Ingredient Overview:

  • Cookie Butter – Lotus Biscoff spread (also called cookie butter), is made by Biscoff, but you can of course use any brand of cookie spreads that you like (Trader Joe’s makes a great one!).
  • Biscoff Cookie Crumbs Lotus Biscoff Biscuits (cookies) are a classic. You can find these near the cookies in most grocery stores. They’re sometimes called speculoos cookies.
  • Butter – I always use salted buter for the best flavor, but feel free to use unsalted butter if you prefer.
  • Cinnamon – A hint of cinnamon pairs so well with the warm flavor of the cookie butter.
  • Flour – All-purpose flour is the way to go here! No need for cake flour or anything else.
  • Vanilla extract – Be sure to use real vanilla extract for the best results.

Ingredient Substitutions:

  • Dairy-free – Use your favorite dairy-free butter and sour cream to make this biscoff mug cake recipe dairy-free.
  • Sour Cream – Greek yogurt can be subbed for sour cream.

How to Make this Biscoff Mug Cake Recipe Step-by-Step:

Step 1: Combine wet ingredients. Whisk together the melted butter, cookie butter, sugars, egg, and vanilla.

Step 2: Combine dry ingredients. Add the dry ingredients and gently fold them in until just combined.

Step 3: Microwave the cake. Pour the batter into a large microwave-safe mug sprayed with nonstick spray. Microwave as directed in the cooking time in the recipe card below for best results.

Top your mug cake with a drizzle of melted cookie butter, a sprinkle of biscoff cookie crumbs, and top with a scoop of vanilla ice cream or whipped cream. This is a great way to satisfy your sweet tooth emergency cake cravings!

Expert Success Tips:

  • Don’t Over Mix – Over mixing your batter can lead to a tough or less fluffy cake.
  • Kitchen Scale – A food scale is the best way to make sure your flour is at the proper weight, since amounts will vary SO widely based on how you measure it, as well as the measuring cup you use, as they are not standardized.

FAQs:

Can I halve this recipe?

Yes! Cut the recipe in half to make just one single serving.

Can I make this ahead?

No, I don’t recommend making microwave mug cakes ahead. It’s the easiest dessert though!

Can I bake this mug cake in the oven?

I don’t recommend baking these in the oven because of the depth of the mugs. The outer part of the cake will be overdone by the time the center cooks through. Try my easy one-layer Biscoff Cake instead!

Recipe Variations:

  • Extra Cookie Butter Drizzle – Poke holes in the top of your baked cake with the back of a wooden spoon and drizzle in melted cookie butter.
  • Other Nut Butters – Try peanut butter or almond butter instead of the cookie butter in this recipe (disclaimer – I have not tried this, but the general consensus is that it works). Avoid natural nut butters.

Ingredients 

For the Mug Cakes

  • 4 tbsp salted butter, melted
  • 3 tbsp cookie butter
  • 1/2 cup + 2 tbsp brown sugar
  • 2 large eggs, at room temperature
  • 3/4 tsp vanilla extract
  • 2/3 cup cake flour, spooned & leveled, 78 grams
  • 1/4 cup biscoff cookie crumbs (3-4 cookies)
  • pinch of salt
  • 1/8 tsp baking powder
  • 1/8 tsp baking soda
  • 2 tbsp vegetable oil
  • 1/4 cup sour cream, or greek yogurt, full fat

For Topping

  • crushed biscoff cookies
  • melted cookie butter
  • vanilla ice cream

Instructions 

  • Make the Mug Cake Batter: Melt the butter in a medium mixing bowl. Whisk in the cookie butter, then the sugar. Whisk in the eggs, and vanilla. Stir in the dry ingredients.
  • Microwave the Mug Cakes: Spray two mugs with nonstick spray, and divide the batter between the two. Microwave one at a time, for about 1 minute 30 to 1 minute 50 seconds. A toothpick inserted into the center will come out clean or have moist crumbs, not wet batter.
  • Cookie Butter Drizzle: Poke holes in the cake with the back of a wooden spoon or something similar, and drizzle in melted cookie butter.
  • Serve + store: Serve the mug cakes while they're warm, with a drizzle of melted cookie butter, a sprinkle of biscoff cookie crumbs, and a scoop of vanilla ice cream.

    Can this be baked instead of microwaved?

    1. Stephanie Simmons says:

      I think this is mentioned in the post, but no I donโ€™t recommend it as it takes quite a long time to bake because of the depth of a mug vs. a cake pan. I compared the two and preferred the microwaved one! The outside of the baked one was a bit dry due to the long bake time to get the center cooked. Let me know if you try this! โ˜บ๏ธ
