Star Created with Sketch. 5/5 - 123 Ratings PRINT Prep Time 15 minutes Cook Time 35 minutes Serving Yield 16 servings Blueberries are already low in carbs, so it's only fitting to highlight them in the sweet, juicy, caramelized topping that crowns this keto blueberry upside-down cake. Whether you use fresh or frozen, the berries will inevitably form a glaze for the moist, gluten-free crumb to soak up, turning every piece into a slice of pure blueberry bliss. By: All Day I Dream About Food Ingredients For the topping: 1/4 cup Swerve Brown or other brown sugar substitute 1/4 cup (1/2 stick) unsalted butter, melted 1 1/4 cups blueberries (fresh or frozen) For the cake: 1 3/4 cups almond flour 1/2 cup Swerve Granular or other granulated sweetener 1/3 cup coconut flour 1/4 cup whey protein powder (or egg white protein powder) 2 teaspoons baking powder 1/4 teaspoon salt 3 large Pete and Gerry’s Organic Eggs 6 tablespoons unsalted butter, melted and slightly cooled 1/2 cup water 1 teaspoon vanilla extract Lightly sweetened whipped cream (optional) Nutritional Information Serv.

Directions To make the topping: Step 1 Preheat oven to 325F and grease a 9” x 9" square baking pan. Step 2 In a small bowl, whisk together the brown sugar substitute and melted butter until well combined. Spread over the bottom of the prepared pan. Sprinkle with the blueberries and set aside. To make the cake: Step 1 In a large bowl, whisk together the almond flour, granular sweetener, coconut flour, protein powder, baking powder, and salt. Stir in the eggs, melted butter, water, and vanilla extract until well combined. Step 2 Spread the batter over the blueberry topping as evenly as possible. Bake 30-40 minutes, until the edges are nicely browned and the center is firm to the touch. Remove and let cool 10 minutes, then place a serving platter over the baking pan and invert the cake. Immediately remove pan to avoid any sticking. Step 3 Let cake cool completely before cutting into squares. Serve with lightly sweetened whipped cream, if desired.

Reply Page 1 Created with Sketch. Erica January 28, 2021 What kind of protein powder do you use in this recipe? Vanilla or plain or? Reply Page 1 Created with Sketch. 1 Reply [email protected] January 29, 2021 Great question Erica. We typically use plain but a vanilla protein powder would work just fine as well. Just note that some protein powders can be on the sweeter side so, depending on your preference, you may choose to slightly reduce the amount of sweetener used in addition. Can't wait to hear if you give this a try! Reply Page 1 Created with Sketch. Alison September 15, 2020 I found it a bit too sweet, so incorporated the blueberries into the cake. Delicious! Great cake recipe. Reply Page 1 Created with Sketch. 1 Reply [email protected] September 15, 2020 Hi Alison, thanks for the awesome feedback! We are happy to hear you enjoyed this recipe and were even able to adjust it to your liking. Reply Page 1 Created with Sketch. Gail W September 09, 2020 This was delicious! I do like the idea of adding lemon flavor, and I will do that next time. I made it in a pie plate and cut into 8 slices, so it had twice the carbs, but I made room for them so I could splurge. To reheat, I put butter on top and cooked in microwave for one minute - came out perfectly. Reply Page 1 Created with Sketch. 1 Reply [email protected] September 10, 2020 We're so glad you loved this cake as much as we do, Gail. It's definitely a delicious way to use some of those fresh berries during blueberry season. Reply Page 1 Created with Sketch. Penny J walchli September 07, 2020 I agree, I would use lemon extract if you have it. Lemon extract or zest and blueberries, are mentioned in many dessert recipes. I tasted the batter and the lemon extract made it more distinct for the flavor. I did use protein powder with collagen (I had Vital Proteins which had 18 grams of protein and 20 grams of collagen for the ingredients, plus it was grass fed and pasture raised). Plus I only had a 8x8 glass pan available. I set the timer for 30 minutes and will keep an eye on it. It is in the oven now. I will let everyone know how it turned out.

It came out just fine, and I ended up cooking it for 50-55 minutes. Used toothpick to test when it was done. Hope this helps!!!

Reply Page 1 Created with Sketch. 1 Reply [email protected] August 26, 2020 Hey Virginia, Although we have not tried this recipe without the whey protein powder, it doesn't mean you can't. Of course with any baking recipe, leaving out an ingrediant will change the end result, and the "doneness" of the cake. Additionally, the cake may not rise as much. Reply Page 1 Created with Sketch.

Of course you could use all-purpose flour but then you couldn't consider the recipe keto. Reply Page 1 Created with Sketch. [email protected] August 19, 2020 Hi Tracy, so sorry we have so many keto recipes that include nuts. We'll certainly take this into consideration and see what we can do about that.

Glenn June 08, 2020 blueberry Reply Page 1 Created with Sketch. Marie Woods June 02, 2020 I just made the cake and I found it very thick so I added about a quarter cup of cream. I hope I didn't ruin it. Do you have any idea what the carbs are. Reply Page 1 Created with Sketch. 1 Reply [email protected] June 03, 2020 Hi Marie, We are happy to hear you took this recipe for a spin. The batter is typically a little thicker than a traditional cake batter, but thinking the extra cream you added shouldn't alter the final product too much. How did do in your view? Was it just as tasty as we remember it being? Macros per serving are as follows: 6g carbs (excluding erythritol sweetener), 13g fat, 5g protein, 3g fiber. Further nutrition information can be found below the recipe ingredients list. We hope this helps and look forward to hearing how you enjoyed your cake! Reply Page 1 Created with Sketch. 1 Reply Marie Woods July 28, 2020 I found the blueberry part kind of dry, it was tasty but dry. This time I doubled the blueberry part and I hope it tastes good also. Reply Page 1 Created with Sketch. 2 Replies Marie Woods July 29, 2020 Delicious, doubling the blueberry part was juicy and certainly not dry. The only thing is I didn't cook it long enough so the middle of the cake batter was not all cooked, still tasted good. I'll correct that the next time.

I have read in other recipes to just add that amount in additional almond flour. I feel it is easy to substitute for protein powder. I’m with you, those of us in “non” professional kitchens don’t have all these supplies and substitutions are appreciated 😀. Reply Page 1 Created with Sketch.

Jodie April 19, 2020 What can I use instead of Almond flour. Allergic to tree nuts Reply Page 1 Created with Sketch. 2 Replies Erica B April 21, 2020 Hi Jodie, sunflower seed flour is the best substitute for almond flour because of its similar composition. The recipe writer, Carolyn of All Day I Dream About Food, recommends it regularly. Add a tablespoon of lemon juice or vinegar to the cake to offset the chlorophyll in the sunflower seeds, which can turn a harmless shade of green during baking otherwise. Other non-nut flours, like coconut flour, would require re-working the recipe to accommodate their different textures. Reply Page 1 Created with Sketch. Deneé@peteandgerrys April 20, 2020 We've only tested this recipe with almond flour, so unfortunately we can't promise any results using a different flour. We found this helpful guide for substituting flours in keto recipes here: https://www.spiceography.com/almond-flour-substitute/. We hope this helps, and happy baking!

Reply Page 1 Created with Sketch. 1 Reply [email protected] January 29, 2021 Hi Bobbie, we'd recommend either using a whey, casein, or egg white protein powder in this recipe to ensure the proper texture and composition in this recipe. Arrowroot is better used as a thickening agent, whereas the protein powder serves some structural purposes in this recipe. Hope this helps and can't wait to hear if you give this a try!

Reply Page 1 Created with Sketch. 1 Reply Erica B April 17, 2020 Protein powder is in the recipe because it helps form the structure of the cake like gluten does in traditional wheat-based recipes.
