    How to make Keto Peanut Butter Cups: step-by-step guide

    Cooking methods

    • No-cook recipe

    Preparation steps

    1. Gather all your ingredients and measure them according to the recipe.
    2. Melt the coconut oil in a microwave-safe bowl.
    3. Arrange the mini cupcake liners on a tray and make sure they're spread out evenly.

    Instruction steps

    1. Combine the melted coconut oil, peanut butter, vanilla extract, and erythritol in a mixing bowl.
    2. Stir the mixture until everything blends smoothly, forming the peanut butter filling base.
    3. Split the prepared peanut butter mixture in two. Add unsweetened cocoa powder to one half and mix well, creating a chocolatey base.
    4. Set mini cupcake liners on the tray. Fill each cup about a quarter full with the cocoa peanut butter mix, then gently smooth the surface with a spoon.
    5. Place the tray in the freezer for 40-50 minutes for the base to firm up.
    6. Once the first layer is solid, take the tray from the freezer.
    7. Fill the cups halfway with the non-cocoa peanut butter mixture.
    8. Put the tray back in the freezer, allowing the peanut butter cups to freeze for 50-60 minutes until firm.
    9. When they're completely frozen, remove the cups from the molds and serve!

    Chef's pro tip

    When you mix the melted coconut oil, ensure it's not too hot. Why? If it's too hot, it might affect the texture and create lumps. So, after melting the coconut oil, let it cool down a bit before you proceed. This easy step guarantees that you'll achieve that creamy perfection every time!

    What to serve with the peanut butter cups?

    Wondering what goes well with these peanut butter keto cups? Here are some tasty ideas:

    • Keto ice cream: Adding a scoop of Peanut Butter Ice Cream or Cottage Cheese Ice Cream on top creates a fancy dessert combo.
    • Fresh berries: The lively tang of fresh berries blends nicely with the rich and creamy peanut butter.

    How to make it healthier?

    • Opt for organic or homemade peanut butter to improve the nutritional profile.
    • Choose unsalted peanut butter to reduce the sodium content.
    • Swap out erythritol for natural sweeteners like stevia or monk fruit.

    Time-saving tips

    • Use a mixer: Try an electric hand mixer for quicker ingredient mixing.
    • Make more: Make a double batch if you're in the peanut butter cup mood. You'll have extra treats for later with just a bit more prep time.
