How to Make Keto Peanut Butter Pecan Mug Cake

PIN IT

1. Mix Wet Ingredients: In your mug, combine the peanut butter, egg, heavy cream, and vanilla. Stir until smooth.
2. Add Dry Ingredients: Add almond flour, erythritol, baking powder, and a pinch of salt. Stir to fully combine.
3. Fold in Pecans: Gently stir in the chopped pecans.
4. Microwave: Heat on high for 60–75 seconds. The cake should rise and firm up but still be slightly soft in the center.
5. Serve: Enjoy straight from the mug, or top with a dollop of whipped cream or a drizzle of more peanut butter.

It smells divine while cooking—like warm peanut butter cookies just out of the oven!

What to Serve with Keto Peanut Butter Pecan Mug Cake

• A scoop of keto vanilla ice cream
• Fresh berries for a fruity contrast
• Coffee with heavy cream or a chai latte
• A drizzle of sugar-free caramel syrup

Tips for Making It Perfect

• Microwave times vary: Start at 60 seconds and add 10-second increments if needed.
• Don’t overmix: Mix just until ingredients are combined for a fluffy texture.
• Use a wide mug: This helps the cake rise evenly and prevents overflow.
• Add toppings after cooking: Don’t microwave with whipped cream or chocolate chips unless you want melted pockets.

Storage Instructions

This mug cake is best enjoyed fresh, but you can:

• Make ahead: Mix ingredients and refrigerate, then microwave when ready.
• Store leftovers: Cover and refrigerate for up to 24 hours. Reheat gently in the microwave for 15–20 seconds.
• Freeze? Not ideal due to egg texture, but doable. Wrap tightly and freeze up to 2 weeks.

Frequently Asked Questions

Can I use coconut flour instead of almond flour?
Coconut flour absorbs more liquid, so you’d need only 1 tsp and possibly more cream. I recommend sticking to almond flour unless you adjust the ratios.

What kind of peanut butter works best?
Smooth, unsweetened peanut butter works best—avoid brands with added sugar or oils.

Is it really keto?
Yes! With sugar-free ingredients and low-carb flour, it’s perfectly keto.

How many carbs are in this recipe?
Roughly 3g net carbs, depending on your sweetener and peanut butter brand.

Can I make this dairy-free?
Absolutely—just swap the heavy cream for coconut cream or almond milk.
