Bourbon Biscoff Blondies
Medically reviewed by Christiana George Updated Date: December 18, 2022


Last week I was so busy putting together my daughter’s birthday party and getting the house ready for my in-laws who were coming into town, I didn’t have time to share these lovelies. Now of course, I have to stare at this drool worthy photo and remember how insanely delicious these Bourbon Biscoff Blondies were. Not only are they fabulous alone, but they are even better with a scoop of vanilla ice cream and my easy Bourbon Caramel Sauce. So if you want to make your father something special for Father’s Day this year, try these. He’ll love you for it.

I just can’t get enough of Biscoff and Bourbon. This time I even added in some pecans to the mix.

I did not hold back on the bourbon. I went for a full 1/4 cup. You could definitely smell the booze. The batter was still pretty thick, so I wasn’t too concerned about the blondies baking properly.

In fact, they baked beautifully. You could still smell the booze, but you could also smell the Biscoff and chocolate chips.

I did attempt to cut the bars while they were still slightly warm, but it was difficult to do without them breaking apart. So before continuing, I placed them in the fridge for about 20 minutes, then I finished cutting them. That way I had much cleaner cuts.

Now, you could eat them plain, just like this, or you can make them extra special. Grab a 1/4 cup of caramel topping and mix in a teaspoon of bourbon.

Then warm up you slice of blondie in the microwave for 20-30 seconds. Top it with a scoop of vanilla ice cream and pour a little or a lot of Bourbon Caramel Sauce over the top. It’s life changing, trust me.

This ooey, gooey mess is good to the last drop. You can taste all the flavors, the bourbon, the biscoff, and the chocolate chips. Add to that the caramel and the crunch of pecans. It’s flavor overload for the taste-buds. I was kind enough to share these with my neighbors. They rarely say no to my treats. I know my husband would like me to make some more for him on Father’s Day. I think he deserves them!

Ingredients (16 bars)
For the blondies
- 1 cup + 1 tablespoon all purpose flour
- 1/2 teaspoon baking powder
- 1/8 teaspoon baking soda
- 1/2 teaspoon salt
- 5 tablespoons unsalted butter, melted
- 1 cup light brown sugar
- 1 large egg + 1 egg yolk
- 1 teaspoon vanilla extract
- 1/4 cup bourbon whiskey
- 1/2 cup Biscoff spread
- 1 cup semi-sweet chocolate chips
- 1/2 cup chopped pecans
For the sauce
- 1/4 cup caramel sauce
- 1 teaspoon bourbon whiskey
Instructions
For the blondies
Preheat oven to 350°F.
Line the bottom and sides of an 8 x 8 inch baking pan with aluminum foil.
In a small bowl, mix together the cup of flour, baking powder, baking soda, and salt.
Place the melted butter and brown sugar in a stand mixer bowl and mix until combined.
Then add in the egg, egg yolk, vanilla, bourbon and Biscoff. Mix on low speed until smooth.
Slowly add the dry ingredients to the wet ingredients. The batter will be very thick. Do not over mix, or the blondies will turn out hard.
Lastly, mix the remaining tablespoon of flour with the chocolate chips and add them to the mixer bowl along with the pecans. Mix until evenly distributed.
Spoon the batter into the lined baking dish. Bake for 25-26 minutes or until a toothpick inserted in the center comes out almost clean. The blondies may appear soft, but they will set up as they cool.
Allow the blondies to cool completely, about 3 hours. You can place them in the fridge for 20-30 minutes to speed up the process.
Once cooled, gently lift the foil out of the pan, place the blondies on a cutting board and cut into squares.
For the sauce
In a small bowl, whisk together the caramel and the bourbon. When ready to serve drizzle some over a blondie square. Vanilla ice cream is optional.
Notes
Blondies can be made ahead of time and stored in an airtight container at room temperature for about a week.

Swirls And Chocolate Peanut Butter Tarts

The same laws of nature that cause the half and half to swish through my iced coffee preside over the universe, and hence the universe resides in a cup. The swishes and swirls, on a macro level, remind me of photos I’ve seen of nebulae, frozen moments of a frenetic, cosmic dance. They’re gossamer and ghostly and seem to encompass all that is mysterious, ephemeral, and otherworldly. I like the juxtaposition of the two ideas as I prepare my morning cup.

I’ve been enamored with culinary swirls lately, the ones that happen effortlessly through the process of mixing and folding and pouring. I’m not sure anything manmade can emulate the unintended complexity that such acts bloom into being, though I’m sure the masters at Pixar are certainly trying.
I especially love the streaks that occur when chocolate is folded into meringues.


And when peanut butter is folded into a chocolate tart.


Onto other topics. I’ve been nominated for a Saveur Best Food Blogs award in the Best Photography category! What an honor! And I’m really kind of flabbergasted. I mean, I’m sure that among the minimum requirements that must be met in order to be considered a food blog, consistency is one of them? Did I mention this news is weeks-old? But, cool beans anyway! Thank you to whoever nominated me!

Finally, because this IS a food blog, I’m going to leave you with the recipe for the chocolate peanut butter tarts shown above. I’ve made them four times in the last couple weeks—for two birthdays and twice just because—and think I’ve got the recipe down. While the original recipe is intended for a 9″ tart pan, individual tarts trump giant tarts, period. The crust to filling ratio is just about perfect, and they look damn cute too. The swirls are formed simply by dropping warmed-up peanut butter in teaspoonfuls onto the chocolate, then swirling them around with a skewer. There’s no way to mess up—nature will take care of all the intricacies.
CHOCOLATE PEANUT BUTTER TARTS
Adapted from Chow Makes 4 3.5″-tarts
Ingredients:
For the crust:
1/4 cup (half a stick) unsalted butter, melted
2 T granulated sugar
pinch salt
1/2 cup + 2 T all-purpose flour
For the filling:
6 oz. semi-sweet chocolate
2 T unsalted butter
1/2 cup heavy cream
2 T granulated sugar
pinch salt
2 to 3 T smooth peanut putter for swirling
Directions:
For the crust: In a small bowl, mix the butter, sugar, and salt. Add the flour and gently mix until just combined. Divide the dough into four equal pieces and press each piece evenly into 3.5″ tart pans, including up the sides. Trim the tops and place the tart pans in the fridge until firm, 15 – 30 minutes. Preheat oven to 350 degrees F.
When firm, remove the crusts from the fridge and prick evenly with a fork. Bake about 20 minutes until golden brown. Remove from oven and let cool.
For the filling: While the crusts are cooling, melt the chocolate and butter in a double-broiler. In a small saucepan, heat the heavy cream, sugar, and salt until boiling, then reduce heat to low and simmer for 1 minute. Pour the cream mixture over the chocolate and stir until evenly combined. Pour the chocolate mixture evenly into the tart pans and let cool for about 10 minutes.
Heat up the peanut butter (the microwave works best) so that it’s runny, about 20 seconds. Using a teaspoon, drop mounds of peanut butter onto the chocolate ganache. Use as much or as little as you want; you’ll have to experiment to discover your preferences. Using a skewer or a chopstick, gently swirl through peanut butter in swoops. Don’t overdo it or the pattern will dilute.
Let set for another hour or so until the tarts aren’t quite as jiggly. You can also refrigerate the tarts at this point, but they taste better at room temperature, so remove them from the fridge about an hour before serving.
