This Keto Coffee Cake is made without almond flour or coconut flour, is low in carbs, and would make for the perfect accompaniment alongside your morning cup of coffee. The recipe requires just 15 minutes of prep time and the cake can be made and served in just 1 hour.


Coffee Cake:

Crumble Topping:


  1. Coffee Cake: Line a 8×8-inch baking pan with parchment paper.
  2. In a mixing bowl, stir together ground sunflower seed meal, protein powder, baking powder, cinnamon, and salt.
  3. In a separate clean mixing bowl, using an electric mixer, mix together eggs, monk fruit sweetener, melted butter, yogurt, and vanilla extract until pale and light in color, about 2 minutes. Add dry ingredients to bowl of wet ingredients and mix again with electric mixer until all ingredients are well-combined. Pour mixture into prepared baking pan and, using a rubber spatula, smooth top into even layer. Set pan aside and allow oven to start preaheating to 350 degrees Fahrenheit (175 degrees Celcius).
  4. Crumble Topping: In a food processor or high-speed blender, pulse sunflower seeds and sesame seeds until just floured, leaving some seeds still in-tact and chunky. Transfer floured seeds to a clean mixing bowl, add remaining ingredients and mix using a rubber spatula until ingredients are incorporated; the mixture will be lumpy and thick.
  5. Spoon crumble mixture atop cake batter in baking pan and, using a rubber spatula, distribute the crumble mixture onto top of batter. Using a knife or toothpick, carefully slightly mix crumble into some of the batter to add additional texture to the cake.
  6. Transfer baking pan to oven and bake uncovered for 25 minutes before loosely covering with foil to finish cooking for additional 15-20 minutes (this is to avoid the crumble from over-browning), or until a skewer can be inserted and come out clean.
  7. Final Steps: Remove pan from oven and allow cake to cool per slicing and serving. Note that the cake will continue to firm up while it cools outside of the oven so be sure to not over-bake.

Recipe Notes:

What Is Ground Sunflower Seed Meal: Ground sunflower seed meal is, quite literally, ground-up sunflower seeds. I buy mine pre-ground from Amazon, but you can make your own by grinding up raw sunflower seeds in a blender or food processor until it turns into a flour. Be sure to not over-blend it as the sunflower seeds will go from being a flour consistency to the consistency of sunflower seed butter.

Ground Sunflower Seed Meal Substitution: You can make ground sunflower seed meal by pulsing raw sunflower seeds in a blender or food processor until they turn into a flour. If you can eat nuts, you should be able to substitute in almond flour at a 1:1 ratio substitution.

Unflavored Whey Protein Powder Substitution: Egg white powder should work here at a 1:1 substitution. The easiest place to find this will be Amazon, though some grocery stores do carry it. If you are going to order online, I would suggest just ordering unflavored whey protein powder.

Gluten-Free Baking Powder Substitution: You can replace the gluten-free baking powder in this recipe by making your own at home using baking soda and cream of tartar. For the 2 tsp of baking powder this recipe calls for, you will need to use 1/2 tsp baking soda and 1 tsp cream of tartar. Cream of tartar can typically be found at your grocery store with the spices. This substitution will make your recipe grain-free.

Where Monk Fruit Sweetener Can Be Purchased: I purchase my golden monk fruit sweetener from Lakanto’s website and have it delivered. If you also want to do this, you can use discount code REALBALANCED at checkout for 20% OFF your order. If you’d rather find and purchase monk fruit sweetener in-store, many grocery stores, especially specialty stores and Costco, carry Lakanto products.

Golden Monk Fruit Sweetener Substitution: Classic Monk Fruit Sweetener, Swerve, or erythritol can be used here at a 1:1 substitution ratio. Note that if you make any substitutions to the Golden Monk Fruit Sweetener, the flavor of the cake may be slightly different than the original recipe intended.

Full-Fat Greek Yogurt Substitution: Sour cream should work here. Substitute in for yogurt at a 1:1 ratio.

Net Carbs: The recipe yields 16 servings, and each serving contains 3.4 grams of net carbs. One serving is equivalent to one slice of coffee cake.

Storage: Store the baked coffee cake in an airtight container in the refrigerator for up to 4 days. Note that this will lead to the cake becoming a little denser so, if you prefer, before eating leftovers, you can heat it up in the microwave for 15-20 seconds to soften it.
