives

• Dairy-free: Use coconut yogurt instead of Greek yogurt and coconut oil instead of butter.
• Different sweeteners: Allulose makes a softer, moister crumb; erythritol gives more structure.

  Adjust to taste.

• Flavor twists: Add 1/2 tsp almond extract, or fold in 1/3 cup chopped pecans or sugar-free chocolate chips.
• Fruit swirl: Swirl in 1/3 cup finely chopped, low-glycemic berries (like raspberries) for a tart contrast.
• Glaze swap: Use a cream cheese glaze: 2 oz softened cream cheese, 2 tbsp powdered sweetener, splash of almond milk, and vanilla.

FAQ

What is THM Baking Blend, and can I substitute it?

THM Baking Blend is a low-carb, high-fiber mix designed for Trim Healthy Mama recipes. It typically combines ingredients like oat fiber, coconut flour, and nut flours. You can experiment with a homemade blend, but textures vary, so results may change.

If substituting almond flour alone, the cake will be heavier and may need extra binding and moisture.

Is this recipe THM S or E?

This coffee cake is generally treated as a THM S due to the fats used (butter or coconut oil) and the low-carb baking blend. It pairs well with coffee, eggs, or a handful of berries for a satisfying breakfast or snack.

Can I make this egg-free?

You can try three flax “eggs” (1 tbsp ground flax + 3 tbsp water per egg, set for 5 minutes). Expect a denser texture, but it can still be tasty.

Add an extra tablespoon or two of almond milk if the batter seems too thick.

Why did my cake turn out dry?

It’s usually from overbaking or packing too much baking blend into the cup. Measure lightly and start checking the cake at 28 minutes. If your oven runs hot, reduce the temperature slightly or tent the cake with foil near the end.

Can I use xylitol?

Yes, xylitol works well, but it can be toxic to pets, so handle with care.

Also note that xylitol doesn’t crystallize like erythritol, which can produce a slightly softer crumb.

Do I need the streusel and glaze?

No, the cake is delicious without them. The streusel adds texture and a bakery-style finish, while the glaze adds sweetness and shine. Choose one, both, or skip them for a simpler, lighter version.

How do I get a stronger cinnamon flavor?

Increase the cinnamon by 1/2–1 tsp in both the batter and swirl.

You can also add a pinch of nutmeg or cardamom for a warm, cozy boost.
