Ingredients for 1st phorm protein mug cake
Four servings of protein-packed indulgence with just 12 simple ingredients.
| Ingredient | Amount | Notes |
|---|---|---|
| 1st Phorm Protein Blend 🥛 | ¾ cup | Vanilla or chocolate flavor preferred |
| Large Egg Whites 🥚 | 4 whole | Room temperature for best texture |
| Unsweetened Almond Milk 🥛 | ¼ cup | Vanilla almond milk adds flavor |
| Granulated Sweetener 🍯 | 2 tbsp | Sucralose or monk fruit preferred |
| Unsalted Butter 🧈 | 1 tbsp | Melted, full-fat for richness |
| Dark Chocolate Chips 🍫 | ¼ cup | 70% cocoa or higher |
| Cocoa Powder 🍫 | 2 tbsp | Dutch-processed for smoothness |
| Baking Powder 🍞 | ½ tsp | Ensures proper rise |
| Vanilla Extract 🌸 | ½ tsp | Pure, high-quality extract |
| Pinch of Salt 🧂 | ⅛ tsp | Enhances chocolate flavor |
| Cinnamon 🍃 | ¼ tsp | Optional, for warm spice |
| Peanut Butter 🥜 | 1 tbsp | Creamy, natural style |
The 1st Phorm protein blend is the star here—grab the vanilla or chocolate version, whichever matches your craving. Costco or Amazon usually have it in stock, but check the protein label first; aim for at least 20g per serving. Egg whites are non-negotiable for that perfect texture—liquid egg whites from the refrigerated section work too. For the almond milk, Silk or Blue Diamond brands are my go-tos; unsweetened keeps the sugar in check. The sweetener matters: Lakanto or Swerve mimic sugar’s texture better than powdered versions. If you’re using butter, Land O’Lakes or Kerrygold melt beautifully without burning.
No vanilla extract? Almond extract at half the amount works in a pinch, though it tastes different. Running low on cocoa powder? Melted dark chocolate chipsnatural PB with no added sugar keeps it clean. For chocolate chips, Enjoy Life brand is allergy-friendly and melts perfectly. Want extra decadence? Add a dollop of Greek yogurt or whipped cream after baking. The cinnamon is purely for flavor, so skip it if you’re strictly tracking macros.
Prep ahead by measuring everything into small containers—4 mugs ready to go. The batter keeps 2 days in the fridge, covered with plastic wrap. For longer storage, freeze portions in silicone mug molds—microwave straight from frozen, adding 30 seconds. The protein blend absorbs moisture over time, so if your batter seems too thick, add 1 tsp more almond milk. This recipe doubles easily, but stick to 4 servings for perfect texture—more batter means longer microwave times and potential dryness.

Step-by-step instructions for 1st Phorm protein mug cake
Here’s how to create a perfectly fluffy, protein-packed mug cake in minutes.
👨🍳 Step 1: Melt Butter and Mix Wet Ingredients
Start by melting the 1 tablespoon unsalted butter in your microwave for 20-30 seconds or until completely liquid. Transfer it to a microwave-safe mug and let it cool slightly for 30 seconds—this prevents scrambling when you add the egg whites.
In a separate bowl, whisk together the 4 whole large egg whites, 0.25 cup unsweetened almond milk, 0.75 cup 1st Phorm Protein Blend, 2 tablespoons granulated sweetener, and the 0.5 teaspoon vanilla extract. I like to use a fork for this step—it creates small air pockets that help with the rise. Pour this mixture into the mug with the melted butter and stir until fully combined.
🍳 Step 2: Add Dry Ingredients and Fold Gently
In the same bowl you used for the wet ingredients, sift together the 2 tablespoons cocoa powder, 0.5 teaspoon baking powder, 0.125 teaspoon pinch of salt, and 0.25 teaspoon cinnamon. This ensures even distribution and prevents clumping. Gently fold these dry ingredients into your wet mixture using a silicone spatula, being careful not to overmix—just until no dry spots remain.
Here’s the thing—overmixing develops gluten in the egg whites, which can make your cake dense instead of light and airy. You want to see a few streaks of cocoa powder when you stop mixing. Fold in the 1 tablespoon peanut butter and 0.25 cup dark chocolate chips next, making sure the chocolate chips are evenly distributed throughout.
🔥 Step 3: Microwave to Perfect Doneness
Place the mug in the microwave and cook on high power (100%) for 60-75 seconds. Watch closely during the last 20 seconds—you’re aiming for a cake that’s just set but still slightly jiggly in the center. The top should look dry to the touch, and a toothpick inserted should come out with a few moist crumbs but no wet batter.
If your microwave varies in power, start with 60 seconds and check immediately. The cake will continue cooking slightly after you remove it from the microwave, so it’s better to err on the underdone side. I know it’s tempting to peek, but resist—every time you open the door, you release steam that can cause uneven cooking.
⏰ Step 4: Rest and Serve Warm
Let the mug cake rest for 1-2 minutes after microwaving. This brief resting period allows the cake to set properly and prevents it from falling apart when you try to cut it. The texture will transform from slightly wobbly to perfectly firm during this time.
Run a knife around the edges to loosen it from the mug, then invert onto a plate if desired. Serve warm for the best texture—each bite should deliver a perfect balance of rich chocolate flavor, creamy peanut butter swirls, and a tender yet slightly dense protein-packed crumb. You’ll love how this single-serving treat satisfies both your sweet tooth and your protein goals!
Pro Tips For Making 1st Phorm Protein Mug Cake
- Whip Egg Whites Cold: Grab the bowl of egg whites straight from the fridge—room temperature makes them clingy and hard to fold. I learned this the hard way when my first batch turned into a dense, sad pancake instead of a fluffy cake.
- Melt Butter First: Warm the unsalted butter until it’s just liquid, then let it cool slightly before mixing it in. Cold butter creates lumps that won’t blend smoothly, and you’ll end up with a cake that looks like it’s got hidden rocks.
- Skip Overmixing: Stir the batter just until the protein powder dissolves—about 10-12 strokes max. Overmixing turns your cake into a tough, rubbery brick. I used to go at it like I was kneading dough, and it was a disaster.
- Microwave in 30-Second Bursts: Heat the mug cake in 30-second intervals, checking after each one. The protein blend can dry out fast, and you want to avoid a gummy center or a burnt top. It’s not the fastest method, but it guarantees perfect doneness every time.
Wine and beer pairings for 1st phorm protein mug cake
Sweet Contrasts
Pair this mug cake with a light, fruity wine like Moscato d’Asti—its delicate bubbles and berry notes complement the chocolate without overpowering the protein profile. The slight sweetness mirrors the cake’s richness, while the effervescence cleanses your palate between bites. 🍷
For a non-alcoholic option, try sparkling apple cider (like Martinelli’s) chilled to 40°F. The crisp acidity balances the peanut butter’s creaminess, and the natural sweetness enhances the chocolate flavor. Serve it in a small glass alongside the cake for a refreshing contrast.
Creamy Complements
A vanilla bean ice cream (like Breyer’s) adds a luxurious touch when served alongside. The cold creaminess contrasts beautifully with the warm mug cake, creating a restaurant-style dessert experience. Opt for full-fat to enhance the richness without overwhelming the protein content.
For a lighter option, dollop Greek yogurt (like Fage 5%) on top. Its tangy sweetness cuts through the chocolate intensity, while the extra protein boosts your post-workout recovery. Choose vanilla-flavored to harmonize with the cake’s vanilla undertones.
Coffee Pairings
If you prefer coffee, a strong espresso (like Starbucks Pike Place) works surprisingly well. The bold, bitter notes enhance the chocolate’s depth, while the caffeine helps metabolize the protein more efficiently. Serve it black or with a splash of almond milk to avoid competing flavors.
For a smoother experience, try a cold brew concentrate (like Stumptown) mixed with oat milk. The nutty undertones pair perfectly with the peanut butter swirls, creating a cohesive flavor profile that feels intentional and indulgent.
Beer Options
A Belgian-style witbier (like Hoegaarden) adds a unique twist with its coriander and citrus notes. The effervescence and slight tartness balance the cake’s richness, while the alcohol content helps with protein absorption. Serve it well-chilled to highlight its crispness.
For a lighter beer, a wheat ale (like Blue Moon) offers a subtle sweetness that complements the chocolate without overpowering it. The smooth finish lets the mug cake’s flavors shine, making it a great choice for those who prefer beer with dessert.
Nutrition facts
Frequently asked questions
Can I use regular flour instead of 1st Phorm protein powder?
No, the protein powder is essential for that high-protein texture and flavor. The blend creates a dense yet moist crumb that regular flour can’t replicate. If you’re avoiding protein powder, try a gluten-free flour blend mixed with 1 scoop of vanilla whey protein for similar results.
Why is my mug cake gummy instead of fluffy?
Overmixing or undercooking usually causes gummy texture. Mix just until combined (small streaks of cocoa powder are fine), and microwave for 60-75 seconds—stop when the top looks dry. If it’s still gummy, try adding 1 extra egg white next time to improve structure.
Can I make this ahead and freeze it?
Prepare the batter and freeze it in a silicone mug mold for up to 1 month. Microwave from frozen for 90-105 seconds, adding 15 seconds if needed. For best texture, thaw overnight in the fridge and microwave fresh the next day.
What’s the best way to make it keto-friendly?
Swap the granulated sweetener for erythritol or monk fruit blend, and use unsweetened almond milk and butter as-is. For extra richness, add 1 tablespoon coconut oil to the melted butter. The protein powder keeps it keto-friendly while delivering that decadent taste.
Can I use this recipe with other protein powders?
Yes, but results may vary. Whey protein works best for texture, while plant-based powders like pea or soy may make the cake denser. For optimal results, stick with 1st Phorm or vanilla whey isolate—these blends dissolve smoothly and don’t alter the chocolate flavor.
