Each thick wedge of this stovetop protein cake delivers 28 grams of protein and stays under 400 calories — substantial numbers for a dessert that tastes like warm banana bread crossed with a peanut butter cookie. The protein comes from three whole eggs, two egg whites, and blended cottage cheese, creating a structure that's custardy in the center and golden on the outside. Combined with oat flour and mashed banana, it holds together beautifully without any refined flour or added sugar.

The flavor profile leans into the classic American combination of peanut butter, ripe banana, and warm cinnamon. The cottage cheese disappears entirely once blended, contributing only creaminess and a subtle tang that keeps the sweetness balanced. A thin layer of natural peanut butter swirled through the batter creates pockets of toasty richness without pushing the fat content too high.

For anyone on GLP-1 medication, this is the kind of dessert that works with a smaller appetite rather than against it. A single wedge is dense and satisfying — you won't need a large portion to feel like you've had a real treat. The soft, custard-like texture is gentle on digestion, and the balanced macros mean your blood sugar stays steady rather than spiking and crashing the way it would with a traditional slice of cake.

Why This Works on GLP-1

Preserving lean muscle mass is one of the most important nutritional goals during GLP-1-assisted weight loss, and protein intake is the primary lever you have. At 28 grams per serving, this dessert delivers more protein than many people's entire lunch — and it does so in a format that feels indulgent rather than clinical. For those on Mounjaro or Wegovy who find their appetite significantly reduced, getting enough daily protein becomes a genuine challenge. Having a protein-dense dessert option means you can close the gap without forcing another savory meal.

The combination of whole eggs and egg whites provides complete protein with all essential amino acids, while cottage cheese adds casein — a slower-digesting protein that helps sustain satiety between meals. The oat flour contributes 2 grams of soluble fiber per serving, which supports steady digestion without the bloating that high-fiber supplements can cause.

Ripe bananas supply potassium and vitamin B6, both of which support energy metabolism and muscle function. The natural sugars in the banana caramelize gently during cooking, providing genuine sweetness without any added sugar — keeping total carbohydrates moderate at 42 grams per serving, with a meaningful portion coming from complex sources.

Ingredients (serves 2)

For the batter:

  • 3 large eggs
  • 2 large egg whites
  • ¾ cup (170g) low-fat cottage cheese (2%)
  • 2 medium ripe bananas
  • 1 tablespoon natural peanut butter (no sugar added)
  • ⅓ cup (30g) oat flour
  • 1 teaspoon pure vanilla extract
  • 1 teaspoon ground cinnamon
  • ¼ teaspoon baking powder
  • Pinch of fine sea salt
  • Nonstick cooking spray

For topping (optional):

  • 2 tablespoons plain nonfat Greek yogurt
  • A few thin banana slices
  • Light dusting of cinnamon

Instructions

Prepare the batter:

  1. Add the cottage cheese to a blender or small food processor and blend for 20–30 seconds until completely smooth with no visible curds. This step is essential — it gives the cake a silky texture and ensures the cottage cheese integrates fully rather than leaving grainy pockets.

  2. Peel the bananas and place them in a medium mixing bowl. Mash thoroughly with a fork until only small lumps remain. Riper bananas (with brown spots) work best because they're naturally sweeter and mash more easily, eliminating the need for added sugar.

  3. Add the blended cottage cheese, eggs, egg whites, peanut butter, and vanilla extract to the mashed banana. Whisk vigorously until the mixture is uniform and slightly frothy, about 45 seconds.

  4. Sprinkle the oat flour, cinnamon, baking powder, and salt over the wet ingredients. Fold gently with a spatula until just combined — overmixing will make the cake tough rather than custardy.

Cook the cake:

  1. Lightly coat an 8-inch (20cm) nonstick skillet with cooking spray and set it over low heat. Pour all the batter into the skillet and spread it evenly with a spatula. The low heat is critical — this cake cooks more like a thick custard than a pancake, and higher heat will burn the bottom before the center sets.

  2. Cover the skillet with a tight-fitting lid. Cook on low heat for 16–18 minutes without lifting the lid for the first 12 minutes. The steam trapped inside cooks the top surface while the bottom develops a golden crust. The cake is ready to flip when the edges look set and the center no longer appears liquid when you gently shake the pan.

  3. Place a large plate over the skillet, and in one confident motion, invert the cake onto the plate. Slide it back into the skillet, uncooked side down. Cook uncovered for 3–4 minutes more until the second side is lightly golden and the center feels firm when pressed gently.

  4. Slide the cake onto a cutting board and let it rest for 3 minutes — this allows the custard interior to set fully and makes cleaner slices.

Serve:

  1. Cut the cake into two equal wedges. Top each with a tablespoon of Greek yogurt, a few banana slices, and a dusting of cinnamon if desired. Serve warm.

Practical Notes

Banana ripeness matters more than you think. Use bananas with plenty of brown spots on the skin — they provide all the sweetness this recipe needs without any added sugar. If your bananas are still mostly yellow, the cake will taste bland. You can quickly ripen bananas by placing them in a 300°F (150°C) oven for 15 minutes until the skins turn black.

Make your own oat flour in seconds. Pulse rolled oats in a blender for 10–15 seconds until powdery. One-third cup of oat flour requires about ⅓ cup plus 1 tablespoon of whole rolled oats. This is cheaper than buying oat flour and means you likely already have everything for this recipe in your kitchen.

The flip technique takes confidence. If flipping the cake feels risky, skip it entirely. Instead, after the initial 18 minutes of covered cooking, place the skillet under your oven broiler set to low for 2–3 minutes to finish the top. Watch it closely — it goes from golden to burnt quickly.

Start with half a serving if you're in early GLP-1 treatment. When appetite suppression is strongest, a full wedge may be more than you can comfortably eat. Cut the cake into quarters instead and save the rest — the macro density means even a quarter serving still gives you 14 grams of protein.

Pair it with something light if this is your evening dessert. The balanced macros in this cake make it substantial enough to serve as a late afternoon snack on its own, or as a dessert after a lighter dinner like soup or a salad. Avoid pairing it with another heavy protein dish, as the combination may feel too filling for a suppressed appetite.

Frequently Asked Questions

Will this cake feel too heavy on my stomach during GLP-1 treatment?
The texture is more like a soft custard than a dense traditional cake, which makes it easier to digest than baked goods made with butter and refined flour. The eggs and cottage cheese are both highly digestible protein sources that break down without taxing your stomach. That said, if you're in the first few weeks of Zepbound or Ozempic treatment and experiencing significant nausea, eat slowly and start with a smaller portion. Let it cool slightly before eating — warm food is generally better tolerated than hot food during early adjustment periods.
Can I make this without peanut butter for an allergy-friendly version?
Yes. Replace the peanut butter with 1 tablespoon of sunflower seed butter or tahini for a nut-free version with similar protein content and richness. You can also omit the nut butter entirely and add an extra egg white to compensate for the lost protein — the cake will be slightly less rich but still hold together well. Almond butter works as a direct substitute if tree nuts are not an issue.
How should I store leftovers and how long do they keep?
Wrap the remaining wedge tightly in plastic wrap or place it in an airtight container and refrigerate for up to 3 days. Reheat gently in a skillet over low heat for 2–3 minutes per side, or microwave in 20-second intervals until warmed through. The texture becomes slightly denser when cold, which some people actually prefer — it eats a bit like a thick protein bar straight from the fridge. Do not freeze this cake, as the cottage cheese and egg custard texture becomes watery upon thawing.
What if I can only eat a very small portion — is it still worth making?
Absolutely. Cut the finished cake into four smaller wedges instead of two. Each quarter still provides approximately 14 grams of protein and around 198 calories — meaningful nutrition for a small dessert or snack. The recipe scales well to a single serving too: use 1 egg, 1 egg white, ⅓ cup cottage cheese, 1 banana, 1½ teaspoons peanut butter, and 2 tablespoons oat flour. Cook in a 6-inch skillet for about 12 minutes covered, then 2 minutes uncovered.
Why does the recipe call for both whole eggs and egg whites?
Whole eggs provide fat, flavor, and emulsification — the yolks help bind the batter and give the cake its rich, golden color and custardy mouthfeel. The additional egg whites boost the total protein significantly without adding extra fat or calories. Two egg whites contribute about 7 grams of pure protein at only 34 calories. If you only have whole eggs, you can use 4 whole eggs total and skip the whites — the cake will be slightly richer (about 35 extra calories and 5 extra grams of fat per serving) but will still taste excellent.
